Pathogen detection with nanotechnology
Pathogen detection and detecting infected individuals during a pandemic is the foundation of any public health response. Without knowing who is infected with what, doctors, nurses, epidemiologists, and public services cannot coordinate, track, and treat the spread of disease.
In an article published in Advanced Healthcare Materials the team report a new method and device which is easy to use, works in the field, and can be built with commercially available materials. The pandemic may have given this research a nudge but without their collaborative approach based on ingenuity and problem solving, they wouldn’t have been poised to act once the pandemic hit.
In commercially available LAMP kits users test the pH of the sample after the reaction is complete to determine if the sample was positive. This is because the biochemical reaction that replicates DNA releases protons, which affects the pH. The more replication that occurs the more protons are released and the lower the pH of the sample.
To get that number she and her colleagues leveraged the LAMP reaction pH change and added a small electrode onto which a nanosized cluster of palladium is attached. Palladium is a catalyst for a reduction reaction with oxygen that takes electrons and produces water creating an easily measurable electrical potential using a USB-sized voltmeter. The key for this method is that pH affects the behavior of this reaction, so adding a drop from the LAMP reaction creates a detectable change in electrical potential from the baseline on the electrode.

The Future of Sustainable Agriculture with Nanotechnology
Agricultural applications of nanotechnology have the opportunity to revolutionize agricultural production. It contributes to the resolution of persistent agricultural challenges through advanced technology and materials. There is also fascinating information on commercially produced nano-enabled products used in agriculture and related industries.
Agriculture has always been the most essential and steady sector because it generates and supplies raw materials to the food and feed industries. The scarcity of environmental assets and the world's growing population requires agricultural production to be economically sustainable, viable, environmentally friendly, and efficient.
This change will be critical for achieving many goals in the coming year. Several strategies for replacing traditional agricultural practices have been developed by researchers over the last several centuries.
Nanotechnology is one evolving methodology that is believed to enhance sustainability efforts of modern agriculture, such as crop productivity through improved plant nutrition, water productivity, crop protection against insects and pathogens through the development of nano-enabled formulations, and environmental protection of degraded sites through nano-bioremediation.
The distinct physicochemical characteristics of nanoparticles (NPs) contribute significantly to their suitability for a wide range of applications.
Major Issue in Agricultures
The majority of these issues are usually related to pesticides, herbicides, fertilizers, and the proper use of these products. The distribution of nanoparticles in plants follows a distinct path with numerous advantages. Because of their essential properties, such as surface-to-volume ratio, size, and optical properties, nanoparticles have a high capacity to protect crops.
Nano-encapsulated pesticides and fertilizers dispensed via a technique that distributes the material in a controlled manner are a good example of NPs application. This method, too, is site-specific. This high-efficiency strategy is advantageous for protecting non-target microbes and other collateral repairs.
Nano Herbicides and Nano Fertilizer Usage
Challenges in Applying Nanotechnology
The main concerns of nano-enabled products are the possible future concentrations of nanoparticle used, since it has shown harmful effects at different levels at elevated doses. The continuous use of nano-enabled products, particularly in agriculture, has the potential to raise their content in soil and crops. The majority of the nano-enabled products shown in the tables/figures do not reveal the applied nanoparticles' concentration, particle size, name, or fabrication techniques.
Nanoparticles could be transmitted from root to leaf and leaf to root, eventually making their way into the food chain. Furthermore, they show large-scale bioretention and accumulation within living creatures, potentially exceeding safe levels. Even a small amount of NPs could be harmful to humans.
Toxicity at greater concentrations can cause developmental delays and inhibition. The toxicity of NPs, on the other hand, varies depending on their shape, size, concentration levels, base materials, and surface coating
Green Nanotechnology and Future Results
Green nanotechnology is an emerging field that is developing clean, safe, and ecologically friendly alternatives to product lines that are currently used in a variety of industries. As the name implies, they are generated from various plant parts, microbes, amino acids, glucose, and so on.
Based on recent studies, the current review investigated the use of nano-enabled commodities and discovered some intriguing features. Although, more scientific evidence about these or new nano-enabled goods is needed. Future research should focus on understanding the main mechanisms of nano-enabled products' interactions with the food supply chain, as well as their genomic consequences.

Antimicrobial Cotton Fabric Made from Silver Nanoparticle Nanogel
Bacteria on the Rise
Pathogenic bacteria are the greatest cause of mortality worldwide, with many diseases humans caused by microbe-infested surfaces. For a long time, antibiotics have dominated treatment techniques for bacterial infections and continue to do so. Despite significant improvements, antibiotic overuse has led to a dramatic surge of drug-resistant bacteria in recent decades, resulting in widespread disease and death.
To address this problem, one method is to improve antibiotic bioavailability while concurrently reducing the prescribed dose. Developing antimicrobial agents to treat bacterial illnesses effectively and reliably is therefore crucial.
How can Nanotechnology Help?
Recent advancements in nanotechnology present an alternate tactic in the fight against bacterial diseases owing to the specific chemical and physical characteristics of different nanoparticles.
Although silver ions are generally considered to be harmless for human cells and tissues, when analyzed on the nanoscale, there is growing concern regarding the toxicity of silver nanoparticles. The buildup of these nanoparticles in human organs and tissues may have harmful outcomes such as cell death or DNA damage. Moreover, silver NPs can be susceptible to oxidation which renders their long-term antibacterial impact insufficient.
These issues can be solved via the encapsulation of silver nanoparticles in a carrier, which is an effective strategy for achieving stability and long-lasting antimicrobial potency.
As a mild natural substance, chitosan (CS) demonstrates exceptional biocompatibility and biodegradability. However, its low solubility in water and mediocre antibacterial characteristics hampers its antibacterial uses, particularly in complicated antimicrobial systems. On the other hand, Quaternized chitosan (QCS), having constant positive ionic charges on the backbone, is soluble in water at elevated pH values and shows good antimicrobial capacity.
Many attempts have been made to create QCS/Ag NPs nanocomposites because of the antibacterial superiority offered by the synergized action of QCS and Ag NPs.
Inverse Miniemulsions for Preparing QCS/Ag CNGs
The study found that the inverse miniemulsion technique effectively creates QCS/Ag composite nanogels. The silver nanoparticles may be pre-loaded in the polar dispersion phase containing reactive materials.
In the continuous organic phase, nanoscale droplets are formed and stabilized by emulsification. Using the droplet nucleation method, each droplet may be seen as a nano-reactor, providing excellent encapsulation efficiency and adjustable loading of silver nanoparticles. Hence the inverse miniemulsion method trumps other heterogeneous approaches like inverse emulsion and microemulsion.
The developed QCS/Ag CNGs fused the special characteristics of QCS and silver nanoparticles, exhibiting effective antibacterial properties and minimal cytotoxicity. It is possible to chemically immobilize these composite nanogels on plasma-treated cotton textiles using a pad-dry-cure procedure that helps in retaining the antibacterial effects even after washing.
Properties of the Nanogel-Integrated Fabric
The silver composite nanogels developed in the study demonstrated impressive broad-spectrum antibacterial capability. Controlling the degree of cross-linkage and the QCS/Ag CNGs' dose allows the antibacterial effectiveness to be tuned as per requirements.
The growth of C. albicans, E. coli, and S. aureus was significantly suppressed under the optimum degree of cross-linkage. The high antibacterial efficacy shown by the silver composite nanogels, particularly against C. albicans (fungi), makes them suited for a wide range of antimicrobial purposes.
Incorporating antimicrobial properties in pure cotton textiles does not remove their essential qualities of water vapor absorption and permeability, elasticity, and tensile strength.
Researchers also found that the thermal stability of the pure cotton fabrics was not compromised with the addition of the silver nanogel composites, and the final product displayed similar levels of whiteness to those of the pure textiles. The addition of silver composite nanogels added a layer of protection in cotton fabrics against microbial pathogens without compromising any comfort-related characteristics of the textile.

Better imaging and diagnostic tools enabled by nanotechnology are paving the way for earlier diagnosis, more individualized treatment options, and better therapeutic success rates. Medicinal applications of nanotechnology are not only restricted to the aforementioned areas but are also seen in gene therapy, wound treatment, etc. where a nanoparticle can help to deliver medication directly to cancer cells instead of the whole body and minimize the risk of damage to healthy tissue. This has the potential to change the way doctors treat cancer and dramatically reduce the toxic effects of chemotherapy. Nanomedicine researchers are looking to improve vaccines and deliver vaccines without needles. and also searching to regenerative medicine spans, in the areas of bone and neural tissue engineering. Researchers are looking for ways to grow complex tissues with the goal of one-day growing human organs for transplant. and also looking to use graphene nanoribbons to help repair spinal cord injuries.
Energy
The power of nanotechnology has greatly enhanced alternative energy approaches to meet the growing demands of the world for energy. Scientists are looking into ideas and means to develop clean, affordable, and renewable energy sources, along with means to reduce energy consumption and lessen toxicity burdens on the environment. Nanotechnology is improving the efficiency of fuel production from raw petroleum materials through better catalysis. It is also enabling reduced fuel consumption in vehicles and power plants through higher-efficiency combustion and decreased friction. Nanotechnology can be incorporated into solar panels to convert sunlight to electricity more efficiently, promising inexpensive solar power in the future. Nanostructured solar cells could be cheaper to manufacture and easier to install. Nanotechnology is already being used to develop many new kinds of batteries for better charging, more efficiency, lighter weight, and higher power density.

Nanoparticles are being developed to clean industrial water pollutants which get accumulated in groundwater through chemical reactions. This is one of the best applications of Nanotechnology where unique nanoparticles are used to improve the quality of groundwater and rivers. Researchers have also placed magnetic water-repellent nanoparticles in oil spills and used magnets to mechanically remove the oil from the water. A nano fabric towel has been developed by researchers that can absorb 20 times its weight in oil for clean-up applications. Deteriorating air quality has become a global issue, Nanotechnology-enabled sensors and solutions are now able to detect and identify chemical or biological agents in the air and soil with much higher sensitivity. Graphene Oxide is being used to separate pollutants from the air, industrial plants, cars, air conditioners, etc.

Seeding the oceans with iron-rich fertilizer nanoparticles to store excess carbon dioxide
Seeding the oceans with iron-rich fertilizer nanoparticles to store excess carbon dioxide(Nanowerk News) The urgent need to remove excess carbon dioxide from Earth’s environment could include enlisting some of our planet’s smallest inhabitants, according to an international research team led by Michael Hochella of the Department of Energy’s Pacific Northwest National Laboratory. | |
Hochella and his colleagues examined the scientific evidence for seeding the oceans with iron-rich engineered fertilizer particles near ocean plankton. The goal would be to feed phytoplankton, microscopic plants that are a key part of the ocean ecosystem, to encourage growth and carbon dioxide (CO2) uptake. The analysis article appears in the journal Nature Nanotechnology("Potential use of engineered nanoparticles in ocean fertilization for large-scale atmospheric carbon dioxide removal"). |
“The idea is to augment existing processes,” said Hochella, a Laboratory fellow at Pacific Northwest National Laboratory. “Humans have fertilized the land to grow crops for centuries. We can learn to fertilize the oceans responsibly.” In nature, nutrients from the land reach oceans through rivers and blowing dust to fertilize plankton. The research team proposes moving this natural process one step further to help remove excess CO2 through the ocean. They studied evidence that suggests adding specific combinations of carefully engineered materials could effectively fertilize the oceans, encouraging phytoplankton to act as a carbon sink. The organisms would take up carbon in large quantities. Then, as they die, they would sink deep into the ocean, taking the excess carbon with them. Scientists say this proposed fertilization would simply speed up a natural process that already safely sequesters carbon in a form that could remove it from the atmosphere for thousands of years. “At this point, time is of the essence,” said Hochella. “To combat rising temperatures, we must decrease CO2 levels on a global scale. Examining all our options, including using the oceans as a CO2 sink, gives us the best chance of cooling the planet.” The researchers’ analysis of 123 published studies showed that numerous non-toxic metal-oxygen materials could safely enhance plankton growth. The stability, Earth abundance, and ease of creation of these materials make them viable options as plankton fertilizers, they argue. The team also analyzed the cost of creating and distributing different particles. While the process would be substantially more expensive than adding non-engineered materials, it would also be significantly more effective.
