Bacteria identification and food quality monitoring using biosensors; intelligent, active, and smart food packaging systems; nanoencapsulation of bioactive food compounds are few examples of emerging applications of nanotechnology for the food industry.[2] Nanotechnology can be applied in the production, processing, safety and packaging of food.
Nanoparticles are promising candidates for implementation in agriculture. Because many organic functions such as ion exchange and plant gene expression operate on small scales, nanomaterials offer a toolset that works at just the right scale to provide efficient, targeted delivery to living cells.

For some applications, nanoparticles may be characterized in complex matrices such as water, soil, food, polymers, inks, complex mixtures of organic liquids such as in cosmetics, or blood. [132] [133] There are several overall categories of methods used to characterize nanoparticles.
A new way of smuggling ragweed, peanut proteins or other allergens past the immune system could finally teach our bodies not to overreact.
The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,. [1] Nanoparticles measure less than 100 nanometers in at least one of their external dimensions, and are often engineered for their unique properties.
The opportunity for functionalizing nanoparticles in such ways is especially beneficial when targeting areas of the body that have certain physiochemical properties that prevent the intended drug from reaching the targeted area alone; for example, some nanoparticles are able to bypass the Blood Brain Barrier to deliver therapeutic drugs to the ...
An example of this has occurred in the US, and involves nanoparticles of titanium dioxide (TiO 2) for use in sunscreen where they create a clearer cosmetic appearance. In this case, the US Food and Drug Administration (FDA) reviewed the immediate health effects of exposure to nanoparticles of TiO 2 for consumers.
This method makes nanocapsules more stable, and increases shelf-life of foods. [1] Freeze-drying – This process involves dehydration of materials that are heat-sensitive. Unlike spray drying, water is removed through the sublimation process without changing the structure or shape of the nanoparticles. Freeze-drying involves four states ...
