How helpful is nanotechnology in agriculture?


The application of nanotechnology in agriculture aims, in particular, to reduce applications of plant protection products, minimize nutrient losses in fertilization, and increase yields through optimized nutrient management.

Nanotechnology devices and tools, like Nano capsules, nanoparticles, and even viral capsids, are examples of uses for the detection and treatment of diseases, the enhancement of nutrients absorption by plants, the delivery of active ingredients to specific sites and water treatment processes.

The use of target-specific nanoparticles can reduce the damage to non-target plant tissues and the number of chemicals released into the environment. Nanotechnology derived devices are also explored in the field of plant breeding and genetic transformation.

AREAS OF NANOSCIENCE RESEARCH AND APPLICATION IN AGRICULTURE AND FOOD SCIENCE

The contribution of nanoscience research in agriculture is and probably will be in the following areas:
• Food safety and biosecurity
• Material science
• Food processing and product development

Some of the examples of Nanoscience/Nanotechnology used in Agri and Allied segment is mentioned undesigned:

Nanosilver: Nanosilver is the most studied and utilized nanoparticle for bio-system. It has long been known to have strong inhibitory and bactericidal effects as well as a broad spectrum of antimicrobial activities. Silver nanoparticles, which have high surface area and a high fraction of surface atoms, have high antimicrobial effect as compared to the bulk silver.

Nano alumino-silicate: Leading chemical companies are now formulating efficient pesticides at the nanoscale. One of such effort is the use of alumino-silicate nanotubes with active ingredients. The advantage is that alumino-silicate nanotubes sprayed on plant surfaces are easily picked up in insect hairs. Insects actively groom and consume pesticide-filled nanotubes. They are biologically more active and relatively more environmentally-safe pesticides.

Titanium dioxide (TiO2) nanoparticles: Titanium dioxide (TiO2) is a non-toxic white pigment widely used in the manufacture of paints, study, ink, cosmetics, ceramics, leather, etc. and is a very strong disinfectant as compared to chlorine and ozone. Since TiO2 is harmless, it is approved for use in food products up to 1% of product final weight. TiO2 photocatalyst technique has great potential in various agricultural applications, including plant protection since it does not form toxic and dangerous compounds and possesses great pathogen disinfection efficiency.

What are the differences between smart materials, composite materials and nano materials?

Image
Smart materials are at least dual function, composites are materials composed of dissimilar phases or components (sometimes they’re called hybrid materials now), and Nano materials have been engineered on the Nano-scale Smart materials have multiple functions, which generally include sensor/actuator ability in addition to having form, or being able to support at least some structural weight. The classic example is Nitinol, which is a Nikcle-Titanium allow. After mechanical deformation (for example, bending), it can be heated up and will return to the pre-deformed structural shape. Lead-Zirconate-Titanate (PZT) is a ceramic, which responds to mechanical deformation by generating an electrical potential. In the reverse, an applied electrical potential leads to a geometric expansion of the material (actuator function). Composites are materials that are combinations of at least two different materials, which allow the engineering of desired properties (like tailoring mechanic...

What are some examples of smart materials?

Image
Smart material are those that change in response to changing conditions in their surrounding or in the application of other directed influences such as passing an electric charge through them. Modern products increasingly use them, shirts that change colour with changes in temperature. Smart materials are the materials that have one or more properties that can be significantly changed in a controlled style such as stress, temperature, moisture, pH, electric or magnetic fields. There are many types of smart material some of which are already common. Some examples are as following: Types of smart material Some types of smart materials include: Piezoelectric   - On applying a mechanical stress to these materials it generates an electric current. Piezoelectric microphones transform changes in pressure caused by sound waves into an electrical signal. Shape memory   - After deformation of these materials they remember their original shape and return back to i...
