Applications of Nanoparticles in Agriculture Improvement- A Review

The field of nanotechnology is quickly developing and emerging since it has enormous potential for various human uses. With their unique, size-based physical and chemical attributes, nonmaterials generated and engineered through nanotechnology have many applications in biomedicine and agriculture. Theranostics is a branch of nanomedicine that uses small, highly surface-area nanoparticles to diagnose and treat diseases. Nanomaterials have a wide range of uses in agriculture, from fertilizers that improve soil nutrient uptake by plants to nano pesticides that control a variety of pests, including fungi, phytophagous insects, and weeds, increasing food output. Agriculture and food security are intimately connected, and many researchers are interested. Agriculture production depends on many difficulties due to the severe effects of climate change, water problems and changing the distribution of insect pests. Meanwhile, it faces tremendous challenges in maintaining food security for a massive population amid declining resources. Research is actively exploring the use of nonmaterial in agriculture due to their tremendous promise. Despite their good qualities, nonmaterial present risks to the environment and human health, necessitating risk assessment studies. Green nonmaterial synthesis may lessen the usage of toxic agrochemicals that pollute the environment and enter biological systems, providing an environmentally safe, environmentally friendly, and economically advantageous option. In this critical evaluation, nanoparticles are used in agriculture.

An Overview: Matrix Tablet as Controlled Drug Delivery System.

In past decade great interest got generated on replacing conventional administration of drug by delivery system which would release effective quantities from a protected supply at a controlled rate over a long period of time. An appropriately designated controlled release drug delivery system can be are major advance toward solving problems concerning targeting of a drug to a specific organ or a tissue and controlling the rate of a drug delivery to the target site. Matrix system are favoured because of their simplicity, patient compliance etc, than traditional drug delivery(TDS) which have many drawbacks like repeated administration, fluctuation in blood concentration level etc. Developing oral sustained release matrix tablet with constant release rate has always been a challenge to the pharmaceutical technologist. Most of drugs, if not formulated properly, may readily release the drug at a faster rate, and are likely to produce toxic concentration of the drug on oral administration. Hydrophilic polymers have become product of choice as an important ingredient for formulating sustained release formulations.
