ABSTRACT
The predominance approach of the metal nanoparticles (NPs) in the biological application, made its importance towards the production techniques as well as in the food or biological material. Major emphasis is being focused upon various parameters to enhance the production of the NPs on a wider scale. The vastly applied synthesis/production approach to the NPs is the use of chemicals having a reduction and capping ability. As the synthesis comprises of chemicals use which have impacted our mother nature adversely, therefore it is quintessential to effectively reduce the usage of chemicals in such processes. Previously many experimental approaches have been applied to reduce the usage of chemicals in NPs synthesis like ball milling, electron beam lithography, pulsed laser ablation/deposition, etc. A relatively innovative idea is the utilization of plant material for NPs synthesis along with the production of NPs on a large scale which may possess important properties and applications in food packaging as well. Antimicrobial proficient NPs like silver, gold, copper, etc., are potent antimicrobial agents, which create a barrier to small organic molecules and foodborne pathogens. NPs are included in bioavailable improved medicines, food technology as well as in cosmetics. Decreased size of NPs results in increased bioavailability or228increased potency of a drug with the decreased dosage amount. Further, drugloaded NPs have been seen to have lesser toxicity, and enhanced delivery as well, making them suitable agents, delivering the functional nutrients in food to humans.
