Abstract

The polyol method, microemulsions, thermal decomposition, electrochemical synthesis, chemical vapor deposition, microwave irradiation, pulsed laser method, sonochemical reduction, and gamma radiation are just a few of the many techniques used in the synthesis and characterization of silver nanoparticles (Ag NPs). These methods apply to several kinds of nanoparticles, including metal, ceramic, lipid-based, carbon-based, and polymeric nanoparticles. Their characterisation heavily relies on analytical techniques including Energy Dispersive Analysis of X- Rays (EDAX), UV Spectroscopy, and Scanning Electron Microscopy (SEM). The rapidly developing area of nanotechnology provides insight into the enormous benefits of nanoparticles that go beyond traditional thinking. Their integration cuts across several industries, including consumer products, food, healthcare, and medicine. The development and Synthesis of nanopesticides and nanofertilizers from cowdung and neem tree parts was done by utilizing principles from nanotechnology. Synthesized nanoparticles were characterized using SEM & EDAX & Synthesis of nano particles was monitored using UV-Spectrophotometer. Also, Evaluation of the impact of synthesized nanoparticles on the germination process of tomato seeds was carried out & positive results were obtained. Hence using this as a model it was concluded that nanoparticles do have their potential applications in agriculture and beyond.
