Green Synthesis and Zeta Potential Measurement of Silver Nanoparticles

Nanotechnology

Nanotechnology has enormous potential in the fields of healthcare, right from effective drug delivering, diagnosing diseases more rapidly and sensitively, and delivering vaccines via aerosols and patches. The use of silver (Ag) nanoparticles is quite interesting both in the fields of medicine as well as in healthcare due to its various pharmacological properties. Zeta potential [ZP] can affect the pharmacokinetic properties of nano systems in the body and plays an important role in controlling the electrostatic interactions in particle dispersion. The zeta potential characterization is used to understand the nanometre size particles in the liquid. The current study focuses on the green synthesis of metallic nanoparticles from Ocimum tenuilforum (Tulsi) and Catharanthus roseus (Periwinkle) and comparing the zeta potential values of these nanoparticles. The zeta potential value of silver nanoparticles from Periwinkle extract showed good stability as compared to silver nanoparticles from Tulsi extract. The surface charge density of nanoparticles could be optimized further for minimal toxicity and effective intracellular delivery of encapsulated drugs.
