“…There is tremendous interest in the synthesis of nanoscale size particles and composites that possess specific physical and chemical properties. These nanomaterials with unique properties pave a new path for their application in diverse areas like nanomedicine, food sector, pollution abatement and high energy storage devices [18,26–28] . The nanoparticle characteristics like particle size, surface charge, hydrodynamic diameter, can affect their biodistribution, intracellular movement, rate of uptake, agglomeration behaviour, photocatalytic efficiency, drug delivery, cytotoxicity, anti‐cancerous and antimicrobial activity [29–35] .…”
