‘Green Nanomaterial’-How Green they are as Biotherapeutic Tool

Debjani Nath, Pratyusha Banerjee and Bratati Das

The emergence of nanoparticles (NPs) has attracted tremendous interest of the scientific community for decades due to their unique properties and potential applications in diverse areas, including drug delivery and therapy. These opportunities are based on the unique properties (e.g., magnetic, optical, mechanical, and electronic) that vary continuously or abruptly with changes in the size of the materials at the nanoscale. Advances in nanotechnology have significantly impacted the field of therapeutics delivery. Although the impressive progress made in the design of disease-targeted NPs allows new treatments with improved specificity, only a few NP-based medicines have reached the market. There is a need for a new discipline-nanotoxicology-that would evaluate the health threats posed by nanoparticles, and would enable safe development of the emerging nanotechnology industry related to biotherapy. Green Nanotechnology gives the opportunity in lowering the risk of using nanomaterials, limiting the risk of producing nanomaterials, and using nanomaterials to lower the risk of producing unwanted chemical intermediates and end-products.
