Our ambition is to provide guidelines for the safe use, disposal, and green technologies for the reuse of nanoparticles. The nanoparticles, like oxide and titania, are used in modern technologies such as medical nanotheranostic platforms, cosmetics, photovoltaic systems, and fuel cells. While much research has been conducted on the biocompatibility of nanoparticles used in biomedicine, the potential impact of waste nanoparticles on the environment is not well understood. Nanoparticles are highly reactive, making them useful in catalysis, but, at the same time, they are also less chemically stable than larger particles. Therefore, nanoparticles react and decompose faster at given conditions than their bulk counterparts. To create stable core-shell nanoparticles, we will investigate how transition-metal oxides, such as titania and ferrites, interact with known complexants. We will exploit the coordinative interaction between the surface metals and complexants. We will also examine how nanoparticles interact with natural complexants, like lignins, tannins, humic acids, and phosphate-based fertilizers. Using natural complexants from biomass, we will explore green technology and their reuse. Our research will help us understand the environmental impact of nanoparticles and develop environmentally friendly nanomaterials for safe use, disposal, or reuse.
