Structural and Optical Characteristics of Cu Doped Sno2 Nanostructures

Metal oxide nanoparticles have wide applications, primarily in the technology field, including their use as a semiconductor, electroluminescent or thermoelectric material, but they are also used in biomedical applications as drug delivery systems for treatment and diagnosis and in environmental decontamination applications. The classical methods for obtaining metal oxide nanoparticles are based on chemical and physical techniques that employ hazardous and expensive chemicals with high energy input and a negative effect on the environment. The production of metal oxide nanoparticles via biogenic synthesis has received increasing attention recently because it is a novel process for the development of engineered materials. Biogenic SnO2 nanoparticles demonstrated antibacterial activity against E. coli and antioxidant properties, as assayed by scavenging the free radical of 2, 2-diphenyl-1-picrylhydrazyl hydrate [1]. These particles demonstrate biomedical applications. Cu concentration on the SnO2 affects the sensibility which is not investigated as Nano sensor in the literature.
