ZnO metal oxide nanoparticle as biological tool

Inorganic metal oxide ZnO in the form of nano particles can change the way diseases are diagnosed and treated. ZnO Nps are selective in targeting cancer cells and due to its nano size can enter into cells and destroy it. Drugs, fluorescent agents (for imaging), targeting agents (to target diseased cells only) etc. be loaded on ZnO Nps to deliver drugs selectively in a controlled manner to specific site. ZnO Nps is non toxic as declared by medical community and hence can replace the inaccuracy and harmful side effects of conventional medicine in bulk form. In this review we have discussed about the preparation and characterization of ZnO Nps. Later part concentrated on applications in various fields including biomedical field.

Automated summary

Inorganic metal oxide ZnO in the form of nano particles has the potential to revolutionize the diagnosis and treatment of diseases. ZnO Nps can selectively target cancer cells and destroy them due to their nano size. They can also be loaded with drugs, fluorescent agents, targeting agents, etc. to deliver drugs to specific sites in a controlled manner. ZnO Nps are declared non-toxic by the medical community, making them a safer alternative to conventional medicine.
