Researchers attached titanium dioxide nanoparticles to biomolecules to be able to therapeutically target brain cancer cells without harming normal tissue. It is an example of amalgamation between nanoscience and biological interface, which can be used for biomedical application as commented by Elena Rozhkova of ANL Centre for Nanoscale Materials, USA. The tests have been conducted on preclinical lab models of brain tumors and result showed an almost 100 percent cancer cell toxicity rate after six hours of illumination and 80 percent after 48 hours. A proof of concept is demonstrated, and other cancers can be treated as well using different targeting molecules.
