Abstract

ZnO nanoparticles show a big potential as a fluorescent probes in biological fields, such as bioimaging, biolabeling and biodetection because of their unique optical properties. However, their surface modification is necessary for application in biosystems. We prepared 40–50 nm ZnO nanoparticles functionalized with thioglycolic acid (TGA) for applications in biosystems. The capping with the thiol acid was confirmed by zeta potential measurements and FT-IR spectroscopy. UV-vis and photoluminescence spectroscopies confirmed the effect of modification as well.
