Cadmium selenide quantum dots and its biomedical applications

The focus of the present review is to provide a detailed discussion about the outstanding properties, namely physical, optical (majorly quantum confinement phenomenon), and electrical of cadmium selenide quantum dots (CdSe QDs). CdSe QDs have extensive utility in the biomedical domain owing to their unique properties. Thus, this review illustrates the wide range of applications of CdSe QDs in optical features, such as targeted drug delivery, drug resistance, drug analysis, photo-thermal therapy, antimicrobial activity, and tissue staining. Moreover, this review also highlights by discussing about the optical and optoelectronic application, which includes a good display, lasing, light emitting diode, and bioimaging that requires elevated photoluminescence spectra, quantum yield, and photostability.
