This issue of ACS Applied Materials & Interfaces features a forum that is focused on Biomedical Applications of Colloidal Photoluminescent (PL) Quantum Dots (QDs). The development of PL QDs for molecular diagnostics to allow treatment at early stages of the evolution of diseases has been an attractive research area eliciting considerable efforts from a broad spectrum of researchers including inorganic and organic chemists, physicists, engineers, biologists, and medical doctors, Via a multidisciplinary approach with notable and well-appreciated cooperation, this area of research has been advancing slowly but steadily, overcoming challenges in the synthesis of strongly luminescent QDs with enhanced synthetic reproducibility and particle yield at low temperature, and in surface modification such as bioconjugation for targets of interest and for improved detection sensitivity.
