The semiconductor nanocrystals known as quantum dots (QDs) have become a potential candidate for next generation fluorophores. Attention in QDs research is focussed on a wide range of applications like sensor, photovoltaic cells, catalysis, biolabelling, early cancer detection, etc. The unique morphology, tunable optical properties, photostability and flexibility for surface modification by biomolecules of QDs has provoked the scientific community to unravel many problems in biological processes. In view of these scientifically advantageous and distinguishable characteristics of QDs, an overview of research on the interaction of Cadmium telluride QDs with biomolecules and bioimaging applications and limitations of QDs is presented in this chapter.
