Recent Advances in the Use of Cadmiumfree Quantum Dots for Bioimaging

Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
