Silica-shelled single quantum dot micelles

David Shenkenberg

Quantum dots might become more widely used in biological applications if better methods for making them water-soluble were available. Chemically coating quantum dots to improve their water solubility often makes them so large that they interfere with Förster resonance energy transfer or normal cellular processes. Silica-coated quantum dots are small and have a high surface area and a large pore size, the latter of which may be useful for biosensing and photodynamic therapy (PDT). However, silica coating often yields quantum dots that quench fluorescence because they aggregate,...Read full article
