Abstract
A team of physicists and biologists at Rockefeller University in the US have produced biocompatible quantum dots and used them to image a live frog embryo. Inorganic semiconductor quantum dots are brighter, live longer than organic fluorophores and have a broader excitation spectrum. The researchers found that an individual hydrophobic quantum dot could be encapsulated in a micelle made from two kinds of phospholipids. Hence without subjecting the particles to any surface modifications they were able to prevent the quantum dots from coming in direct contact with the aqueous biological environment.
