Quantum Dots News and Research

RSS

A quantum dot is a semiconductor whose excitons are confined in all three spatial dimensions. As a result, they have properties that are between those of bulk semiconductors and those of discrete molecules.

Self-illuminating quantum dots for in vivo imaging

Quantum dots have already proven themselves as powerful imaging probes that can enable researchers to track disease-related molecules inside cells and even within the body.
