Quantum Dots Pose Minimal Impact to Cells

Abstract:
Nano-sized fluorescent probes that can slip inside living cells and elucidate life’s most fundamental processes, or track the effectiveness of cancer-fighting drugs, are barely noticed by the cells they enter, according to a team of researchers led by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).

This finding should quell concerns that the mere presence of these promising but potentially toxic sentinels disrupts a cell’s function, confounding quantum dots’ ability to accurately track cellular processes or monitor the effectiveness of pharmaceuticals.
