Quantum Dots in Biology

Quantum dots are tiny semiconductor particles, only a few nanometers in size, that can emit bright, specific colors when exposed to light. In biology, they are used as highly precise markers to track and visualize molecules, cells, or tissues. Because their light emission is stable and tunable, quantum dots enable detailed imaging and diagnosis at the molecular level, aiding in medical research and diagnostics without fading or losing signal, unlike traditional dyes. This makes them powerful tools for understanding biological processes with high sensitivity and accuracy.
