Paper Abstract

The interface of targeting molecules that can recognize and identify specific biomolecules with highly luminescent semiconductor nanocrystals or quantum dots can lead to a novel and powerful new class of probes for studying biomolecules in real-time or for imaging and detecting diseases. We describe the rationale design of optical nanoprobes by using fluorescent semiconductor quantum dots with targeting molecules (TMs)-identified using phage display screening. Quantum dots are nanometer-sized particles with unique and tunable optical properties. They offer numerous optical advantages over traditional organic fluorophores in biological analysis and detection (e.g., photostability, continuous absorption profile).
