Multifunctional QDs for Molecular Imaging and siRNA Delivery

Open Access Open Access

Abstract

Metal and semiconductor nanoparticles in the 1-50 nm size range are of considerable current interest, not only because of their unique size-dependent properties but also their dimensional similarities with biological macromolecules (e.g., nucleic acids and proteins). These similarities could allow an integration of nanotechnology and biology, leading to major advances in medical diagnostics, prognostics, and targeted therapeutics. In this talk, I present recent development of multifunctional quantum dots for ultrasensitive detections, molecular imaging, and traceable drug delivery.
