Peptide-Mediated Cellular Delivery of Semiconductor Quantum Dots

Gemmill K., Delehanty J., Stewart M., Susumu K., Oh E., Deschamps J., Blanco-Canosa J., Dawson P., Huston A., Medintz I., US Naval Research Laboratory, US

Semiconductor CdSe/Zn quantum dots are ideal materials for biological imaging due to their superior optical properties over fluorescent proteins and organic dyes. However, cytosolic cellular delivery of quantum dots has been hindered by endosomal sequestration [...]

Chip-Based Energy Transfer System between Quantum dots and Gold Nanoparticles for Analysis of Protein Glycosylation

Kim H-S, Kim Y.P., Park S., Oh E., Oh Y.H., Oh E., Oh Y.H., Kim H-S, Kim Y.P., KAIST, KR

Protein glycosylation is one of the most essential processes in the living systems, and often is a major target for developing therapeutics and diagnosis. We have developed a chip-based energy transfer system between quantum dot [...]

Fast and Easy Detection System of Protein Glycosylation by Using Resonant Energy Transfer between Nanoparticles

Oh E., Lee D., Kim H-S, Korea Advanced Institute of Science and Technology, KR

We construct the new glycosylation detection system using Resonance Energy Transfer (RET) between gold nanoparticles (AuNPs) and semiconductor quantum dots (QDs). RET can be induced by biomolecular interactions between concanavalin A (conA)-conjugated AuNP (conA-AuNP) as [...]
