Minimizing Nonspecific Cellular Binding of Quantum Dots with Hydroxyl-Derivatized Surface Coatings
Posted: Fri., March. 7, 2008

Quantum-dot (QD) nanocrystals are promising fluorescent probes for multiplexed staining assays in biological applications. However, nonspecific QD binding to cellular membranes and proteins remains a limiting factor in
detection sensitivity and specificity. Here we report a new class of hydroxyl (-OH)-coated QDs for minimizing nonspecific cellular binding and for overcoming the bulky size problems encountered with previous surface coatings.....More Info

We report a method for single-molecule detection and biomolecular
structural mapping based on dual-color imaging and automated
colocalization of bioconjugated nanoparticle probes....More Info

Gold Nanoparticle Probes May Allow Earlier Cancer Detection
Posted: Thurs., Jan. 17, 2008

Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively....More Info
