Near-Infrared Light-Responsive Intracellular Drug and siRNA Release Using Au Nanoensembles with Oligonucleotide-Capped Silica Shell



original image

Taking advantage of the character of Au nanorods (NRs) to absorb NIR light, a NIR-responsive oligonucleotide-gated ensemble is developed to perform intracellular drug delivery. Using an oligonucleotide bio-gate enables siRNA release into cells for translational regulation as well as cytotoxicity in anti-cancer drug delivery.
