A dual-functional supramolecular hydrogel based on a spiropyran–galactose conjugate for target-mediated and light-controlled delivery of microRNA into cells†
Abstract
A supramolecular hydrogel formed by spiropyran conjugated galactose was developed for light-controlled release of miR-122 and target-mediated delivery of the miRNA into HepG2 cells cultured on top of the gel.
