Intracellular Delivery of Small Molecule Reactive Ligands for Bioconjugation
A protected small molecule probe is delivered intracellularly and subsequently releases an aryl diazonium ion for use as a bioconjugation agent or drug delivery agent. This technology enables a novel chemical probe for observing intact biological cells. It builds on previous IP developed by Jewett laboratory for protection, as a class of chemistry enabling...
