TKPEI-Ce6
Delivery StrategyTKPEI-Ce6 is a red-light-activated siRNA delivery harness built from chlorin e6-conjugated, thioketal-cross-linked polyethylenimine that condenses siRNA into nanoscale complexes. Upon 660 nm irradiation, it generates reactive oxygen species and undergoes thioketal-linked nanostructure disruption, promoting endosomal escape and cytosolic siRNA release for gene silencing.
