Hydrogel nanoparticles (HNP) are an emerging tool of biomedicine with unique materials characteristics, scope, and utility. These hydrated, soft colloidal carriers can penetrate through voids with dimensions narrower than the size of the particle, provide stabilization for fragile biological cargo and allow diffusion and exchange of solutes with external(More)
We report on the assembly of multi-layered polyelectrolyte thin films containing an immobilized enzyme to perform conversion of externally administered prodrugs and achieve delivery of the resulting therapeutics to adhering cells. Towards this goal, multi-layered coatings were assembled using poly(sodium styrene sulfonate) and poly(allylamine(More)
