Stem cell transplantation is currently implemented clinically but is limited by low retention and engraftment of transplanted cells and the adverse effects of inflammation and immunoreaction when allogeneic or xenogeneic cells are used. Here, we demonstrate the safety and efficacy of encapsulating human cardiac stem cells (hCSCs) in thermosensitive poly(N-isopropylacrylamine-co-acrylic acid) or...
Microgel particles of cross-linked poly(NIPAM-co-acrylic acid) with different acrylic acid contents are investigated in solution and in the adsorbed state. As a substrate, silicon with a poly(allylamine hydrochloride) (PAH) coating is used. The temperature dependence of the deswelling of the microgel particles was probed with atomic force microscopy (AFM). The inner structure of the adsorbed mi...
Gold nanoparticles (*40 nm in diameter) were encapsulated by a hydrogel overlayer generated by the free radical polymerization of N-isopropylacrylamide-co-acrylic acid (NIPAM-co-AA), which was promoted by a specifically designed radical initiator covalently anchored to the surface of the gold core. The size and morphology of the shell/core nanoparticles were characterized by scanning electron m...
The preparation of different carbon-shell morphology microspheres and controllable surface area via using thermoplastic polymers as carbon source was still a challenge. In addition, the unique structure porous Silica@Carbon (Sil@C) not only can provide larger active site, but also have characteristics high mechanical strength easy modification. Herein, we report simple method to in-situ fixatio...
