Protein Adsorption on Hybrids of Thermoresponsive Polymers and Single-Walled Carbon Nanotubes

International Journal of Polymer Science, 2016
Poly(N-isopropylacrylamide) (PNIPAAm) is one of the most popular thermoresponsive polymers. Adsorption of RecA proteins onto hybrids of PNIPAAm and single-walled carbon nanotubes (SWNTs) was observed in the presence and absence of DNA molecules. Although

Suspension Culture of Mammalian Cells Using Thermosensitive Microcarrier that Allows Cell Detachment without Proteolytic Enzyme Treatment

Cell Transplantation, 2010
Microcarriers are used to expand anchorage-dependent cells in large-scale suspension bioreactors. Proteolytic enzyme treatment is necessary to detach cells cultured on microcarriers for cell harvest or scale-up, but the enzyme treatment damages the cells

Construction and property characterization of PNIPAAm-grafted chitosan/sodium alginate composite Thermo-responsive hydrogel films

Food Chemistry: X
A series of thermo-responsive PNIPAAm-CS/SA composite hydrogel films were synthesized via radical polymerization and ionic cross-linking. FTIR, XPS, and NMR confirmed the successful covalent grafting of PNIPAAm onto the chitosan (CS) backbone.
