Polyol synthesis of silver nanoparticles: mechanism of reduction by alditol bearing polysaccharides.

abstract：:The development of large-scale suspension cell cultures using microcarriers has long been a focus of attention in the fields of pharmacy and biotechnology. Previously, we developed cell-detachable microcarriers based on temperature-responsive poly(N-isopropylacrylamide) (PIPAAm)-grafted beads, on which adhering cells ...
