• Surface Patterning of Self-healing P Copolymer for Dynamic Control Cell Behaviors

    9 days ago - By Springer

    Abstract
    Cell behaviors are regulated by a dynamic and complex environment characterized by biophysical, mechanical and biochemical properties. However, most works regulate cell behaviors under static conditions or by external factors. To control cell adhesion and proliferation with a dynamic and mechanical environment, we pattern the surface on self-healing copolymer P. The copolymer P with the composition of 48/52 recovers nearly 100% of its original tensile strains after 86 h of recovery from deformation. The physical patterns on P film are obtained over large areas and the size of the...

  • Antibacterial and pH-responsive Quaternized Hydroxypropyl Cellulose- g -Poly Graft Copolymer: Synthesis, Characterization and Properties

    9 days ago - By Springer

    Abstract
    The novel quaternized hydroxypropyl cellulose- g -poly graft copolymers, HPC- g -QCP, have been successfully synthesized to combine the properties from hydrophilic hard HPC biomacromolecular backbone and hydrophobic flexible polyether branches. Firstly, the P living chains were synthesized by cationic ring-opening copolymerization of THF with ECH. Secondly, P living chains were grafted onto HPC backbone by reaction with -OH groups along HPC to produce HPC- g -P graft copolymers. Thirdly, the mentioned graft copolymers were quaternized by reaction with ternary amine to generate...
