Abstract: A novel class of mixed micelles formed with critical micelle concentration (Cmc) character's diblock copolymer, and temperature-sensitive character's diblock copolymer were disclosed. The mixed micelles possess complementary effects in adjusting external temperature shift (storage vs. body temperature) and concentration change (dilution after intravenous injection). The mixed micelles of the present invention can serve as a potential injectable drug delivery system for anticancer drugs, such as doxorubicin and many others.

Abstract: The present invention discloses a filter medium for removing leukocytes from a leukocyte-containing sample, comprising: a substrate and a first polymer.

Abstract: The present invention provides a lambda-shaped carbazole based chromophore, and a main-chain NLO polyurethane containing the same. The lambda-shaped structure reduces the plasticization to the main-chain polymers caused by the chromophore and increases temporal stability of the NLO coefficients of the main-chain NLO polyurethane. The NLO coefficients of the main-chain NLO polyurethane are stable because the efficiency of dipole alignment in electric field is increased due to the dipole thereof being perpendicular to the main chain of the polyurethane.

Abstract: This invention is a heterobifunctional artificial cornea or biomedical membrane and novel process for preparing the heterobifunctional artificial cornea. In this method, plasma induced graft polymerization is adopted to provide the surface property modification of polymer materials like silicone or polyurethane. At first, the frontal side of the material is grafted with polyacrylic acid or polymethacrylic acid and then bonded with collagen, or 2-hydroxyethylmethacrylate (HEMA) is grafted alone. A surface which increases the cell attachment and growth can be then developed. Another side of this membrane is grafted with acrylic acid or polymethacrylic acid and then different molecular weights of polyethylene oxide (PEO) is bonded thereto. 2-methacryloyl-oxyethyl phosphoryl chloride (2-MPC) is grafted to the membrane.
