A composition including a monomolecular layer of the water-soluble photo-activatable polymer and a matrix having at least one carbon, wherein the monomolecular layer is covalently attached to the matrix by a covalent bond between the photo-activatable group and the at least one carbon. The composition further includes a biomaterial having a plurality of active groups, wherein the biomaterial is covalently attached to the monomolecular layer by covalent bonding between the active groups and reactive groups. Also provided is a method for delivery of a biomaterial to a cell.Type: ApplicationFiled: December 8, 2009Publication date: August 19, 2010Applicant: The Children's Hospital of PhiladelphiaInventors: Ivan Alferiev, Ilia Fishbein, Michael Chorny, Robert J.

Publication number: 20090198011Abstract: A flame retardant polymer composition and a process for making the composition are provided. The flame retardant polymer composition is a poly(trimethylene terephthalate) co-polymer containing a trimethylene terephthalate monomer and a phosphorous containing flame retardant monomer. The flame retardant polymer composition is produced by a process in which the trimethylene terephthalate monomer or its precursors and the phosphorous containing flame retardant monomer or its precursors are combined to form the poly(trimethylene terephthalate) co-polymer in one or more pre-polymerization and polymerization steps.Type: ApplicationFiled: December 16, 2008Publication date: August 6, 2009Inventors: Kailash DANGAYACH, Hoe Hin Chuah
