- W4220710446 abstract "Multi-arm star polymers with controlled molecular architecture suitable to be used as biomaterials are rapidly developing area of research. Herein, G2 and G3 polyurethane dendrimers containing bio-active bis-indolyl building blocks were converted into corresponding multifunctional ATRP initiators via a single-step reaction and characterized thoroughly. Polymerization of 2-hydroxethyl methacrylate (HEMA) monomer for different time duration using these initiators and CuBr/2,2′-bpy ATRP system yielded star PHEMAs with molecular weight (Mn) in the range of 2.79 × 104 – 4.52 × 105 g mol−1; the poly dispersity indices were in the range of 1.16–1.49. Glass transition temperature of these star PHEMAs was found significantly low compared to the linear PHEMA. Contact angle measurements carried out on the surface of polyethylene terephthalate (PET) film coated with these polymers confirmed that these polymers are more hydrophilic compared to the un-coated PET surface. The integrated anti-fouling and anti-bacterial properties of these polymer coatings were studied with two common pathogens namely E. coli and P. aeruginosa and found that the binding of both of these bacterial cells either in live or dead form was negligibly low in the polymer coated PET surface compared to un-coated films and also found that the percentage of live cells was low compared to dead cells." @default.
