Elastin like polypeptides (ELPs) are a class of naturally derived and non-immunogenic biomaterials that are widely used in drug delivery and tissue engineering. ELPs undergo temperature-mediated inverse phase transitioning, which allows them to be purified in a relatively simple manner from bacterial expression hosts. Being able to genetically encode ELPs allows for the incorporation of bioactive peptides

Controlling bacterial fouling with polyurethane/N-halamine semi-interpenetrating polymer networks. J. Bioact. Compat. Polym. (IF 1.624) Pub Date : 2017-01-01 Kemao Xiu,Jianchuan Wen,Nuala Porteous,Yuyu Sun
N -halamine-based interpenetrating polymer networks were developed as a simple and effective strategy in the preparation of antimicrobial polymers. An N-halamine monomer, N-chloro-2, 2, 6, 6-tetramethyl-4-piperidyl methacrylate, was incorporated into polyurethane in the presence of a cross-linker and an initiator. Post-polymerization of the monomers led to the formation of polyurethane/N-halamine

Combined Effects of Drugs and Plasticizers on the Properties of Drug Delivery Films. J. Bioact. Compat. Polym. (IF 1.624) Pub Date : 2016-11-09 Cheryl L Jennings,Thomas D Dziubla,David A Puleo
Formation of scar tissue may be reduced or prevented if wounds were locally treated with a combination of molecules tuned to the different healing phases, guiding tissue regeneration along a scar free path. To this end, drug delivery devices made of cellulose acetate phthalate and Pluronic F-127 were loaded with either quercetin or pirfenidone and plasticized with either triethyl citrate (TEC) or tributyl

Influence of conductive PEDOT:PSS in a hard tissue scaffold: In vitro and in vivo study J. Bioact. Compat. Polym. (IF 1.624) Pub Date : 2019-10-19 N Fani; M Hajinasrollah; MH Asghari Vostikolaee; M Baghaban Eslaminejad; F Mashhadiabbas; N Tongas; M Rasoulianboroujeni; A Yadegari; KF Ede; M Tahriri; L Tayebi
The presence of a conductive component in bone scaffolds can be helpful in facilitating the intracellular electrical signaling among cells as well as improving bone healing when electromagnetic stimulation is applied. In this study, poly(3,4-ethylenedioxythiophene): poly(4-styrene sulfonate) as a biocompatible conductive polymer was incorporated into a hard tissue scaffold made of gelatin (Gel) and
