"Instrument manufacture has faced the challenge of producing biopolymer materials with embedded antimicrobial surface properties that are used to reduce the infectivity of core equipment. But so far, the closer applications are drug eluting compounds or coatings that are eventually What is more desirable is the easy-to-process biomaterials that have good wet strength and long-lasting properties, but not filterable additives, pharmaceuticals and biocides,†said CEO Bob Ward, “we believe We already have the answer to this question."
"Indeed, the results demonstrated by Dr. Wang confirmed that a small number of biologically active end groups can be embedded during the synthesis of biopolymer materials," Ward added. "After extrusion or molding, this new device can 'modify its own surface' because this new end group is surface-active and self-assembling. Antibacterial groups will concentrate on the desired surface. For this reason, Secondary surface coatings or treatments are not necessary. This will increase productivity in colleagues who reduce product costs and manufacturing cycles."
Dr. Wang will announce the successful synthesis of alkyl ammonium chloride-terminated surface-active thermoplastic polyurethanes. Their physical properties, surface chemistry and biological activity have also been evaluated. The presence and self-assembly of the end groups on the surface is determined by SFG (Simultaneous Frequency Spectroscopy). The polymer exhibits low water absorption, high strength and processability, high molecular weight, and effective control of contact killing of gram-positive bacteria. Dr. Wang will also discuss how these modified TPCUs (thermoplastic polycarbonate urethanes) and other antimicrobial self-assembled end-group plastics will be optimized by TPG for use in more biomedical applications.
