PTG antibacterial biomaterials can reduce the infectivity of medical devices

Berkeley, California, USA news, polymer technology group, an outstanding biomaterial company, announced that Dr. Shanger Wang will make a speech at the 8th World biomaterials conference held in Amsterdam, the Netherlands this week. His speech (alkyl ammonium chloride end group surface active thermoplastic polycarbonate polyurethane: antibacterial activity, foaming and surface properties) includes the description of a biopolymer material that has made breakthrough progress, which has constant antibacterial surface properties in order to reduce the infectivity of core medical devices. PTG was also exhibited at the conference (booth 5). Instrument manufacturing has faced the challenge of producing biopolymer materials with embedded antibacterial surface properties, which are used to reduce the infectivity of core equipment. But so far, closer applications are drug-eluting compounds or coatings, which are ultimately consumed. What is more worth looking forward to is the easily processed biomaterials with good wet strength and long-term performance, instead of containing filterable additives. Please don't open the door of the box, medicaments and biocides. CEO Bob Ward said that we believe we have the answer to this question

indeed, the results presented by Dr. Wang confirmed that a small number of bioactive end groups can be embedded in the synthesis of biopolymers, ward added. After extrusion or molding, this new device can modify its own surface because this new end group has surface activity and self-assembly ability. Antibacterial groups will be enriched on the required surface. For this reason, secondary surface coating or treatment is not necessary. This will increase output in reducing product costs and manufacturing cycles

Dr. Wang will announce that the surface active thermoplastic polyurethane with alkyl ammonium chloride end groups has been successfully synthesized, and their physical properties, surface chemical properties and biological activities have also been greatly evaluated by the development of composites in China in recent years. The existence and self-assembly of terminal groups on the surface are determined by SFG (sum frequency effect spectrum). The polymer shows low water absorption, high strength and processability, high molecular weight and effective contact killing control of Gram-positive bacteria. Therefore, regular inspections should also be carried out. Dr. Wang will also discuss how these modified tpcus (thermoplastic polycarbonate polyurethane) and other antibacterial self-assembled end-based plastics will be optimized by TPG, with a view to being used in more biomedical applications
