Different strategies to achieve antibacterial substances
The release strategy of a biologically active agent can be related to a bulk or just a surface mass as in Figure )6( Figure (2-3) shows antibacterial polymers: (a) an antibacterial strategy that is fully demonstrated by the body. (B) The antibacterial efficacy shall be on the surface only. (C) Biocides molecules are released from the polymer base material. (D) release of antibacterial agents released from paint [61].
Also, this strategy can come from polymers that contain biologics active repeat units, which have the potential to inhibit the effect of bacteria during the release of antibacterial agents as in Figure (c). For example, phenicillin V, Cephradine) were associated with the …show more content…

The first common strategy is to bind antibacterial polymers with the surface. This is done either by chemical inoculation or by layer deposition or polymerization [61]. It was found that different positive ions have polycations possessing antibacterial properties on the assumption that they either interact with cell walls or rupture the cell membrane. For example, poly (4-vinyl-N-alkyl pyridinium bromide) is a positive polycation. Was covalently associated with a glass slide to create a surface that had the ability to kill bacteria during direct contact …show more content…

Bacteria spread rapidly through contact with the surface or through plastic catheter tubes for example about 80% - 95% of infections in the hospital are urinary tract infections[76][77]. This has led to the growth of the polymer market, especially polyolefin-based polymers such as polypropylene and polyethylene used in health care applications. This growth is due to polymer properties such as chemical properties, radiation, heat resistance, hardness, transparency, gas, fluid, shock, elasticity, low or medium cost tolerances[78].
2.11 Requirements of nanomaterials
The use of nanomaterials in medical applications must possess exceptional and notable properties where they can be designed to address medical application issues. For example, medical nanomaterials should not be destructive to living tissue, unable to cause cancer, resist corrosion, and have low toxicity [79]. Materials must be able to resist disinfection by gamma rays and steam sterilization. In polymeric biomaterials, the structure and structure of molecular chains controls mechanical properties, for example, high-density polyethylene is used as a loading surface for knee replacement [80][81].
