    • A novel gypsum board having improved antimicrobial and antibacterial properties is disclosed. The board comprises a gypsum core, front and back paper facings, and a polymeric antimicrobial or antibacterial compound effective at inhibiting fungal growth. Preferred polymeric antimicrobial and antibacterial compounds include polyDADMAC, polyTMMC, and quaternized polyvinyl pyridine derivatives. The novel gypsum board further comprises a non-polymeric antimicrobial or antibacterial compound. Preferred non-polymeric antimicrobial or antibacteral compounds include cetyl pyridinium chloride and sodium pyrithione. The polymeric antimicrobial or antibacterial compound can be present in the gypsum core and/or on one or both of the paper facings. The non-polymeric antimicrobial or antibacterial compound may be encapsulated in a material or ionically associated with the polymeric antimicrobial or antibacterial compound to allow releases of the non-polymeric antimicrobial or antibacterial compound over time and/or upon exposure to moisture. Methods for preparing the aforementioned novel gypsum board are also disclosed.

    • This invention relates to antimicrobial wound dressings having a non-leaching antimicrobial activity, releasable antimicrobial and antiprotease agents, and a controlled-release bioactive agent such as doxycycline. The Wound dressing material is absorbent and acts as a substrate for antimicrobial and antiprotease agents as well as bioactive agents. More generally, this invention relates to methods and compositions for materials having a non-leaching coating that has antimicrobial properties. The coating is applied to substrates such as gauze-type wound dressings, powders and other substrates. Covalent, non-leaching, non-hydrolyzable bonds are formed between the substrate and the polymer molecules that form the coating. A high concentration of anti-microbial groups on multi-length polymeric molecules and relatively long average chain lengths, contribute to an absorbent or superabsorbent surface with a high level antimicrobial efficacy. Utilization of non-leaching coatings having a plurality of anionic or cationic sites is used according to this invention to bind a plurality of oppositely charged biologically or chemically active compounds, and to release the bound oppositely charged biologically or chemically active compounds from said substrate over a period of time to achieve desired objectives as diverse as improved wound healing to reduction in body odor.
    • 本发明涉及具有非浸出抗微生物活性的抗微生物伤口敷料,可释放的抗微生物剂和抗蛋白酶试剂,以及控释释放生物活性剂如多西环素。 伤口敷料材料是吸收剂并用作抗微生物剂和抗蛋白酶剂以及生物活性剂的底物。 更一般来说,本发明涉及具有抗菌性能的非浸出涂层的材料的方法和组合物。 将涂层施加到诸如纱布式伤口敷料,粉末和其它底物的基底上。 在底物和形成涂层的聚合物分子之间形成共价,非浸出,不可水解的键。 在多长度聚合物分子上具有高浓度的抗微生物群和相当长的平均链长,有助于具有高水平抗微生物效能的吸收剂或超吸收剂表面。 根据本发明使用具有多个阴离子或阳离子位点的非浸出涂层的使用以结合多个带相反电荷的生物或化学活性化合物,并通过一个或多个阴离子或化学活性化合物从所述底物上释放结合的带相反电荷的生物或化学活性化合物 一段时间以达到预期的目标,如改善伤口愈合以减少体臭。

    • A system and method of enhancing the antimicrobial and biofilm-resistant efficacy of surfaces that have cationic polyelectrolytes nonleachably bound thereto in order to impart antimicrobial activity to the surface. The system for enhancing antimicrobial efficacy involves brushing, dipping, wiping, spraying, or storing the surface in a solution containing citrate ion. The method involves treatment of the surface with a solution which enhances the antimicrobial and biofilm-resistant efficacy of the surface, and which prevents a loss of the antimicrobial properties of the surface which may occur over time. Preferably, the enhancement agent is citrate ion and the cationic polyelectrolyte is poly(diallyldimethylammonium chloride), also known as polyDADMAC. The system is particularly beneficial for surfaces of articles such as contact lenses.
