    • A delivery system for delivering an anti-microbial agent to a surface in a time release manner. The delivery system includes one or more polymeric particles (e.g., microspheres, core/shell particles, latexes, porogens, cryogenically ground beads, condensation polymer particles, flakes, etc.) and at least anti-microbial agent attached thereto. The anti-microbial agents may or may not be soluble in the polymeric particle or in the monomeric precursor used to make the polymeric particle. The anti-microbial agent can be incorporated into the microsphere using either a post polymerization addition process or an in situ addition process. The delivery system can be fashioned to provide characteristics that are application specific. Examples of such delivery systems include but are not limited to substrates (such as tapes, sheets of material and the like) coated with the releasably loaded polymeric particles, sprayable dispersions or suspensions of these polymeric particles and the like.
    • 用于以时间释放方式将抗菌剂递送到表面的递送系统。 递送系统包括一种或多种聚合物颗粒(例如,微球,核/壳颗粒,胶乳,致孔剂,低温研磨珠,缩聚物颗粒,薄片等)和至少与其连接的抗微生物剂。 抗微生物剂可以或可以不溶于聚合物颗粒或用于制备聚合物颗粒的单体前体中。 可以使用后聚合加成方法或原位添加方法将抗微生物剂并入微球。 传送系统可以被设计成提供特定于应用的特征。 这种递送系统的实例包括但不限于涂覆有可释放负载的聚合物颗粒,这些聚合物颗粒的可喷雾分散体或悬浮液等的基材(例如胶带,材料片等)。
