摘要： Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.

摘要： Methods and devices are provided for pretreatment of a sample containing microbial cells. In some embodiments, the pretreatment of the sample is performed via the initial selective lysis, within a sample pretreatment vessel, of non-microbial cells (such as blood cells) and the subsequent centrifugal separation of the sample to remove the resulting debris and concentrate the microbial cells. An immiscible and dense cushioning liquid may be included for collecting the microbial cells adjacent to the liquid interface formed by the cushioning liquid upon centrifugation of the pretreatment vessel. After removal of a substantial quantity of the supernatant, resuspension of the collected microbial cells, and re-establishment of the cushioning liquid interface, at least a portion of the remaining suspension may be removed without substantially removing the cushioning liquid. One or more intermediate wash cycles may be performed prior to extraction of the remaining suspension, which provides a “pretreated” sample.
