Latest Patents

Foster's pivotal patent, titled "Supercritical Fluid Sterilization Method," addresses the challenges of sterilizing materials, particularly polymers used in medical applications. The method utilizes supercritical fluid carbon dioxide, treated under precise conditions of pressure ranging from 2000 to 3000 psi (140 to 210 bar) and temperatures between 30 and 45 degrees Celsius. This process typically spans periods of 20 minutes to six hours, with optimal results achieved in 0.5 to 2 hours. The method’s effectiveness is enhanced by agitation, pressure cycling, and the presence of water, which improves the diffusion of supercritical fluid carbon dioxide into microbial cells, altering their internal pH and leading to cell death.
