Abstract
The invention generally provides systems and methods for particle detection for minimizing microbial growth and cross-contamination in manufacturing environments requiring low levels of microbes, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products, such as sterile medicinal products. In some embodiments, systems of the invention incorporate a housing having an outer surface being a first antimicrobial surface and a touchscreen being a second antimicrobial surface. In some embodiments, substantially all of the outer surfaces of the system are antimicrobial surfaces. In some embodiments, the first antimicrobial surface may comprise an Active Screen Plasma alloyed layer. In some embodiments, the housing may comprise a molded polymer substrate and a metal coating layer bonded to the molded polymer substrate such that at least some exterior surfaces of the housing are metal coated surfaces.
