VitroStealth is a non-biofouling (NBF) coating technology. The coating is scratch resistant and reduces unwanted protein absorption and cellular adhesion on surfaces. Application includes pre-analytical blood collection devices where VitroStealth coating eliminates surface mediated hemolysis and leads to clean, reproducible and thus reliable serum or plasma samples for the clinical laboratory. In diagnostics, the coating increases signal to noise ratio as the analyte is not partially lost by adsorption to the surface of the device. Furthermore, due to its highly hydrophilic character the coating increases the capillary flow of analytes in micro-fluidic point of care devices. DSM Biomedical, Geleen, The Netherlands,
