Effect of texture of platelet bags on bacterial and platelet adhesion.

Background: Missed detection of Staphylococcus epidermidis contamination in platelet (PLT) storage bags by the standard 24-hour-postcollection BacT/ALERT screening test has been documented. A slow growth rate and the strong tendency of this bacterium to adhere to surfaces can contribute to missed detection of the pathogen.

Study Design And Methods: Topography of two different PLT storage bag surfaces, textured (rough) and smooth surfaces of Terumo 80440 bags (designated A15), was studied.

Effect of Extreme Wettability on Platelet Adhesion on Metallic Implants: From Superhydrophilicity to Superhydrophobicity.

In order to design antithrombotic implants, the effect of extreme wettability (superhydrophilicity to superhydrophobicity) on the biocompatibility of the metallic substrates (stainless steel and titanium) was investigated. The wettability of the surface was altered by chemical treatments and laser ablation methods. The chemical treatments generated different functionality groups and chemical composition as evident from XPS analysis.
