TL;DR: It is proved that control of plasma nanotexture can be achieved by carefully choosing the reactor wall material and X-ray photoelectron spectroscopy is used to study the surface chemical modification in the plasma.

TL;DR: This work demonstrates a mass-production-amenable technology for fabrication, surface modification and multifunction integration in polymeric microfluidic devices, namely direct lithography on the polymeric substrate followed by polymer plasma etching, and selective plasma deposition.

TL;DR: In this paper, the authors describe how plasma-wall interactions in etching plasmas lead to either random roughening/nanotexturing of polymeric and silicon surfaces, or formation of organized nanostructures on such surfaces.

TL;DR: In this article, the authors showed that with increasing plasma treatment duration, roughness increased while periodicity decreased, resulting in surfaces of enhanced surface area exploited for the enhancement and control of surface hydrophobicity when followed by Fluorocarbon (FC) film coating of the PDMS surface.

TL;DR: A sample preparation module comprising bacteria cell capture and thermal lysis on-chip with potential applications in food sample pathogen analysis and excellent selectivity was obtained in a sample containing S. Typhimurium and E. coli bacteria.
