Abstract. Active control of droplet mobility through low cost tools is highly desirable in applications entailing microfluidics, Lab-on-Chip devices and pertinent technologies. Here, we present the design concepts of a versatile, low cost tool for dynamic droplet mobility manipulation, employing a scheme with backpressure application. Initially sticky open-or closed-channel fluidics with hydrophobic, porous walls are rendered slippery with the application of backpressure through the porous walls. Deliberate control of backpressure directs the wetting phenomena to the desired state. Operation parameters, and control system considerations are presented. Ultra-low backpressure values, are needed for channels with small cross-sections, which in turn are compatible with ultra-low energy demands.

“…This observation is sound with effects reported in appropriate literature. Namely, many authors have shown that a treatment of organic materials with gaseous plasma leads to increased surface roughness [77,[81][82][83]. While the effect is not yet fully understood, a plausible explanation is selective interaction with amorphous and crystalline segments of cellulose materials.…”

IntroductionThe aim of this mini review was zoom in the perspective and feasible methods to produce nanopatterned polymers surfaces and to collect their some properties. This has opened new possibilities for making affordable polymer products with functional nanopatterned surfaces.While a variety of approaches to create hydrophobic/ superhydrophobic surfaces have been developed, [1][2][3][4][5] there are still restrictions on their widespread use due to the cost, number of processing steps, limits on the manufacturable area, durability, instrumentation required, etc. This has led to the development of inexpensive and reliable techniques for the commercial production of hydrophobic layers. Electrochemical methods have been used to prepare a Ni based nanostructured surface coupled with a polydimethylsiloxane (PDMS) monolayer using spin -coating. 6 The surface hydrophobicity increased by about 30% in comparison to the Ni surface only and could be modified to enhance the adhesion of ordered biomolecules or the self-assembly of monolayers. Alternative simple methods included the fabrication of a shark-skin-like patterned PDMS modified with carbon nanotubes to form a polymeric superhydrophobic film.7 A high viscosity paste (comprised of 10 wt % multi walled carbon nanotubes dispersed into PDMS) was placed between two rollers, and the paste was transferred as a smooth film (with less than 300nm roughness) onto the roll with the high rotational speed.7 A spin-coating method has been used to form a biomimetic interface from melanin whose electric signal transduction can be modified.8 High density plasma processing was employed to create a nanotextured superhydrophobic transparent poly (methyl methacrylate) surface. 9 By appropriate tuning of the plasma conditions, either random or ordered hierarchical structures of high aspect ratio and surface area could be reproducibly created. Such plasma treated polymeric surfaces have been evaluated as substrates for efficiently controlling the wettability, biomolecules immobilization, and cell adhesion of the surface, paving the way to a wide spectrum of applications. A three-dimensional plasma micro-nanotextured cyclo-olefin-polymer surfaces has been used for biomolecules immobilization because of its environmentally stable superhydrophobic and superoleophobic properties.10 Plasmas could also be used to deposit fluorocarbons on a cyclo-olefin polymer to enhance hydrophobicity 11 with good adhesion and effective surface protection reducing plastic deformation. A micro reactive ion-etching method has been used to prepare nanotextured films from PDMS for enhanced cancer cell isolation. 12Slippery liquid-infused porous surfaces show great promise for preventing biofilm formation owing to their low surface energy in combination with their self-cleaning properties. 13 Li and co-workers demonstrated a novel hydrophobic liquid-infused porous poly (butyl methacrylate-co-ethylene dimethacrylate) surface with bacteriaresistance in BM2 mineral, which had medium and long-term stability in aque...
