“…Open-channel droplet-based microfluidic systems have several benefits compared with conventional closed-channel based microfluidic devices in terms of easy introduction of sample liquid, low sample and energy consumptions, and rapid chemical and biological reactions [155,156,157,158,159,160,161,162,163,164,165]. Manipulation of droplet motions is most important for the open-channel droplet-based microfluidic system.…”

Biological creatures with unique surface wettability have long served as a source of inspiration for scientists and engineers. More specifically, materials exhibiting extreme wetting properties, such as superhydrophilic and superhydrophobic surfaces, have attracted considerable attention because of their potential use in various applications, such as self-cleaning fabrics, anti-fog windows, anti-corrosive coatings, drag-reduction systems, and efficient water transportation. In particular, the engineering of surface wettability by manipulating chemical properties and structure opens emerging biomedical applications ranging from high-throughput cell culture platforms to biomedical devices. This review describes design and fabrication methods for artificial extreme wetting surfaces. Next, we introduce some of the newer and emerging biomedical applications using extreme wetting surfaces. Current challenges and future prospects of the surfaces for potential biomedical applications are also addressed.

“…Polydopamine films have been found promising candidates for the protection against corrosion [13,14], for promoting biomineralization processes [15,16], for the reduction in friction coefficients [17] for many bio-applications [18], for the functionalization of superhydrophobic coatings [19] and the functionalization of microfluidic devices [20]. Such coatings, having a surface composition similar to that of melanin and often called pseudomelanin, can also be easily modified in a single step reaction with molecules containing nucleophilic groups such as amines [21,22] or thiols [1] as well as other chemical functionalities [23], or with metal nanoparticles as silver [24] or gold [25] via the reduction of the corresponding cations dissolved in solution.…”

“…Superhydrophobic coatings can have a significant impact on the development of glass and plastics with self-cleaning [1][2][3][4] and antifogging [5,6] properties, while also adding value to a wide range of tribological [7,8] and microfluidics applications [9,10]. In superhydrophobic coatings, hierarchical roughness introduces multiscale voids and gaps, trapping air at the material-water interface and, in turn, inducing high contact angles ([150°) with water droplets, low contact angle hysteresis and sliding angles.…”

In the present work, superhydrophobic SiO 2 -coated ZnO nanorods have been successfully synthesized on glass surfaces via single-step hydrothermal route involving silicon hydroxide as silicon source, sodium dodecyl sulfate as surfactant and Zinc(II) acetate powder as Zinc source. The morphology and structure of obtained products were characterized by XRD, scanning electron microscopy, TEM, energy dispersive X-ray analysis, Pl and FTIR. The effect of calcination time on morphology and structure of as-synthesized products was evaluated. The obtained results exhibited that the synthesized nanorod-like product by calcining for 4 h showed excellent uniformity and quality. Furthermore, the water contact angel measurements were performed on as-synthesized products. The results showed due to introducing roughness by growth of SiO 2 on ZnO nanorod-like structure, all the samples show excellent degree of hydrophobicity and introducing these products on glass surfaces makes the glass superhydrophobic.
