PATTERNED HIERARCHICAL OMNIPHOBIC STRUCTURES FOR ANTI-FOULING AND BIOSENSING APPLICATIONS

Thrombosis on medical devices and surface blood contamination are undesirable and can be eliminated by utilizing repellant surfaces. For this end, we report an easily scalable, all solution-based surface modification, based on nanoparticle deposition and heat-induced thin film wrinkling. Also in a facile approach, the repellency was tested in a transient microfluidics system. Furthermore, dual superhydrophobic and hydrophilic properties in patterns were added, leading to selective digitization of droplets with a single dipping method for high-throughput biosensing.
