摘　　要：We demonstrate that a recently developed coating composed of superhydrophobic silicone nanofilaments can be selectively functionalized to yield well defined micron-scale patterns of contrasting wettabilities(superhydrophobic/hydrophilic and amphiphobic/amphiphilic).Nanofilament ablation was performed using a near-ultraviolet(UV)laser with a wavelength of 355 nm and a repetition rate of 10 kHz.This is a highly promising approach for open channel microfluidics and microarray analysis due to its simplicity,the chemical and environmental stability of the coating,and the low cost. 关键词：SUPERHYDROPHOBIC ultraviolet(UV)laser ablation WETTABILITY open channels
