A quickly tunable wettability pattern plays an important role in regulating the surface behavior of liquids. Light irradiation can effectively control the pattern to achieve a specific wettability pattern on the photoresponsive material. However, metal oxide materials based on light adjustable wettability have a low regulation efficiency. In this paper, zinc (Zn) superhydrophobic surfaces can be obtained by femtosecond-laser-ablated microholes. Owing to ultraviolet (UV) irradiation increasing the surface energy of Zn and heating water temperature decreasing the surface energy of water, the wettability of Zn can be quickly tuned photothermally. Then, the Zn superhydrophobic surfaces can be restored by heating in the dark. Moreover, by tuning the pattern of UV irradiation, a specific wettability pattern can be transferred by the Zn microholes, which has a potential application value in the field of new location-controlled micro-/nanofluidic devices, such as microreactors and lab-on-chip devices.

Photomasks are used as stencil to print images on semiconductor material. This study represents design and specifications of photomask for microfluidic fabrication. For a precise pattern transfer, the photomask should meet with certain considerations such as critical dimension uniformity, resolution and alignment. This paper explains the design of microfluidics with three channels using AutoCAD software for lab-on-chip application. Total surface area of the device is 242.52mm2 in which the width and length is 12.00mm and 20.21mm respectively. The device was designed in particular size to meet its behavior as a disposable chip and increases the economic value when it is fabricated.

Hybrid microfluidic and nanofluidic devices have recently been developed for a variety of applications including water desalination, molecular gates, and other lab-on-chip uses. In this paper, we report on a 2-step wet etch process to fabricate hybrid microfluidic and nanofluidic devices with controllable features including a sloped nanochannel. The nanochannels with slit-like geometry can be fabricated with dimensions as small as 50 nm depth and a width of 30 μm for a minimum aspect ratio of 0.002. The channels are several cm long.
