This work has been undertaken to study the microfluidic chip made by the excimer laser ablation. A Kind of Micro electrophoresis chip, Micro polymer chain reaction (PCR) and combined with electrochemical detection and micro blood separator are made using the commercial Polyimide film (Kapton from Dupont). The surface characterization of the excimer-ablated polymide is studied by using the Scanning Electron Microscopy (SEM), Atomic Force Microscope (AFM) and X-ray photoelectronic spectroscopy (XPS). The surface roughness is also measured by white light interference microscope (Wyco NT8000, Vecco. Com, USA). A kind of heat transfer equation is also given in this paper.

This work demonstrated the surface microfabrication of the UV-transparent fluoropolymer CYTOP (perfluoro 1-butenyl vinyl ether), by etching-assisted ablation using lasers with different pulse widths. In previous studies, we developed a technique for CYTOP microfluidic fabrication using laser ablation followed by etching and annealing. However, this technique was not suitable for some industrial applications due to the requirement for prolonged etching of the irradiated areas. The present work developed a faster etching-assisted ablation method in which the laser ablation of CYTOP took place in fluorinated etching solvent and investigated into the fabrication mechanism of ablated craters obtained from various pulse width lasers. The mechanism study revealed that the efficient CYTOP microfabrication can be achieved with a longer pulse width laser using this technique. Therefore, the rapid, high-quality surface microfabrication of CYTOP was demonstrated using a conventional nanosecond laser. Additionally, Microfluidic systems were produced on a CYTOP substrate via the new etching-assisted laser ablation process followed by annealing within 1 h, which is faster than the prior work of the microfluidic chip fabrication. Subsequently, CYTOP and polydimethylsiloxane substrates were bonded to create a 3D microfluidic chip that allowed for a clear microscopic image of the fluid boundary.
