A simple microfluidic chip fabrication technology for UV curing molding

A light cured resin,monotner,and photoinitiator agent have been employed as a replacement for traditional polymer materials such as glass and silicon to provide a low-cost,fast process for the fabrication of microfluidic chips,giving a light curing molding method rather than the traditional chip processing method.A bonding method suitable for light curing material chips has been developed at the same time.Tests showed that the reproducibility,consistency and patency of the obtained runner are good.The results also show that the chip has good transmittance,with the infrared and ultraviolet transmissivity being 94％ and 24％ respectively,and droplets of oil in water are formed in the mixed channel of the chip.Since the method has low materials requirements and the manufacturing cost,it can meet the needs of mass production.
