Modification research on in wall of capillary copper tube with Norland optical adhesive 68 in a double stereo PCR microfluidic chip

J. Wu, Wang, F. J., Wang, C. Y., Yu, K. X., Ma, Y., Chen, T., Li, Y. H., and Zheng, Y., Modification research on in wall of capillary copper tube with Norland optical adhesive 68 in a double stereo PCR microfluidic chip, vol. 14, pp. 13603-13611, 2015.

In this study, a Norland optical adhesive 68 (NOA68) film, approximately 2.2 μm thick, was manufactured using ultraviolet solidified NOA68 in apparatus manufacturing film on the inwall of a capillary copper pipe, developed in our laboratory. The roughness of the inwall of capillary copper pipe was improved from Ra = 0.766 to 0.204 μm and the contact angle was improved from approximately 96° to 55°, increasing hydrophilicity.
