Webchloroform and purple for PMMA. Fig. S1A shows the full spectrum of the standard solution. The standard sample was made by dissolving 53.7 mg of PMMA and 13.2 mg of chloroform in deuterated acetone. Peaks (a), (b), and (c) were identified with the methyl ester, methylene, and methyl groups of PMMA, respectively. WebPMMA devices effectively bonded within 30 s at a low pressure using clamps, and a clogging-free microchannel was achieved with the optimized 50% acetic acid. For surface characterizations, contact angle measurements and bonding performance analyses were conducted using predetermined acetic acid concentrations to optimize bonding conditions.
