A new method of UV-patternable hydrophobization of micro- and nanofluidic networks
Lab on a Chip
This work reports a new method to hydrophobize glass-based micro-and nanofluidic networks. Conventional methods of hydrophobizing glass surfaces often create particulate debris causing clogging, especially in shallow nanochannels, or require skillful handling. Our novel method employs an oxygen plasma, silicone oil and ultraviolet (UV) light. The contact angle of the modified bare glass surface can reach 100° whilst the inner channels after treatment facilitate stable and durable water-inoildoi:10.1039/c1lc20716d pmid:22064947 fatcat:v6jznxmkjnbhvddifo2qx6iclu
