摘要

We present a cleanroom-compatible fabrication route to open space microfluidic devices, utilizing a multilayer lamination/photolithography process on the wafer scale. The devices were applied to generate and maintain molecular surfactant films. In a dedicated setup, film stability was investigated in conjunction with 108 kHz ultrasonic sound, and response to acoustic waves in the audible range was determined.
