MICROFLUIDIC SYSTEMS USING SURFACE ACOUSTIC ENERGY AND METHOD OF USE THEREOF

摘要

A microfluidic system including a piezoelectric substrate (1), a wave generation means (5) for generating a wave in the piezoelectric substrate, and a rigid secondary substrate (11) coupled to said piezoelectric substrate (1) and providing a working surface (12) for the system, the secondary substrate (11) being formed of a relatively chemically inert material, and the coupling of the piezoelectric substrate (1) with the secondary substrate (12) being provided by a fluid coupling layer (13) located between the piezoelectric substrate (1) and the secondary substrate (12) overlaying the piezoelectric substrate (1). In one application, the system may be used to synthesize zeolite nanocrystals via atomization of a liquid droplet (15).
