Microfluidic chip driven by acoustically excited droplet-shaped microbubbles and its fabrication process
This invention relates to a microfluidic chip driven by acoustically excited droplet-shaped microbubbles and its fabrication process. A droplet-shaped microbubble array is obtained through microfluidic chip structure design. Under acoustic excitation, the microbubbles oscillate, generating asymmetric acoustic-flow vortices, which in turn directionally drive the microfluidic fluid within the microchannels. The flow rate can be linearly controlled by adjusting the driving voltage, offering advantages such as non-contact, pollution-free, and highly efficient directional driving. The fabrication process is based on MEMS technology, employing nitrogen plasma bonding and soft lithography, resulting in low cost and suitability for mass production. This invention solves the problem of the lack of directionality in traditional symmetrical acoustic-flow vortices and can be widely applied in fields such as biomedicine, drug delivery, and chemical analysis.
