Using an ultrasonic vibration microfluidic chip to generate UV-crosslinking microparticles

This study managed to generate UV-photopolymerized microparticles using an ultrasonic vibration microfluidic chip coupled with external UV-crosslinking reaction. We have demonstrated that the sizes of UV-crosslinking microparticles were able to be controlled from 9.46 to 1.18 mum in diameter (with a variation of less than 10%) by altering the ultrasonic vibration distance and the voltage of power supply provided to transducer. The proposed ultrasonic vibration microfluidic chip was easy to fabricate and capable of high throughput and low cost.
