On-demand Control of Microfluidic Flow via Solenoid Microvalve Suction
نویسندگان
چکیده
A simple, low-cost and on-demand microfluidic controlling platform was developed based on a capillary-tuned solenoid microvalve suction effect without any outer pressure source. The suction effect was employed as a stable driving force for manipulating micro-fluid by connecting a piece of capillary tubing between the microvalve and the chip. The suction volume could be controlled from microliters to picoliters level by decreasing the energized duration or increasing the capillary length. Several microfluidic applications such as cell/droplet sorting and on-demand size-controllable droplet generation was demonstrated on the platform and both simulations and experiments confirmed this platform with good controllability and stability.

متن کاملMicrovalves based on ionic polymer-metal composites for microfluidic application.
Simple and highly efficient microvalve systems based on an ionic polymer-metal composite (IPMC) diaphragm actuator have been developed. The microvalve system that was fabricated in this work operates when open and close voltage is applied, due to the phenomena of lithium ion flux and the subsequent electro-osmotic drag of water to the cathode. IPMC was prepared by compositing with platinum nano...

An integrated microvalve fabricated in a stiff polymeric (polycarbonate) device allows for formation of droplets and bubbles of arbitrary volumes and at arbitrary times of emission. Predesigned protocols of formation of sequences of volumes, intervals between the droplets and their chemical compositions can be practically and reproducibly realised and controlled from a personal computer. The de...
متن کاملControl of pressure-driven components in integrated microfluidic devices using an on-chip electrostatic microvalve
Pressure-driven actuators play a critical role in many microfluidic technologies, but the ancillary equipment needed to operate pneumatic and hydraulic platforms has limited their portability. To address this issue, we created an electrostatic microvalve used to regulate pressures in hydraulic control lines. In turn, these control lines are able to actuate pressure-driven components, e.g., micr...
