Microvalves and Micropumps for BioMEMS
This review presents an extensive overview of a large number of microvalve and micropump designs with great variability in performance and operation. The performance of a given design varies greatly depending on the particular assembly procedure and there is no standardized performance test against which all microvalves and micropumps can be compared. We present the designs with a historical pe...
متن کامل3d-printed Microvalves and Micropumps
This paper describes a novel microvalve design that can be fabricated using stereolithography without need for the manual alignment and bonding steps required of PDMS microvalves. Multiple units of these microvalves can be arranged together and operated in tandem to perform fluid routing, switching, and pumping tasks. We demonstrate the performance of a four-valve fluid switch connected to a do...
متن کاملMicropumps, microvalves, and micromixers within PCR microfluidic chips: Advances and trends.
This review surveys the advances of microvalves, micropumps, and micromixers within PCR microfluidic chips over the past ten years. First, the types of microvalves in PCR chips are discussed, including active and passive microvalves. The active microvalves are subdivided into mechanical (thermopneumatic and shape memory alloy), non-mechanical (hydrogel, sol-gel, paraffin, and ice), and external...
متن کاملA review of microvalves
This review gives a brief overview of microvalves, and focuses on the actuation mechanisms and their applications. One of the stumbling blocks for successful miniaturization and commercialization of fully integrated microfluidic systems was the development of reliable microvalves. Applications of the microvalves include flow regulation, on/off switching and sealing of liquids, gases or vacuums....
متن کاملCatalytically induced electrokinetics for motors and micropumps.
We have explored the role of electrokinetics in the spontaneous motion of platinum-gold nanorods suspended in hydrogen peroxide (H2O2) solutions that may arise from the bimetallic electrochemical decomposition of H2O2. The electrochemical decomposition pathway was confirmed by measuring the steady-state short-circuit current between platinum and gold interdigitated microelectrodes (IMEs) in the...
