Microfluidic manipulation via Marangoni forces
A convective flow system is engendered when two liquid droplets, or a liquid droplet and a solid surface, are maintained at different temperatures. Such flows give rise to Marangoni forces which under proper conditions prevent droplet coalescence, cause fluid motion, and dewetting. We present a study of adsorbed and applied fluid movement on a solid surface driven by surface tension gradients c...

متن کاملProgrammable v-type valve for cell and particle manipulation in microfluidic devices.
A new microfluidic valve or a "v-type valve" which can be flexibly actuated to focus a fluid flow and block a specific area of a microchannel is demonstrated. Valves with different design parameters were fabricated by multilayer soft lithography and characterized at various operating pressures. To evaluate the functionality of the valve, single microparticles (∅ 7 μm and ∅ 15 μm) and single cel...
متن کاملOptical manipulation and detection of biological cells in bio-microfluidic devices
Focused laser beams can be used to trap and manipulate small particles and biological cells without mechanical contact. Particles trapped by such a laser beam can be used as local force probes in biomicrofluidic environment. Optical manipulation and separation of biological cell is a flexible technology with important potential biomedical applications, like cancer cell detection. Optical forces...
متن کاملPiezoelectric Actuators for In-Liquid Particle Manipulation in Microfluidic Applications
The possibility to generate acoustic modes based on FPWs (Flexural Plate Waves) in a generic non-piezoelectric substrate for microfludic applications by means of piezoelectric actuators has been explored and described in this paper. The FPW acoustic modes are generated by means of actuators made of Lead Zirconate Titanate (PZT) layers with InterDigital Transducers (IDTs) screen-printed on alumi...
