The active control system, based on the use of micro pneumatic actuators, was designed to control the deployment and retraction of the tab along the oscillating cycle.
Experimental data show that for disease diagnosis, the bio-sensing chips integrated with the micro-pneumatic valves and the peristaltic micro-pumps could successfully perform diagnosis tests.
Small amounts of samples and reagents could be injected into the diagnosis chips using the micro-pumps and the micro-pneumatic valves could effectively control the movement of the samples and reagents.
The present study reports a microfluidic system using the concept of membrane-movement to design and fabricate micro-pneumatic valves and pumps to form a bio-sensing diagnostic chip.
A new torch, a shortened version of a standard demountable torch, is proposed for facilitating direct injection of liquid samples into an inductively coupled plasma mass spectrometer using conventional and micro-pneumatic nebulizers.
Results presented in this work prove the performance of the DLP printer we build up and show the convenience of fabricating micro soft pneumatic actuators integrally using DLP 3D printing approach with fast speed and high precision.
145, 146 Most recently, one patient with treatment-resistant onychomycosis was successfully pretreated with a micro motor pneumatic diamond drill device and subsequent ALA-PDT with red light.
In this work, a poly(dimethylsiloxane) (PDMS) microchip-based immuno-sensing platform with integrated pneumatic micro valves is described.
Down to the present day, a thermo-pneumatic micro-membrane pump [A. Wego, L. Pagel, A self-filling micro-pump based on PCB technology, Sensors Actuat. A 88 (2001) 220 226.], diverse micro-mixers [H.
Instead of using traditional pneumatic micro-pumps, the current study adopts a new design called "spider-web" micro-pumps to increase the pumping rate, and more importantly, improve the uniformity of flow rates inside multiple micro-channels.
