We report on the fabrication and characterization of a low-cost micro-Coulter counter fabricated from biocompatible materials (Poly-dimethylsiloxane, glass and gold) and incorporating hydrodynamic focusing. The developed micro-Coulter counter offers a low-cost alternative to equivalent existing devices and, thanks to the hydrodynamic focusing, provides high versatility, being able to probe part...

The size of every component for opto-electrical devices or micro electro-mechanical systems (MEMS) has been reduced in recent years due to progress in opto-digital communications technology. The demands for micro-sized holes, slits and 3D structures of hard brittle materials such as ceramics and glass are considerable, and this has stimulated research into new methods and systems for a micro-me...

The greatest challenge being faced for realization of Micro-Electro Mechanical System (MEMS) technology is the lack of a simple, quick and reliable method for the fabrication of 3-D microchannel in the range of micrometers. A novel fabrication technique which opens possibilities for the production of these microfluidic channels is presented in this paper. The present paper highlights the possib...

In present novel work, we have synthesized a novel quaternary Se76Te20Sn2Cd2 glass in bulk form. Four laser light sources from UV-Vis-IR region have been used to investigate the laser-induced effects on the micro-hardness to check the candidature of this material for possible application in fiber optics. The micro-hardness of the quaternary Se76Te20Sn2Cd2 glass is increased appreciably after la...

We present a laterally emitting, coupled cavity micro fluidic dye ring laser, suitable for integration into lab-on-a-chip micro systems. The micro-fluidic laser has been successfully designed, fabricated, characterized and modelled. The resonator is formed by a micro-fluidic channel bounded by two isosceles triangle mirrors. The micro-fluidic laser structure is defined using photo lithography i...

Recently, the magnetorheological (MR) polishing process has been examined asa new ultra-precision polishing technology for micro parts in MEMS applications. In theMR polishing process, the magnetic force plays a dominant role. This method uses MRfluids which contains micro abrasives as a polishing media. The objective of the presentresearch is to shed light onto the material removal mechanism u...

This paper presents a new wafer-level micromold processing technology of Pyrex7740 glass for micro-fluidic devices, which is based on viscous deformation at temperatures above glass softening point temperature, and it is also described as a thermoforming process. The fabrication of microchannels on Pyrex7740glass wafer with high aspect ratio has come true. It could also retain the original surf...

We have designed a non-membrane micro surface tension alveolus (MISTA) in a glass microchip for direct gas exchange and micro gradient control. Hemoglobin (Hb) in the liquid phase indicates the rapid gas gradient changes of O2 and CO2 shifted by the difference in pressure between the liquid and the gas.
