Microfluidic devices application

Dewetting (304-306) and phase separation phenomena are also amenable to in situ real-time SFM stndies. As shown by Jacobs and co-workers, the dewetting of PS on an oxidized silicon wafer can be followed in situ at elevated temperatures. These observations are nseful to develop a better imderstanding for film stability necessary in many modem applications of polymer ultrathin films in miniaturized electronic and microfluidic device applications.

The presented results show that the simple asymmetric pattern caused directional deformations and transport of a droplet. This technique is applicable to generation of a flow in microfluidic devices. 

There are more issues and complexity to be considered if various micro-electromechanical (MEMS)-type devices are included in the macroelectronics tool kit. As described previously, the materials and devices required for TFTs and circuits can provide adequate electromagnetic (visible and RF) sensitivity for many image-type applications. These materials may also provide satisfactory performance in pressure and strain sensors. Nanotube/nanowire-based devices look promising for various chem-bio sensors.85 However, there is little that is known about the ability to integrate printed microfluidic devices (and other such devices with moving parts) into a roll-to-roll-type process.

While it is true that microarray technology is gearing up for proteomics, it is perhaps still too early to predict what role microarrays will ultimately play. Proteins are much more complex molecules than nucleic acids and the suggestion has been made that additional tools and approaches will be needed. Microfluidic devices (electrophoresis, flow cytometry) with miniaturized detectors may also be applicable.

Zhu et al. [76] designed and fabricated microfluidic devices on polymethylmethacrylate (PMMA) substrates for electrochemical analysis applications using an improved UY-LIGA process. The microchannel structures were transferred from a nickel mold onto the plastic plates by the hot embossing... 

Some reviews [5-7] have appeared on NCE-electrospray ionization-mass spectrometry (NCE-ESI-MS) discussing various factors responsible for detection. Recently, Zamfir [8] reviewed sheathless interfacing in NCE-ESI-MS in which the authors discussed several issues related to sheathless interfaces. Feustel et al. [9] attempted to couple mass spectrometry with microfluidic devices in 1994. Other developments in mass spectroscopy have been made by different workers. McGruer and Karger [10] successfully interfaced a microchip with an electrospray mass spectrometer and achieved detection limits lower than 6x 10-8 mole for myoglobin. Ramsey and Ramsey [11] developed electrospray from small channels etched on glass planar substrates and tested its successful application in an ion trap mass spectrometer for tetrabutylammonium iodide as model compound. Desai et al. [12] reported an electrospray microdevice with an integrated particle filter on silicon nitride. 

The membrane technology has been tested in microfluidic devices. Normally a membrane is mounted between two chips, which make a microchannel, and fluid is allowed to pass through the membrane channel. Some papers are available on this method, which are discussed here. Hisamoto et al. [61] reviewed the application of capillary assembled microchips on PDMS as an online... 

Basically, microfluidic devices involve the flow of liquid in the nanoliter range, and, hence they are useful devices in separation science at nano or low level analyses of various ingredients in biological and environmental matrices. The most important applications of micro-fluidic devices include medical, chemical, and separation sciences.
