Quantitating Trap Characteristics

In order to assess whether a quantitative design is successful, one needs some quantitative validation of the fields and forces in DEP traps. Given that the complete DEP theory is known and that the properties of at least some particles are known, it should be possible to quantitate trap parameters. Those that are of interest include trap strength, field strength, and the spatial extents of the trap. Measuring traps requires a quantitative readout. This typically takes the form of a test...

Diagnostic Techniqes In Microfluidics

The majority of diagnostic techniques in fluid mechanics were originally developed for turbulent flows, where flow parameters such as velocity and pressure have strong stochastic fluctuations. Classical'flow measurement diagnostic techniques such as hot-wire anemom-etry and laser-Doppler velocimetry LDV therefore emphasized measurements at a single spatial location with high temporal resolution or sampling rate. Over the last twenty years, advances in lasers and imaging technology have led to...

Applications Of Intelligent Polymer Networks As Recognition Elements

A number of research groups have utilized hydrogels as functional components in biomedical applications, such as in biomaterials and biosensors. Ito and collaborators 3840 have patterned pH-sensitive and thermo-sensitive hydrogels and proposed these microstructures for use in various microdevices. In numerous studies done by Matsuda and coworkers 41-45 , hydrogels have been micropatterned using a surface polymerization technique induced by an iniferter acts as an initiator, a transfer agent,...
