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...
Background
15.2.1. Micro Nanochannel Systems Because it is not feasible to transport fluids in nanochannels using an imposed pressure drop, electroosmosis and electrophoresis are often used. Application areas include rapid bio-molecular analysis these devices are called lab-on-a-chip. Small drug delivery devices may employ electrokinetic flow to control the rate of flow of drug to the patient. These devices may also be used as biomolecular separators because different ionic species travel at different...
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,...
