Observation and manipulation of a single DNA molecule in real time have been applied for gene analyses and novel biochemical analyses of DNA-protein interactions. The DNA molecule in solution frequently changes its position and its shape due to Brownian motion, therefore precise handling technique is required. At the same time, miniaturized chemical reaction systems such as micro total analysis systems...
We report on a droplet-based, in situ formed tunable cylindrical microlens array in microchannels. The deionized water microlenses are formed via liquid-air interfaces of liquid droplets at T-shaped junctions of octadecyltrichlorosilane (OTS) treated polymerized isobornyl acrylate [poly(IBA)] microchannels, and their focal length can be tuned individually by pneumatic manipulation. These microlenses...
Oxygen is an important parameter with significant effect on cellular development and function. Based on microfluidics, laminar flow and hydrodynamic focusing provide ideal tools for the generation of controlled micro-environments and their application as stimuli to cells. In this paper we demonstrate, for the first time inside a microfluidic device, the generation and characterization of hydrodynamically...
In an effort to manufacture a high-performance disposable microfluidic system for applications in medical diagnostics, a series of studies were carried. Surface modification on COC, nanoparticle-based immunoassays on COC, manufacturing cross flow microfluidic system, synthesis of a pair of molecules for fluorescence resonance energy transfer (FRET) and preparation of a FRET nanoparticle are presented...
A concept and a device for automatic handling of solutions using an electrochemical cell integrated in a microflow channel are proposed. An electrowetting-based valve was formed in a flow channel of poly(dimethylsiloxane) (PDMS) to separate two solutions in a mixing area. Another flow channel with a cell was formed to transport an electrolyte solution and activate the cell. Since the cell was electrically...
