We study the flow within a stationary drop in a Hele-Shaw cell. The experiments are performed in a microfluidic channel, whose surface is patterned with a single hole that serves to anchor the drop while the outer fluid continues to flow. The recirculation ...
We present a novel optofluidic differential method for carrying out absorbance spectroscopy of subnanolitre volumes of liquid samples on a microfluidic chip. Due to the reduction of liquid volume, the absorbance detection in microfluidics is often hindered ...
We present a novel image-based method to measure the on-chip microfluidic pressure and flow rate simultaneously by using the integrated optofluidic membrane interferometers (OMIs). The device was constructed with two layers of structured polydimethylsiloxa ...
The physiological properties of cells are typically investigated in ensembles yielding averaged data that mask heterogeneities present in any cell population. Single-cell analysis techniques based on microfluidic "lab on a chip" (LOC) devices have recently ...
Nematogens rotate by the application of external fields, thereby enabling optical modulation. This principle has had a profound impact on our daily lives through the plethora of liquid-crystal displays in use around us(1,2). However, the wider use of nemat ...
We present a microfluidic device capable of separating platelets from other blood cells in continuous flow using dielectrophoresis field-flow-fractionation. The use of hydrodynamic focusing in combination with the application of a dielectrophoretic force a ...
Microfluidics plays a key role in the design of automated platforms for realizing biological assays in a miniaturized format. Several advantages are offered by a microfluidic system, namely, low sample and reagent consumption (typically a few microliters), ...
This paper reports on a new microfluidic device for temperature stimulation of cell in in-vitro culture. Micro- electrodes in a meander shape are embedded into the microfluidic channels to generate either a temperature gradient through the culture chamber ...
We present a novel nonenzymatic carbon nanotube sensor integrated in a microfluidic channel for the detection of sugars. The sensor is assembled as a liquid-gated field-effect transistor, with the transistor channel composed of 1 to 10 nanotubes, which are ...
