Measurement of kon without a rapid-mixing device

Microfluidic baker's transformation device for three-dimensional rapid mixing.

We developed a new passive-type micromixer based on the baker's transformation and realized a fast mixing of a protein solution, which has lower diffusion constant. The baker's transformation is an ideal mixing method, but there is no report on the microfluidic baker's transformation (MBT), since it is required to fabricate the complicated three-dimensional (3D) structure to realize the MBT dev...

Rapid Mixing

In the past decade many proofs of tractability have involved showing that some Markov chain ”mixes rapidly”. We will do a fast tour of the highlights of Markov chain mixing, with a view toward answering—or at least addressing—the following questions: What is rapid mixing? How do you prove it, and why would you want to? Does it really have anything to do with computational complexity? And, most ...

DEVELOPMENT OF A RAPID AND SENSITIVE RADIOIMMUNOASSAY FOR MEASUREMENT OF AFLATOXIN B 1 IN BIOLOGICAL SAMPLES

Aflatoxin B I (AFB) isa well known hepatocarcinogen in several animal species and probably a causative agent in human hepatocellular carcinoma. Humans are exposed to AFB by ingesting contaminated food. Aflatoxin contamination encountered in human foods is usually at low levels which is difficult to measure by chromatographic methods. Therefore in the present study we have developed an immun...

Mixing enhancement in a microfluidic device

A microprocessor-controlled gas mixing device.

This paper describes the use of solenoid valves for the production of binary gas mixtures. The system is controlled by a microprocessor and is capable of delivering accurate flows and concentrations of gases over the ranges commonly used in anaesthesia. Since the flow produced by the valves is pulsatile, a system for mixing the gases and smoothing the pulses is described. A back pressure regula...
