Microfluidics Based Phantoms of Superficial Vascular Network
News Jul 11, 2012
Several new bio-photonic techniques aim to measure flow in the human vasculature non-destructively. Some of these tools, such as laser speckle imaging or Doppler optical coherence tomography, are now reaching the clinical stage. Therefore appropriate calibration and validation techniques dedicated to these particular measurements are therefore of paramount importance. In this paper we introduce a fast prototyping technique based on laser micromachining for the fabrication of dynamic flow phantoms. Micro-channels smaller than 20 µm in width can be formed in a variety of materials such as epoxies, plastics, and household tape. Vasculature geometries can be easily and quickly modified to accommodate a particular experimental scenario.

Microanalysis of Biological Samples for Early Disease DetectionNews
A group of researchers from Osaka University has now developed a nonlinear optical crystal (NLOC) chip, which combines THz waves with a microfluidic device, utilizing the close proximity of the THz wave source and the solution of interest in a microchannel.READ MORE
Novel Green Chemistry Method Improves Pharmaceutical Manufacturing EfficiencyNews
About 70 percent of pharmaceuticals are manufactured using palladium-driven catalytic processes that are either fast or efficient - but not both. Researchers have now developed a green chemistry method that combines aspects of both processes to improve efficiency at a minimal cost of processing time.READ MORE
Radioprotective Drugs Assessed Using Human Gut Organ-on-a-ChipNews
Researchers have published a study using an organ-on-a-chip (Organ Chip) model of the human gut that reveals the intestinal blood vessel cells may play an important part in radiation-induced intestinal injury, and it confirms that a potential radioprotective drug, dimethyloxaloylglycine (DMOG), suppresses the intestine’s responses to radiation injury.READ MORE
