Isolating and concentrating cells from whole blood: an interview with Victor Ugaz

There are several reasons for this. One is because analysis involving different kinds of blood cells may require you to be able to separate red blood cells from white blood cells, or plasma from whole blood etc.

UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Methodist Hospital develops new technology to rapidly detect drug-resistant TB

Technology developed by scientists at The Methodist Hospital Research Institute could halve the time it takes to diagnose tuberculosis infection, and also tell doctors in a day or two whether the bacteria are drug resistant -- a process that currently takes weeks. Initial tests of the device were recently described in Scientific Reports, a Nature online journal.

Special surface coating for stents to keep them in place

If a person's windpipe is constricted, an operation in which the surgeon inserts a stent to enlarge the trachea is often the only way to relieve their respiratory distress. But this grid-like implant can slip out of position, closing off the windpipe altogether. Researchers are working on a special surface coating for the stents to keep them in place.
