Innovative platform improves diagnostics and detection of biomolecules

Separating target molecules in biological samples is a critical part of diagnosing and detecting diseases. Usually the target and probe molecules are mixed and then separated in batch processes that require multiple pipetting, tube washing and extraction steps that can affect accuracy.

LINX device may help relieve chronic heartburn symptoms

Clinical trial results published in the New England Journal of Medicine this week offer additional evidence that a new device may help relieve chronic heartburn symptoms that standard treatment cannot. The Keck Medical Center of USC was one of 14 U.S. and European medical centers to test the device prior to its March 2012 approval by the U.S. Food and Drug Administration.

TSRI chemists develop new cell-marking method

Chemists at The Scripps Research Institute (TSRI) have found an easier way to perform one of the most fundamental tasks in molecular biology. Their new method allows scientists to add a marker to certain cells, so that these cells may be easily located and/or selected out from a larger cell population.

New technique can manipulate and measure magnetic particles without contact

If you throw a ball underwater, you'll find that the smaller it is, the faster it moves: A larger cross-section greatly increases the water's resistance. Now, a team of MIT researchers has figured out a way to use this basic principle, on a microscopic scale, to carry out biomedical tests that could eventually lead to fast, compact and versatile medical-testing devices.

Biomedical engineers develop SMART detector for flu diagnosis

In April 2009, the world took notice as reports surfaced of a virus in Mexico that had mutated from pigs and was being passed from human to human. The H1N1 "swine flu," as the virus was named, circulated worldwide, killing more than 18,000 people, according to the World Health Organization. The Centers for Disease Control and Prevention in the United States said it was the first global pandemic in more than four decades.

Vanderbilt to develop low-cost extraction device for people in resource-poor settings

They call it "The Extractionator." The prototype looks like nothing more than a length of clear plastic tubing until you inspect it closely. But it could be the basis of an easy-to-use and low-cost sample collection and preparation system that will help bring the benefits of medical diagnostic testing to the people who live in the poorest areas of the world.
