Acoustofluidics Pulls Exosomes from Whole Blood

Exosomes are tiny vesicles that are released by the body’s myriad of cells and that are found in blood, urine, and other bodily fluids. Their role within our bodies is still largely a mystery, but there’s already considerable evidence that they may be biomarkers of disease and indicators that certain processes are happening within the [ (Read more...)

$40 Keychain Device Detects Food Allergens

For those with allergic reactions to certain foods, cross-contamination or accidental mislabeling can lead to reactions ranging from annoying to life-threatening. To address this health need, researchers at Harvard Medical School have made a device that can quickly, inexpensively, and accurately detect common food antigens. The integrated exogenous (Read more...)

Paper Test for Zika Powered by Gold Nanoparticles

Zika is often a silent disease that might not display any symptoms in infected persons, making screening particularly important. In the developing world, mobile testing systems that can be easily transported and used are not available, so sending a sample to a lab is still required to detect Zika infected individuals. Researchers at Washington Univ (Read more...)

Smartphone-Powered Diagnostic Spectrum Analyzer Shrinks a Hospital Lab Into Portable Device

Bioengineers at the University of Illinois at Urbana-Champaign have turned a smartphone into a portable diagnostic laboratory capable of performing a range of spectrum analyses that is currently done using large and expensive stationary machines. The investigators built a smartphone attachment that utilizes the smartphone’s camera to analyze (Read more...)

Expansion Microscopy Swells Samples for Better Imaging

When trying to use light and conventional optics to image a biological sample at great detail, one eventually encounters the fact that objects smaller than the light’s wavelength cannot be resolved. While technological tricks have been developed to overcome this limitation in some ways, a team of researchers from MIT and Harvard have ins (Read more...)
