Laser Monitors Mitochondria to Predict Cardiac Arrest

Researchers have developed a laser device that can tell in real time whether tissues in the body are receiving enough oxygen. The laser system relies on resonance Raman spectroscopy, and could help doctors to predict cardiac arrest, as low oxygen levels in heart muscle is a warning sign that the heart could stop pumping. “With current [& (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...)

New Exhaled Breath Sensor to Spot Diseases, Monitor Health

At KAIST, the Korea Advanced Institute of Science and Technology in South Korea, researchers have developed a new breath sensor that uses protein-encapsulated nanocatalysts to spot certain biomarkers of diseases. While the breath can hold a lot of information about what’s going on inside the body, the variety of gasses present and the la (Read more...)

New Imaging Technique Provides Molecular Orientation in Samples to Help Study Neuro Diseases

A team of French scientists has developed a high speed imaging technique that provides them an unprecedented view of the chemical nature of biological samples. Not only does it provide an analysis of the chemical content, it also provides information about the orientation of the molecules detected. The newly available perspective of the molecular d (Read more...)

Sepsis-Detecting Point-of-Care Microfluidic Chip Developed

Sepsis is common and often deadly. Early detection of sepsis can be incredibly useful in preventing its full onset by allowing in-time administration of antibiotics. A couple of biomarkers of oncoming sepsis is leukocyte count and neutrophil 64 (CD64), a neutrophil surface antigen. Researchers at the University of Illinois have now reported in jour (Read more...)

Fluorescing Bandage Senses Wound’s Healing Process

Bandages used to treat chronic wounds present a host of challenges, particularly when they’re removed to examine and clean a wound. While this is necessary, the process can be very painful for the patient, difficult on the clinician, and the wound may become infected due to being exposed. A team of researchers from Swiss Federal Laborato (Read more...)

Videssa Breast Blood Diagnostic Test for Breast Cancer

Provista Diagnostics, a company based in New York City, has developed the Videssa Breast blood-based proteomic test to detect breast cancer. At present, after an abnormal mammogram doctors are faced with a difficult decision: whether to carry out an invasive biopsy or not. “When a mammogram yields an abnormal result, the challenge for ev (Read more...)
