New heart attack detector can produce results in a couple minutes
American researchers from Johns Hopkins University have developed an innovative chip. It can detect heart attack biomarkers in the blood in just a few minutes.
Standard blood tests such as creatine kinase and troponin tests often require long waits for results. The new chip uses a unique “metasurface” consisting of polystyrene beads and alternating layers of gold and silicon. This combination amplifies electric and magnetic fields, allowing blood to be analyzed quickly and accurately, even at low biomarker concentrations.
According to the authors of the development, this technology has the potential for adaptation in the diagnosis of cancer and infectious diseases.

New blood-testing device can produce results from 1 drop in an hour
Scientists at the University of Colorado at Boulder have unveiled an innovative technology that could replace traditional blood tests from a vein. The new palm-sized diagnostic device requires just 1 drop of blood and can provide results in 60 minutes.
At the heart of the technology are tiny particles with special coatings that recognize and capture targeted biomarkers in the blood. These particl
