  1. Optical Imaging Through Opaque Layers

    If you were to shine a light on someone’s skin, you wouldn’t expect to see what’s going on behind it. With a new technique published in The Optical Society’s journal Optica, however, you can do just that with surprisingly high levels of resolution.

  2. Manufacturing A More Accurate Bioimaging Protein

    Using certain cells lines, scientists at the Helmholtz Zentrum München research center in Germany have found a way to manufacture the bioimaging protein Amrose. The novel approach provided the cells with the right materials and then let them formulate into the complex molecule independently.

  3. New Autofluorescence Device Tracks Wound Infections

    The clinical evaluation of chronic wounds has long suffered from subjective bias. A new device, however, may make invisible bacteria detectable without lab tests or other interventions.

  4. Multi-Tasking Nanoparticle Combines Imaging And Therapeutics

    Using nanoparticles for diagnosis is a hot area of research, as is the use of nanoparticles for therapeutic delivery. Combining the two functions together in a single nanoparticle, however, is a new step forward from UC Davis researchers. 

  5. Laser-Based Diabetes Testing, No Blood Required

    Every day, millions of diabetics measure their blood glucose levels by pricking themselves to get a blood sample, but thanks to a new advance from Princeton researchers, this may not be necessary for much longer.

  6. New Photoacoustic Device Provides Non-Invasive, Deep-Tissue Imaging

    Until now, there has been no suitable method to measure the depths of tumors and create maps of how extensive those tumors are. Researchers from Washington University in St. Louis, however, have developed a new device that uses photoacoustics in order to address that problem.

  7. Earbuds For Medical Monitoring — Unconventional Design Yields Unique Benefits

    Wearable biometric sensors for measuring vital signs are becoming increasingly prevalent for exercise and health monitoring. These technologies commonly take shape as bracelets or designs that pass around the chest.

  8. Will Spectroscopic Exams Replace Biopsies?

    Researchers at the University of Texas at Austin (UT Austin) may have found a way to improve the early detection of skin cancers and reduce the number of unnecessary biopsies with a new, 3-in-1 optical cancer probe.
