UC San Diego Engineers Develop Microneedle Wearable Patch That Measures Glucose, Alcohol, Muscle Fatigue in Real Time

Wearable microneedle sensors that track multiple biomarkers in interstitial fluid are finding their way into chronic disease monitoring and sample collecting for clinical laboratory testing Wearable devices that replace finger sticks and blood draws for monitoring biomarkers of chronic diseases such as diabetes are the holy grail of non-invasive (or at least minimally invasive) technologies that collect specimens for clinical laboratory testing. Now, in their quest for alternatives to invasive...

Columbia University Researchers Say New High-Speed 3D Microscope Could Replace Traditional Biopsy, with Implications for Surgical Pathology

Columbia University’s MediSCAPE enables surgeons to examine tissue structures in vivo and a large-scale clinical trial is planned for later this year Scientists at Columbia University in New York City have developed a high-speed 3D microscope for diagnosis of cancers and other diseases that they say could eventually replace traditional biopsy and histology “with real-time imaging within the living body.” The technology is designed to enable in situ tissue analysis. Known as MediSCAPE, the...

UCSD Researchers Develop a Wearable Skin Patch That Monitors Blood Pressure, Glucose Levels, and Other Biomarkers in Human Sweat

Skin patch technologies could enable clinical laboratories to monitor patients’ vitals and report to medical professionals in real time Pathologists and clinical laboratory leaders have read many Dark Daily ebriefings on the development of skin patches over the years that do everything from monitoring fatigue in the military to being a complete lab-on-skin technology. Now, researchers at the University of California San Diego (UCSD) have developed a wearable patch that can monitor...

Researchers at Washington University in St. Louis Use Microneedle Patch with Fluorescent Nanolabels to Detect Biomarkers in Skin’s Interstitial Fluid

Painless technology could one day replace some phlebotomy blood draws as the go-to specimen-collection method for clinical laboratory testing and health monitoring Clinical laboratories have long sought a non-invasive way to do useful medical laboratory testing without the need for either a venipuncture or a needle stick. Now engineers at the McKelvey School of Engineering at Washington University in St. Louis in Missouri have developed a disposable microneedle patch that one day could be a...

Researchers at Emory University School of Medicine Develop Technology That Makes Urine Fluorescent When Transplanted Organs Are Rejected

This new technology could replace needle biopsies and allow physicians to detect rejection of transplanted organs earlier, saving patients’ lives Anatomic pathologists may be reading fewer biopsy reports for patients with organ transplants in the future. That’s thanks to a new technology that may be more sensitive to and capable of detecting organ rejection earlier than traditional needle biopsies. When clinicians can detect organ transplant rejection earlier, patients survive longer....
