No more needles for diagnostic tests? Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells — ScienceDaily

Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen […]

This laboratory apparatus is most commonly used… view more  Credit: Florida Atlantic University To properly monitor and help curb the spread of COVID-19, several millions of diagnostic tests are required daily in […]

Creating better diagnostic tools with light scattering nanoparticles

Recent advanced in nanoparticle-based SERS imaging has led to better diagnoses of diseases like cancer, and improvements in image-guided tumor surgeries. Since the discovery of the X-ray more than a century ago, the rapid development of radiological diagnosis welcomed a new era for medical imaging. Through innovative new technologies, not only have we enabled improved […]
