Gold Nanostars Help Design New Nanomedicines

Researchers from Northwestern University have developed a novel way to track how nanoparticles interact with cancer cells and whether they reach their tagets. The team’s work shows that if a nanoparticle targets cancer cells, it undergoes more rotational and translational movement compared to nanoparticles that cannot target cancer cells effe (Read more...)

OneDraw A1C Needle-Free Test System FDA Cleared

Drawbridge Health, out of Menlo Park, California, won FDA clearance for its OneDraw A1C Test System, which consists of the OneDraw Blood Collection Device and the OneDraw A1C Test. Designed for use by clinicians, the disposable product is used to draw, collect, and stabilize blood to measure hemoglobin A1c (HbA1c) levels to help manage glucose [&he (Read more...)

Stick-On Wearable Sweat Sensors to Monitor Exercise, Disease

The sweat excreted by our skin contains a number of metabolites and biomarkers that may be useful in managing disease, tracking athletic performance, and helping to identify health problems. Moreover, the amount of sweat that we produce can in itself be an important measure, but current sweat analysis techniques are very limited. Now, researchers a (Read more...)

Fully Flexible and Wireless Body Monitoring Sensors

Flexible body-worn sensors that conform to the skin have great potential for monitoring patient health, conducting long-term studies, and giving consumers a way to track their exercise and overall health. Although there have been flexible sticker-like body monitors developed in the past, they have all involved rigid electronic chips and batteries. (Read more...)

Accurate Blood Pressure Measured from Video Selfies

As many medical technologies continue to miniaturize, the task of accurately measuring blood pressure still requires a cumbersome upper-arm cuff. Scientists at the University of Toronto and Hangzhou Normal University in China have now shown that it may be possible to use existing smartphones to measure blood pressure. Their approach relies on notic (Read more...)

Wireless Brain Implant Controls Mice Using Drugs and Light

Optogenetics is a quickly evolving field that allows scientists to activate specific neurons using bursts of light. The technique may help to uncover the basis of neurological diseases and how to tame them. Using optogenetics to assess how different drugs affect the central nervous system may offer a powerful new scientific tool. To that end, [&hel (Read more...)

New Device Supports Dialysis Fistulas

Vascular Graft Solutions, a company based in Tel Aviv, Israel, has won the European CE Mark for its FRAME FR device for repair and support of high flow and aneurysmal arteriovenous fistulas. These are created in hemodialysis patients to allow for more blood to flow through a vein and give easy access for dialysis needles. […]

LipoGlo Makes Bad Cholesterol Glow Inside Zebrafish

So-called “bad cholesterol” is a molecular complex of fat and protein. Specifically, the protein is Apolipoprotein-B, or ApoB, and the fat is cholesterol. While ApoB helps fat molecules to move around the blood vasculature, it is also what makes cholesterol stick to vessel walls, forming dangerous plaques that are one of the main causes (Read more...)

Imperceptible Wearable Electronics Only Microns Thin

When we think of wearable electronics, devices such as smartwatches, chest-strap heart monitors, and wrist-worn activity trackers come to mind. In the future, and one that is seemingly not that far away, wearables may look like tattoos that are only microns thick. That may be thanks to researchers from the University of Houston, University of [&hel (Read more...)

Breath Analyzer for Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) is a condition in which fluid leaks into the lungs and builds up in the alveoli within. It is a rapidly progressive condition that often leads to terminal consequences, yet it can be difficult to diagnose and monitor. Now, researchers at University of Michigan have developed a portable device that [&hellip (Read more...)

Tiny Robots Aim to Work Inside Our Bodies

If we’re to have robots that work inside our bodies to find and cure diseases, they must be very small. To help make the dreams of futurists a reality, researchers at Georgia Tech have now created a robot that weighs only five milligrams and is no taller than the side of a US penny. The […]
