Stick-On Solar-Powered Heart Monitor Fits on a Finger

Scientists at the Riken, a major Japanese research institute, and University of Tokyo have developed a remarkable ambient light-powered cardiac monitor that looks like a transparent bandage. The underlying technology makes possible other flexible body-worn sensors that don’t need to have an external electric source powering them, including te (Read more...)

Nanoparticle Swarms to Deliver Medical Therapies Across Body

Scientists at the Chinese University of Hong Kong have developed a way to get nanoparticles to group and move as swarms, similar to how hundreds of bees and birds can fly together. The technology may have implications for medicine, helping to guide nanoparticles toward certain organs or sites of cancer. The research team’s nanoparticles are [ (Read more...)

Drug Ferrying Nanoparticles for Treating Kidney Diseases

Drugs targeting the kidneys are naturally difficult to develop because kidneys filter things out and send them out for disposal (filtration, reabsorption, secretion, and excretion). Moreover, the liver also helps keep foreign objects out of the body. Now researchers at the University of California have created nanoparticles that are desig (Read more...)

Nanoparticles Packed with Iron as Powerful MRI Agents

While improving MRI machines is one way of making the clinical images look better, another is improving the injectable contrast agents that are compatible with magnetic resonance. Gadolinium-based MRI contrast agents are the most commonly used now, but they carry safety concerns and they don’t have alternatives for some tests. Rice University (Read more...)

Nanobots Eat Up Nerve Agents and Release Life Saving Antidote

Chemists at Pennsylvania State University have been doing some remarkable work to create self-propelled nanobots, and lately the investigators have focused their attention on using nanobots to stop nerve agent attacks. The nanobots intake chemical compounds, react with them, and push the product of the reaction out of one end. This makes the nanobo (Read more...)

Mechanoceuticals to Replace Chemical Drugs by Tugging on Cells

Chemicals, delivered in the form of drugs, are the most common way of influencing the activities of cells in our bodies. While great in many ways, there are a myriad of limitations and side effects for clinicians and patients to grapple with. UCLA bioengineers are investigating whether targeted physical manipulation could serve as an additional [&h (Read more...)

Technique to Make Nanoparticles Work Inside Pills

Nanomedicine requires the nanoparticles that are administered to be properly absorbed by the body. Given orally via a pill, nanoparticles mostly end up being metabolized and/or excreted by the gastrointestinal system. Researchers at the University of Utah have now come up with a way of making nanoparticles much easier to uptake by the body through (Read more...)

Nano-Optic Endoscope Allows High-Resolution Imaging

Researchers at Harvard University and Massachusetts General Hospital have developed a new type of endoscopic imaging catheter. The catheter uses metalenses, which contain nanostructures to focus light, to achieve higher resolution imaging than conventional catheter imaging systems. So far, the researchers have used the new system to image deep into (Read more...)

Microfluidic Device Detects Bacteria in Tiny Samples

Canadian researchers at McGill University and University of Toronto have come up with a new device for rapid detection of small concentrations of pathogenic bacteria within tiny samples. The technology may help to spot diseases early, and so allow clinicians to better treat their patients while slowing down the spread of infection. The device consi (Read more...)
