Spray Gel Helps Prevent Cancer Spread Following Surgery

All too often after tumor resections cancers end up spreading to other parts of the body. Metastasis is not well understood, but researchers at University of California, Los Angeles, University of North Carolina, Chapel Hill, South China University of Technology, Guangzhou and Fudan University in China, have developed and tested a re (Read more...)

Nanoneedle Skin Patch to Inject Drugs Into Cells

Delivering drugs directly into skin cells using microscopic nanoneedles may allow for highly effective treatment of skin conditions without injuring the cells that are treated. Silicon nanoneedles have been developed in the past that can do such a trick, but they’re stiff and can be painful, in addition to quickly losing their effectiveness. (Read more...)

DNA Origami Nanoparticles to Treat Acute Kidney Injury

DNA origami is a technique for building different shaped molecules out of the four standard nucleotide bases. Various forms can be constructed, such as tubes, pyramids, and cubes, and the shapes of these molecules can significantly affect their functionality. Now they’ve been shown to be useful for treating acute kidney injury (AKI). The  (Read more...)

Electronic Synthetic Cells Small Enough for Injections

If injectable autonomous robots are to be used in medicine, they must be tiny and capable of being manufactured by the million. They must also have some kind of electronics inside for diagnostic or therapeutic capabilities. Researches at MIT have developed a method for producing so-called “syncells,” or synthetic cells, that can process (Read more...)

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...)
