Microrobots Take Minutes to Detect C. diff in Stool Samples

Detecting bacterial infestations within the GI system, particularly using low cost methods, takes so much time that treatment is often administered too late. Clostridium difficile (C. diff) is a particular nasty nuisance that kills many frail patients, and even with a hospital lab it can take up to two days to get the results. Researchers (Read more...)

Graphene Biosensors to Detect Lung Cancer

Exhaled breath is rich in biomarkers that can point to the presence of disease. In particular, ethanol, acetone, and isopropanol can point to the presence of lung cancer, so having a way of measuring these chemicals in breath might provide a way to diagnose lung cancers or to screen for them. Current methods of measuring […]

Electronic Nanomesh Gently Hugs Beating Heart Cells

Unlike with most other cells, studying the heart’s beating cardiomyocytes is prone to difficulty because attaching rigid sensors to moving cells hinders the movement of those cells. A collaboration of Japanese scientists at University of Tokyo, Tokyo Women’s Medical University, and RIKEN research institute have developed (Read more...)

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...)
