Novel anti-cancer nanomedicine for efficient chemotherapy

Researchers at the University of Helsinki in collaboration with researchers from Åbo Akademi University,Finland and Huazhong University of Science and Technology,China have developed a new anti-cancer nanomedicine for targeted cancer chemotherapy. This new nano-tool provides a new approach to use cell-based nanomedicines for effcient cancer chemotherapy. Exosomes contain various molecular constituents of their cell of origin, including proteins and RNA. […]

Sheaths drive powerful new artificial muscles

Over the last 15 years, researchers at The University of Texas at Dallas and their international colleagues have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon nanotubes (CNTs) to ordinary fishing line. In a new study published July 12 in the journal Science, the researchers describe their latest advance, called sheath-run artificial muscles, or […]

Synthetic joint lubricant holds promise for osteoarthritis

A new type of treatment for osteoarthritis, currently in canine clinical trials, shows promise for eventual use in humans. The treatment, developed by Cornell University biomedical engineers, is a synthetic version of a naturally occurring joint lubricant that binds to the surface of cartilage in joints and acts as a cushion during high-impact activities, such as running. “When the production […]

New 3D microscope visualizes fast biological processes better than ever

“Many important biological processes occur in three dimensions and on millisecond timescales,” says Lars Hufnagel on the rationale for developing the new microscope. Capturing these fast processes is a big challenge in biology. And showing them not only in 2D but in 3D is — next to the needed high resolution — the second main aspect of modern microscopy. The […]

Materials chemists tap body heat to power ‘smart garments’

Many wearable biosensors, data transmitters and similar tech advances for personalized health monitoring have now been “creatively miniaturized,” says materials chemist Trisha Andrew at the University of Massachusetts Amherst, but they require a lot of energy, and power sources can be bulky and heavy. Now she and her Ph.D. student Linden Allison report that they have developed a fabric that […]

New materials could ‘drive wound healing’ by harnessing natural healing methods

Materials are widely used to help heal wounds: Collagen sponges help treat burns and pressure sores, and scaffold-like implants are used to repair bones. However, the process of tissue repair changes over time, so scientists are developing biomaterials that interact with tissues as healing takes place. Now, Dr Ben Almquist and his team at Imperial College London have created a […]

Inside these fibers, droplets are on the move

Microfluidics devices are tiny systems with microscopic channels that can be used for chemical or biomedical testing and research. In a potentially game-changing advance, MIT researchers have now incorporated microfluidics systems into individual fibers, making it possible to process much larger volumes of fluid, in more complex ways. In a sense, the advance opens up a new “macro” era of […]
