Quantum dots combined with antibodies as a method for studying cells in their native environment
DNA origami could lead to nano 'transformers' for biomedical applications
If the new nano-machines built at The Ohio State University look familiar, it's because they were designed with full-size mechanical parts such as hinges and pistons in mind.
Stomach acid-powered micromotors get their first test in a living animal
Researchers at the University of California, San Diego have shown that a micromotor fueled by stomach acid can take a bubble-powered ride inside a mouse. These tiny motors, each about one-fifth the width ...
Engineering self-assembling amyloid fibers
Nature has many examples of self-assembly, and bioengineers are interested in copying or manipulating these systems to create useful new materials or devices. Amyloid proteins, for example, can self-assemble ...
Nanoshuttle wear and tear: It's the mileage, not the age
As nanomachine design rapidly advances, researchers are moving from wondering if the nanomachine works to how long it will work. This is an especially important question as there are so many potential applications, ...
One nanoparticle, six types of medical imaging
It's technology so advanced that the machine capable of using it doesn't yet exist.
Researchers introduce improved injectable scaffold to promote healing
Rice University scientists have found the balance necessary to aid healing with high-tech hydrogel.
New triggered-release mechanism could improve drug delivery
More efficient medical treatments could be developed thanks to a new method for triggering the rearrangement of chemical particles.
Gold nanoparticles show promise for early detection of heart attacks
NYU Polytechnic School of Engineering professors have been collaborating with researchers from Peking University on a new test strip that is demonstrating great potential for the early detection of certain ...
Scientists use 'NanoVelcro' and temperature control to extract tumor cells from blood
(Phys.org)—An international group led by scientists at UCLA's California NanoSystems Institute has developed a new method for effectively extracting and analyzing cancer cells circulating in patients' blood.
'Glowing' new nanotechnology guides cancer surgery, also kills remaining malignant cells
Researchers at Oregon State University have developed a new way to selectively insert compounds into cancer cells - a system that will help surgeons identify malignant tissues and then, in combination with ...
Holes in valence bands of nanodiamonds discovered
Nanodiamonds are tiny crystals only a few nanometers in size. While they possess the crystalline structure of diamonds, their properties diverge considerably from those of their big brothers, because their ...
Nano scale research could yield better ways to identify and track malignant cells
As a young physicist in the former Soviet Union, Igor Sokolov studied the biggest of the big—the entire universe. Now, as a professor of mechanical engineering at Tufts, he's focused on the tiny, the nano. ...
Promising use of nanodiamonds to kill chemoresistant cancer stem cells more effectively
A study led by the National University of Singapore (NUS) found that attaching chemotherapy drug Epirubicin to nanodiamonds effectively eliminates chemoresistant cancer stem cells. The findings were first ...
