DNA can fold into complex shapes to execute new functions

DNA can mimic protein functions by folding into elaborate, three-dimensional structures, according to a study from researchers at Weill Cornell Medicine and the National Heart, Lung, and Blood Institute, part of the National ...

Brighter fluorescent markers allow for finer imaging

Researchers at the McKelvey School of Engineering at Washington University in St. Louis have pioneered a new technique that will enable higher-resolution imaging of very small objects like neurons. The technique, which improves ...

Lipid vesicles transmit luminous or electrical signals

Liposomes are small spherical vesicles with walls comprising two layers of lipids and containing an aqueous core. These artificial structures have been developed for drug delivery or as carriers of active substances in cosmetic ...

Bottle-brush design enhances cellular imaging

The bottle brush, with its long stalk and dense spray of plastic bristles, is the unsung hero of kitchens everywhere, fitting through the narrow necks of water bottles and vases and into the hard-to-reach interiors of mugs ...

Polymer-based optical fiber for visualization of material stress

Fiber-optic strain sensing is known for its ability to monitor large areas. However, most types of fiber-optic strain sensors require spectrum analysis instruments, which drastically increases the overall cost of sensor systems. ...

New fluorophores could help fight cancer

Scientists from the Ural Federal University and the Ural Branch of the Russian Academy of Sciences have created new fluorescent chemical compounds (fluorophores) for photodynamic therapy of cancerous tumors, the latest method ...
