Finding a handle to bag the right proteins

Purifying specific protein molecules from complex mixtures will become easier with a simpler way to detect a molecular tag commonly used as a handle to grab the proteins.

To improve health monitoring, simply trip the 'nanoswitch'

Engineered strands of DNA—nanoscale tools called "nanoswitches"—could be the key to faster, easier, cheaper and more sensitive tests that can enable high-fidelity detection of biomarkers indicating the presence of different ...

Separation of DNA and proteins through improved gel electrophoresis

Medical diagnoses and DNA sequencing can be made cheaper, faster and more reliable using a new miniaturized technique for gel electrophoresis based on conducting polymer materials, according to researchers at Linköping University ...

Stiffening the backbone of DNA nanofibers

An international collaboration including researchers from the NIST Center for Nanoscale Science and Technology and the Universidad San Francisco de Quito, Ecuador have fabricated a self-assembled nanofiber from a DNA building ...

Imaging metals within cells: Identifying the proteins that bind

(Phys.org)—Metals such as copper, zinc, and iron are important nutrients to all life. The special properties of these elements that make them so useful in technologies including batteries and catalysts – for example, ...

DNA gripped in nanopores

Molecular biologists, including the cool dudes from CSI, use gel electrophoresis to separate DNA fragments from each other in order to analyze the DNA. A team of researchers under the leadership of Vici winner Serge Lemay, ...
