Nanopores make portable mass spectrometer for peptides a reality

University of Groningen scientists have developed nanopores to directly measure the mass of peptides. Although the resolution needs improvement, this proof of principle shows that a cheap and portable peptide mass spectrometer ...

RNA microchips

Ribonucleic acid (RNA) is, along with DNA and protein, one of the three primary biological macromolecules and was probably the first to arise in early life forms. In the "RNA world" hypothesis, RNA is able to support life ...

Researchers find value in unusual type of plant material

An ideal biorefinery would turn renewable crops into a variety of fuels and products with little waste. A significant challenge in realizing this vision is what to do with lignin, a fibrous and difficult-to-break-down material ...

3-D inks that can be erased selectively

3-D printing allows for the efficient manufacture of complex geometries. A promising method is direct laser writing—a computer-controlled, focused laser beam acts as a pen and produces the desired structure in a photoresist. ...

Custom sequences for polymers using visible light

Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. By simply ...

Metal-organic frameworks used as looms

Researchers of Karlsruhe Institute of Technology (KIT) have made major progress in the production of two-dimensional polymer-based materials. To produce cloths from monomolecular threads, the scientists used SURMOFs, i.e. ...
