Study suggests how to build a better 'nanopore' biosensor

Researchers have spent more than three decades developing and studying miniature biosensors that can identify single molecules. In 5 to 10 years, when such devices may become a staple in doctors' offices, they could detect ...

Animal venoms as natural resource for new drugs

Currently there are more than 80 peptide drugs on the global market and about twice as many in clinical development. Due to their beneficial properties, these biomolecules play already an important role in the treatment of ...

Researchers identify genetics behind deadly oat blight

A multi-institution team co-led by a Cornell University researcher has identified the genetic mechanisms that enable the production of a deadly toxin called Victorin—the causal agent for Victoria blight of oats, a disease ...

Fluorescent peptide nanoparticles, in every color of the rainbow

The discovery of green fluorescent protein (GFP), which is made by a jellyfish, transformed cell biology. It allowed scientists to stitch the GFP sequence to proteins from other organisms to trace their movements and interactions ...

Construction kit for custom-designed products

Microorganisms often assemble natural products similar to product assembly lines. Certain enzymes, non-ribosomal peptide synthetases (NRPS), play a key role in this process. Biotechnologists at Goethe University have now ...

Human hazards hamper vampire bat venom research

Vampire bats could hold the key to new treatments for a range of serious medical problems, but researchers have hit a snag accessing the specimens needed to advance their work.

New technique enables spatial separation of peptide structures

A team of scientists at DESY and Universität Hamburg has reached another milestone towards the direct imaging of individual biomolecules: the group led by Jochen Küpper from the Center for Free-Electron Laser Science developed ...

Scientists develop broad-spectrum inhibitors of influenza virus

A team of researchers from The Scripps Research Institute (TSRI) and Janssen Research & Development (Janssen) has devised artificial peptide molecules that neutralize a broad range of influenza virus strains. Peptides are ...
