Peptide-mimetic metallohelices bind Alzheimer protein and extend life in an insect model
More electronic materials opened up with new metal-organic framework
Research published today in Nature Communications shows how high photoconductivity and semiconductor behaviour can be added to MOFs - which already have a huge international focus for their applications in gas storage, sensing and catalysis.
The new work, conducted by Universities in Brazil, the United Kingdom and France – including researchers at Warwick’s Department of Chemistry - found that the new MOF has a photoresponsivity of 2.5 × 105 A.W-1
The work has been highlighted in a press release.
Scott, Fox and Gibson develop 'metallohelical antifreezes'
A collaboration between the Fox, Scott and Gibson groups has been published in the Journal of the American Chemical Society. The team were inspired by how small helical antifreeze proteins in Nature enable extreomophiles to survive low temperatures, where other species would not survive. Rather than using traditional peptide/protein chemistry, the team used self-assembled metallohelicates which have similar dimensions to a small alpha helix, and found some which were remarkably potent at stopping ice crystal growth ; a major technological challenge in applications from wind farms, to aircraft to cryopreservation. Modelling studies showed that the underlying activity could be linked the patches of hydrophobicity (water liking) and hydrophobicity (water hating).
