Brushing up on sensors
(14 Nov 2008)
Jason Locklin and his colleagues from the University of Georgia have developed covalently bound polymer brushes that can bind metal ions when irradiated with UV light. The polymer brushes, containing spiropyran moieties, were synthesised using atom ...

Mechanical calculations for methyl transfer in solution
(13 Nov 2008)
Ian Williams and colleagues at the University of Bath, UK, have demonstrated that kinetic isotope effects (KIEs) for a prototypical SN2 methyl transfer in solution, and in an enzyme active site, show significant variations in magnitude owing to ...

UK fingerprint "developer” can read a letter from its envelope
(12 Nov 2008)
UK scientists have discovered a fingerprint "developer” which can highlight invisible prints on almost any surface – and read the text of a letter just from the envelope it was sent in. Paul Kelly and colleagues at Loughborough University found that ...

Sewing DNA thread with lasers, hooks and microbobbins
(14 Jul 2008)
Japanese scientists have made a micro-sized sewing machine to sew long threads of DNA into shape. The work published in the Royal Society of Chemistry journal Lab on a Chip demonstrates a unique way to manipulate delicate DNA chains without breaking ...
