David Paramelle’s paper on using gold nanoparticles stoichiometrically functionalised with a peptide that recognises sphingolipids has just been published in Advanced Healthcare Materials (Publisher’s site; Pubmed)

The paper is the classic “Sunday afternoon” project, which arose through discussions with Rachel Kraut at NTU.

As ever, a lot more than Sunday afternoons ended up being put into the paper, because David had to develop some new approaches. Particularly nice was the purification of nanoparticles functionalised with the sphingomyelin-binding peptide (called “SBD”) from non-functionalised nanoparticles. This is a key step for the preparation of nanoparticles carrying just one functional peptide or group. Hitherto, we have happily had affinity tags as the functional group, which allows for affinity chromatography (examples here, here and here). (more…)
