Simon Hadlington, writing for Chemistry World, reports on our new paper:
A simmering controversy over whether certain nanoparticle structures are merely instrument artefacts has boiled over into a bitter dispute, with a senior scientist alleging that he has become the victim of a personal vendetta, something that is strongly denied by researchers on the other side of the argument.
A significant section of the report deals with such accusations. These are not new. More interestingly, given the very small number of scientists who have expressed a public view on the controversy, it was notable to read the following from Paolo Samori, from the University of Strasbourg:
In my laboratory we have imaged Professor Stellacci’s particles and found that these particles indeed have stripes on them. The images show clear features that are invariant with imaging parameters (scan rate, scan angle, feedback loop, etc) and hence they can ascribe to true tip sample interactions […] (he then goes to discuss power spectral analysis, this is thoroughly address in Stirling et al, e.g. see fig 10)
I would like to invite Prof Samori to share these images “that indeed have stripes on them”, e.g. using FigShare. In the meantime, we can only relie on the published evidence. To my knowledge, the only image of stripy (?) nanoparticles published coming from Samori’s lab is from Biscarini et al and is reproduced below next to stripy nanoparticles from the original 2004 Jackson et al paper.
Reactions to this 2013 Biscarini et al were somewhat incredulous:
Mathias Brust: “And yet there are stripes”
Quanmin Guo: “Where are the stripes”
Philip Moriarty: “The Emperor’s new stripes“
