Update (11/06/2013): the link to the raw data on Francesco Stellacci does not work anymore; here is a mirror of the files that were released last month.
STM Image Analysis
In recent months there has been a controversy on the interpretation of some of the STM work done in our group on gold nanoparticles coated with organic molecules. To tackle this issue, we have released a large subset of this work to outside experts for independent analysis. This process having now come to an end, we are releasing to the public domain our raw data, together with tiff files of the images illustrating what is present in the raw data, as well as some representative line scans. The material is available for download at:
(for old browsers:
Please note that the tiff files were produced solely for the purpose of making possible the visualization of the data to people who do not have access to scanning probe software.
As stated previously, science is a process where knowledge is built with time and often learning comes from error. By no means do we claim that the data put online are perfect or flawless. We do stand by the conclusions of our papers.
Hopefully soon, there will be more data about STM of mixed ligand nanoparticles on the scientific literature. This we believe is the place where scientific debates should take place.
On the last point, I respectfully disagree: the places where scientific debates should take place include the coffee areas of any good scientific institutions, conferences, journals, and certainly, blogs. You can expect comments on the data released today on this blog in the next few days.
