Seized ecstasy pills: infrared spectra and image datasets (low resolution jpg)
<p>According to the World Drug Report 2020, cocaine and ecstasy are the most consumed stimulant drugs, with 19 and 27 millions estimated users in 2018. Unsurprisingly, large efforts are being made to design fast and cost effective analytical methods to track and monitor the distribution networks of these synthetic drugs. Here we share two datasets of ecstasy pills seized in the north-east of Switzerland between 2010 and 2011. The first contains 621 forensic grade images of pills, while the second one consists of 486 mIR spectra. While both sets are not covering the same seizure, both provide high quality data with orthogonal information to evaluate clustering and dimension reduction methods.</p> <p>High resolution jpg files can be found here: 10.5281/zenodo.4124562</p>

Nonetheless, low localization probabilities have been reported in several MINFLUX studies, and a broader use of less bright and photostable fluorophores, including near-infrared (NIR) fluorophores has been difficult to realize. In this work, we identified fluorophore blinking as a main cause of erroneous (and dismissed) fluorophore localizations in MINFLUX imaging and devised strategies to overcome these effects. We systematically studied the blinking/switching properties of cyanine fluorophores emitting in the far-red or NIR range, over typical time scales (µs-10ms), sample and excitation conditions used in MINFLUX imaging. Subsequent simulations of representative MINFLUX localization procedures showed that trans-cis isomerization, and in particular photo-reduction of the fluorophores, can generate significant localization errors. These localization errors, however, could be suppressed by balanced redox buffers and repetitive excitation beam scans. Implementing these strategies, and replacing the slower, intrinsic switching of the fluorophores needed for the localization by transient binding of fluorophore-labelled DNA strands to complementary DNA strands attached to the targets (DNA-PAINT), we could for the first time demonstrate NIR-MINFLUX imaging with nanometer localization precision. This work presents an overall strategy, where fluorophore blinking characterization and subsequent simulations make it possible to design optimal sample and excitation conditions, opening for NIR-MINFLUX imaging, as well as for a broader use of fluorophores in MINFLUX and related SRM studies.</p> <p>Acknowledgements:</p> <p>This study was supported by the European Union's Horizon 2020 research and innovation program under grant agreement 101017180 (NanoVIB).</p> <p> </p> <p><strong>Files with raw data on which the manuscript is based are grouped into folders according to the figures/tables in the manuscript where the extracted results are presented.
