Nanowire imaging by super resolution optical microscopy
Researchers of NanoLund, in collaboration with the group of Stefan Hell at the Max Planck Institute for Biophysical Chemistry in Göttingen, have published an article in Nano Letters showing that nanowires can be imaged using super resolution optical microscopy. In the article, GaInP nanowires were imaged using ground state depletion at a five fold resolution enhancement compared to confocal microscopy. This method is compatible with biological tissue imaging and is therefore promising for the investigations of cell-nanowire interactions.
The study was done by J. Oracz, K. Adolfsson, V. Westphal, C. Radzewicz, M. T Borgstrom, S. Sahl, C. N. Prinz, and S. W. Hell and the article "Ground State Depletion Nanoscopy Resolves Semiconductor Nanowire Barcode Segments at Room Temperature" in Nano Letters can be found through dx.doi.org/10.1021/acs.nanolett.7b00468
