Red, far-red, and near infrared photoswitches based on azonium ions.
نویسندگان
چکیده
Azonium ions formed by p-amino substituted azo compounds with both ortho- and meta-methoxy substituents exhibit strong absorbance in far-red and near infrared spectral region. The compounds undergo robust photoswitching in aqueous solution and exhibit a range of thermal relaxation rates from 10 μs-100 ms.

متن کاملComparative study reveals better far-red fluorescent protein for whole body imaging
Genetically encoded far-red and near-infrared fluorescent proteins enable efficient imaging in studies of tumorigenesis, embryogenesis, and inflammation in model animals. Here we report comparative testing of available GFP-like far-red fluorescent proteins along with a modified protein, named Katushka2S, and near-infrared bacterial phytochrome-based markers. We compare fluorescence signal and s...

In this study, the adsorption of hexavalent chromium and zinc ions from the solution is investigated by raw red mud and mechanical-chemical activated red mud along with the possibility of selective reclamation of these ions from the solution. The mechanical-chemical activation of red mud was done by employing high-energy milling and subsequent acid treatment with HNO3. Raw red mud (RRM) and mec...

In this study, 1200 images and catalogues of M33 spiral galaxy taken by WFCAM camera at UKIRT telescope in J, H and K bands. Cross correlation methods were employed to identify stars in overlapping regions from among images taken in different dates. Careful astrometric and photometric analysis was made to calibrate stellar positions and magnitudes using their 2MASS near infra red survey. The fi...
