Characterization of the aggregation-induced enhanced emission of N,N'-bis(4-methoxysalicylide)benzene-1,4-diamine [PDF]
, 2015 © 2015 Springer Science+Business Media New York. N,N′-bis(4-methoxysalicylide)benzene-1,4-diamine (S1) was synthesized from 4-methoxysalicylaldehyde and p-phenylenediamine and it was found to exhibit interesting aggregation-induced emission enhancement ...

Ultra-high resolution imaging by fluorescence photoactivation localization microscopy.
Biophysical Journal, 2006 Biological structures span many orders of magnitude in size, but far-field visible light microscopy suffers from limited resolution. A new method for fluorescence imaging has been developed that can obtain spatial distributions of large numbers of ...

Green fluorescent protein as an indicator of cryoinjury in tissues. [PDF]
, 2013 The fluorescence intensity of Green Fluorescent Protein (GFP) has previously been demonstrated to be an accurate indicator of cellular viability following cryoinsult in individual GFP-transfected cells. In an attempt to ascertain whether GFP fluorescence

Cytogenetic analysis using quantitative, high-sensitivity, fluorescence hybridization.
Proceedings of the National Academy of Sciences of the United States of America, 1986 This report describes the use of fluorescence in situ hybridization for chromosome classification and detection of chromosome aberrations. Biotin-labeled DNA was hybridized to target chromosomes and subsequently rendered fluorescent by successive ...

Entangled-Photon Coincidence Fluorescence Imaging [PDF]
Optics Express 16, 16189 (2008), 2008 We extend entangled coincidence (ghost) imaging to fluorescent samples. Given the entangled photon correlation, one photon of the pair carries information on where the other photon has been absorbed and has produced fluorescence in a sample. Fluorescent molecules serve as ''detectors breaking'' the entanglement.

Experimental determination of tantalum L-shell fluorescence yields and Coster-Kronig transition probabilities [PDF]
arXiv, 2022 Using radiometrically calibrated instrumentation of Physikalisch-Technische Bundesanstalt, the L-shell fluorescence yields and Coster-Kronig factors of tantalum (including the uncertainty budget) were experimentally determined based on transmission and X-ray fluorescence experiments.
