Label-free fluorescence detection of aromatic compounds in chip electrophoresis applying two-photon excitation and time-correlated single-photon counting.

Analytical chemistry

Beyreiss R, Geißler D, Ohla S, Nagl S, Posch TN, Belder D.
PMID: 23944704
Anal Chem. 2013 Sep 03;85(17):8150-7. doi: 10.1021/ac4010937. Epub 2013 Aug 22.

In this study, we introduce time-resolved fluorescence detection with two-photon excitation at 532 nm for label-free analyte determination in microchip electrophoresis. In the developed method, information about analyte fluorescence lifetimes is collected by time-correlated single-photon counting, improving reliable peak...

Cancers (Basel). 2019 Feb 26;11(3). doi: 10.3390/cancers11030276.

Biliary tract cancer is a devastating disease with limited therapeutic options. The involvement of cancer stem cells in biliary tract cancer is likely. Napabucasin is a previously described cancer stem cell inhibitor that is currently being used in clinical...

Rapid prototyping of electrochromatography chips for improved two-photon excited fluorescence detection.

Analytical chemistry

Hackl C, Beyreiss R, Geissler D, Jezierski S, Belder D.
PMID: 24666258
Anal Chem. 2014 Apr 15;86(8):3773-9. doi: 10.1021/ac500793e. Epub 2014 Apr 07.

In the present study, we introduce two-photon excitation at 532 nm for label-free fluorescence detection in chip electrochromatography. Two-photon excitation at 532 nm offers a promising alternative to one-photon excitation at 266 nm, as it enables the use of...

Monitoring on-chip Pictet-Spengler reactions by integrated analytical separation and label-free time-resolved fluorescence.

High-throughput screening for optimal reaction conditions and the search for efficient catalysts is of eminent importance in the development of chemical processes and for expanding the spectrum of synthetic methodologies in chemistry. In this context we report a novel...

Microfluidic chips for chirality exploration.

Analytical chemistry

Nagl S, Schulze P, Ohla S, Beyreiss R, Gitlin L, Belder D.
PMID: 21443215
Anal Chem. 2011 May 01;83(9):3232-8. doi: 10.1021/ac200150w. Epub 2011 Mar 28.

Microfluidic chips applied to the investigation of chirality allow reaction, separation and analysis of minuscule amounts of enantiomeric molecules. Chiral chip technology is employed in fields as diverse as pharmaceutical high throughput screening and deep space exploration missions.
