J. Chromatogr. 473, 287-292 (1989). Presentation of a selective procedure for the detection of nitrones and nitroxide radicals in the presence of amine N-oxides on the TLC plate based on the application of trifluoroacetic anhydride-sodium iodide reagent. Discussion of possible interferences and their elimination.

J. Chromatogr. 596, 271-275 (1992). Postchromatographic derivatization with phenylboric acid, based on its reaction with the diol group to form cyclic boronate.

Anal. Biochem. 239, 223-237 (1996). Presentation of two new fluorescent dyes for detection of proteins in electrophoretic gels using one-step procedures, with the stained protein being excited by UV 300 nm, or at visible wavelengths, and the excitation maxima of 472 nm for the Orange stain and 547 nm for the Red stain. Discussion of the sensitivity by comparison with other staining techniques and their limitation.

J. Planar Chromatogr. 14, 21-23 (2001). TLC of the DIPABTC derivatives of eight monoamines (adrenaline, b-phenylethylamine, histamine, noradrenaline, octopamine, serotonin, and tyramine) on silica gel in a horizontal chamber at 24°C with 15 mobile phases. Higher sensitivity was achieved when the colored derivatives were placed in HCl vapor resulting in deep red-brown spots. Simple and quick TLC method using a newly synthesized derivatization reagent.

J. Liq. Chromatogr. Relat. Technol. 38, 1279-1285 (2015). TLC of Citrus herbal medicines on NaOH-modified silica gel with ethyl acetate - methanol - water 100:17:13, followed by drying at room temperature and second development with toluene - ethyl acetate - formic acid - water 20:10:1:1. Detection by spraying with 1 % aluminium chloride ethanolic solution. The greyscale image captured under UV 365 nm was corrected by removing the quadratic baseline trend of the densitometric curve of every row.

Anal. Chem. 57, 1359-1 362 (1985). Study of the factors affecting signal/noise ratio and detectability of a photothermal deflection densitometer in TLC applications. The detectability of azobenzene, 1.3 ng. Suggestion of Hadamard transform photothermal deflection spectroscopy. Significant parameters are the angle between the TLC plate and the probe laser beam, probe beam offset from the plate, output power of laser pump beam, and chopper frequency.

European Chromatography News 2, 18-21 (1988). Description of some of the many recent innovations like advances in TLC plates, sample application, development techniques and instrumentation for detection, quantification and identification. TLC is described as a sensitive instrumentalized quantitative analytical technique.
