J. Planar Chromatogr. 21, 77-82 (2008). Ozone can be detected indirectly in TLC or OPLC zones by use of the bioautographic BioArena system and ozone-eliminating molecules (e.g. d-limonene and indigo carmine) in the culture medium. TLC and OPLC of test substances (trans-resveratrol, aflatoxin B1) on silica gel with a variety of mobile phases (e. g. chloroform - methanol 10:1). The developed and dried TLC plates were immersed in a bacterial suspension of Pseudomonas savastanoi for 20 s. Visualization of the chromatograms with MTT was performed either after a a short draining period or after overnight incubation.

J. Planar Chromatogr. 30, 271-274 (2017). HPTLC of the synthetic pyrethroids cypermethrin, deltamethrin, and λ-cyhalothrin on silica gel with n-hexane – acetone 4:1. Detection by spraying with freshly prepared hydralazine solution (37.5 mg in 50 mL 2N sodium hydroxide solution). The hRF value for α-cyano ester pyrethroids was 57.

Part II. Thin-layer chromatographic studies. Analyst III. 707-710 (1986). Examination of o-phthalaldehyde-sulfuric acid as a fluorogenic spray reagent for TLC determination of some indol-3-yl acids. Investigation of the effects of 2-mercaptoethanol or cysteine, UV irradiation and gaseous electrical discharge. o-phthalaldehyde-sulfuric acid associated with an UV pre-irradiation was the best for the compounds examined. o-phthalaldehyde, fluorogenic reagent, indol-3-yl acids

J. Liquid Chromatogr. 12, 3135-3149 (1989). Evaluation of the luminescence detectability of several SBD-thiol derivatives on five different HPTLC layers: cellulose, C-18 silica and silica 40, 60 and 100. Influence of the type of stationary phases dipped with fluorescence enhancers. Discussion of the reasons for the phenomena. Consideration of the time elapsed between plate dipping and measurement as well as the dynamic linearity of the enhancement process. Fluorescence enhancers: Triton X-100 and liquid paraffin.

Thin-layer chromatographic differentiation of nitrones, nitroxide radicals and nitroso amines in mixtures. J. Chromatogr. 663, 127-131 (1994). TLC of title compounds on silica with chloroform (or methanol) - acetone 4:1. Detection by spraying with sodium iodide and subsequently with trifluoroacetic anhydride-sodium iodide reagent. Brown spots appear on white background, stable for more than 20 min.

J. Chromatogr. A, 740, 99-107 (1996). TLC on silica with 1) toluene - ethyl formiate - formic acid 5:4:1, and 2) ethyl acetate - formic acid - water 20:2:1. Detection by dipping into diphenylboric acid 2-aminoethyl ester solution, and by fluorodensitometry. Investigation of the effect of different substances on the intensity and stability of the fluorescence. Comments on the procedure for measurement, and discussion of the correlation between fluorescence and molecular structure.

J. Planar Chromatogr. 14, 210-212 (2001). HPTLC of monocrotophos and other organophosphorus insecticides (malathion, ethyl parathion, methylparathion, fenitrothion fenthion, phorate, dimethoate, phosphamidon, dichlorvos), organochlorine insecticides, carbamate insecticides, pyrethroid insecticides on silica gel in a pre-saturated chamber with chloroform - acetone 7:3. After drying the plate is sprayed with a 20% anhydrous sodium carbonate solution then with 0.5% chloranil (in acetone) reagent. The reagent is selective for monocrotophos among other insecticides.

Phosphorus, Sulfur Silicon Relat. Elem. 184, 1139-1148 (2009). The new TLC system for sulfide ions detection is based on the use of 2,4,6-triphenylpyrylium salts as pre-chromatographic derivatization reagents. The cations L1 (2,4,6-triphenylpyrylium) or LN1 (4-[p-(N,N-dimethylamino) phenyl]-2,6-diphenylpyrylium) were used in the derivatization reactions in a tube or directly on the TLC plate before the developing step. TLC of L1 on silica gel with methanol – dichloromethane 1:5. TLC of LN1 on cellulose with phosphoric buffer (pH 6.0) – acetonitrile – 1,4-dioxane 4:2:1. The detection procedure allows selective and sensitive detection for sulfide anions at several dozen pmol/spot.
