J. Planar Chromatogr. 36, 433-438 (2023). HPTLC of synthetic cannabinoids AM2201 (1), CP-47,497 (2), and JWH-018 (3) in seized samples on silica gel with cyclohexane - diethylamine 9:1. Quantitative determination by absorbance measurement at 280 nm for (2) and 315 nm for (1) and (3). The hRF values for (1) to (3) were 26, 73 and 55, respectively. Linearity was between 2 and 14 µg/zone for (3), 5 and 35 µg/zone for (1) and 50 and 350 µg/zone for (2). The intermediate precision was 23.0 % for (1), 16.6 % for (2) and 7.5 % for (3). The LOD and LOQ were 5.6 and 16.9 µg/zone for (1), 0.7 and 2.2 µg/zone for (2) and 1.9 and 5.6 µg/zone for (3). Average recovery was 84.0 % for (1), 105.1 % for (2) and 107.1 % for (3).
PLoS ONE 18(10), e0292514 (2023). Samples were 8 glycolipids, either sialylated or not; the two main examples were monosialotetrahexosylganglioside (GM1) and gangliotetraosylceramide (= asialo-GM1 = ASGM1). TLC on silica gel with chloroform – methanol – water – acetic acid 300:200:30:1, followed by air-drying. Visualization of glycolipids by spraying 5-methylresorcinol solution (0.2 % in 2 M sulfuric acid), followed by 5 min heating at 110°C. For immunostaining, underivatized chromatograms were immersed into a blocking gel (1% gelatin, 1% polyvinylpyrrolidone and 1mM EDTA in phosphate-buffered saline solution (PBS)), followed by immersion into a solution of monoclonal (50 ng/mL) or polyclonal (1:1,000) anti-ASGM1 antibodies purposedly produced in rabbits. After 1h reaction at room temperature, the layers were washed thrice with T-PBS (0.05 % Tween 20 in PBS) and horseradish-peroxidase-conjugated anti-rabbit IgG (1:40,000) was added. After washing thrice with T-PBS, the TLC sheets were incubated in substrate solution (tetramethylbenzidine). Blue spots indicated the glycolipids bound by the antibody. In this TLC assay, each of the five monoclonal antibodies (as well as the polyclonal serum) was specific to ASGM1 (unsialylated), whereas in ELISA (enzyme-linked immunosorbent assay) at the same concentrations three of them displayed partial cross-reactivity towards GM1, GM3 or GD1b, which are sialylated glycolipids.

HPTLC of 60 pesticides (1), six plant protection products (2), tomato (3) and grape and wine samples (4) on silica gel with n-hexane - ethyl acetate 5:1, n-hexane - toluene - ethyl acetate 4:1:1 for (2), n-hexane - toluene - ethyl acetate 5:1:1 for (3) and n-hexane - ethyl acetate 5:1 for (4). Documentation in fluorescence mode at 366 nm. pYES bioassay application by dipping into a citrate phosphate buffer, followed by drying and dipping into yeast cell suspension, followed by incubation at 30 °C for 3 h. After drying, the chromatogram was immersed into a MUG solution, followed by incubation at 37 °C for 1 h. Detection at FLD 366 nm/ > 400 nm.
Anal. Bioanal. Chem. https://doi.org/10.1007/s00216-023-04820-6 (2023). HPTLC of bisphenols in complex mixtures such as six tin can migrates (1), five thermal papers (2), and eleven botanicals (3) on silica gel with toluene - ethyl acetate 6:1 for (1), n-hexane - ethanol - ethyl acetate 40:3:3 for (2) and ethyl acetate - toluene - methanol - water 16:4:3:2 for (3). Documentation under white light illumination, UV 254 nm and FLD 366 nm. Biological detection by spraying with Arxula adeninivorans yeast cell suspension, followed by incubation at 37 °C for 2 h. After drying in a cold stream, the plate was sprayed with the luciferin substrate solution and bioluminiscence was recorded.
Trends Anal. Chem. 165, 117156 (2023). Review of the use of radiolabeled pesticides to track nanoformulations in biological and environmental scenarios and the application of TLC for evaluating the mobility and degradation of pesticides and nanopesticides. The paper described TLC as tool to quantify the metabolites generated in the biodegradation study.

Detection by spraying with 10 % sodium hydroxide solution, followed by heating at 80 °C for 10 min. The plate was then removed and kept for attaining room temperature, followed by spraying with freshly prepared sodium nitrite (1%) in acidic media. Right after, alkaline solution of curcumin (1% in sodium hydroxide solution) was sprayed. The hRF value for amitraz was 63.
J. Agric. Food. Chem. 70, 10886-10898 (2022). HPTLC of 81 veterinary drugs from 6 different groups (glucocorticoids, anthelmintics, antiparasitics, coccidiostats, nonsteroidal anti-inflammatory drugs, and antibiotics) in 4 different matrices (honey, pig muscle, cow milk, and chicken eggs) on silica gel with acetonitrile - ammonia - ethanol 13:4:3 up to 80 mm and then in the reverse direction with methanol - acetonitrile - ethanol - ammonia 6:2:1:1 up to 45 mm. After each step, the plates were automatically dried in a cold stream of air for 3 min. Detection under UV light at 254 nm and fluorescence light detection (FLD) at 366 nm. Zones were eluted from the plate using a fully automated auto TLC-LC-MS interface for further analysis by high-resolution tandem mass spectrometry. Most veterinary drugs except penicillins and cephalosporins were detected at the 5 μg/kg level in pig muscle, cow milk, and chicken eggs and 25 μg/kg level in honey.
