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.

J. Planar Chromatogr. 35, 643-646 (2022). HPTLC of amitraz in visceral tissue on silica gel with hexane - acetone 4:1. 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. Liq. Chromatogr. Relat. Technol. 41, 1052-1065 (2019). Review of the following topics for the period of November 1, 2016 to November 1, 2018: sample preparation for TLC pesticide analysis; lipophilicity and retention studies for the study of biological activity; new reagents for pesticide detection; HPTLC-effect directed analysis on the surface of the layer; TLC-Raman spectrometry for the analysis of thiabendazole, triazophos, and phosmet residues; TLC analysis of radiolabeled pesticides; methods for the separation, detection, and qualitative and quantitative determination of pesticide residues; determination of pesticides in commercial products and the use of TLC for pesticide degradation studies. The review highlighted the isolation, characterization, and determination of less hazardous and less toxic biopesticides from plants, bacteria, fungi, and soil as the most active application area of pesticide TLC today.

J. Planar Chromatogr. 32(1), 51-53 (2019). TLC of amitraz in visceral tissues (stomach, intestine, liver, spleen, and kidney) on silica gel with hexane - acetone 4:1. Detection by spraying with 10 % sodium hydroxide solution, followed by heating at 80 °C for 10 min. The plate was then removed, kept to attain room temperature and sprayed with 5 % chloranil solution. The hRF values were between 49 and 51. The zones were stable for 8 h.

J. Agric. Food Chem. 33, 757-763 (1985). TLC of arsenite, arsenate, disodium methane arsenate on cellulose with ethyl acetate - acetic acid - water 3:2:1 and phenol - water - NH3 400:99:1 against standards. Confirmation after scraping by AAS.

J. Chromatogr. 467, 321-326 (1989). TLC of bencetonium chloride residue in fish products on silica with butanol - acetic acid - water 4:1:1. Detection by spraying with a reagent consisting of 3 mL 10% aqueous hexachloroplatinic (IV) acid mixed with 97 mL water and 100 mL 6% aqueous KI.

J. Chromatogr. B, 661, 327-333 (1994). TLC after derivatization with 1-methylimidazole - acetonitrile 1:1 and trifluoroacetic anhydride - acetonitrile 1:1 on silica with hexane - acetone - decane - methanol 59:30:10:1. Detection under UV 366 nm. Detection limit 1-2 ng.

Chinese J. Chromatogr. (Sepu) 22 (3), 296-297 (2004). TLC of rhodojaponin III on silica gel with chloroform - methanol 9:1. Detection by spraying with 10 % H2SO4 in ethanol and heating. Identification by comparison with the standard. Quantification by densitometry at 550 nm. Validation of the method by investigating its linearity range (0.1-4.0 µg/spot, r=0.997), precision (RSD=1.30-3.34 %, n=8), and recovery (95.4-101.5 %, RSD=1.97 %, n=5).
