Anal. Chem. 81, 3858-3866 (2009). HPTLC of microcystin LR and nodularin on silica gel with 1-propanol - ethyl acetate - water 3:5:2 with 5 % acetic acid. Detection and quantification by UV spectroscopy at 232 nm and direct identification of separated analytes on the HPTLC plate by IR-MALDI-o-TOF MS. The detection limit was 3-5 ng/zone. For detection of peptides, plates were cut and sprayed with a solution of p-anisaldehyde, followed by heating at 105 °C until purple-blue peptide spots appeared.

Food Control. 68, 310-329 (2016). Review of the methodologies to determine the occurrence of aflatoxin M1 (AFM1) and the fate of AFM1 during processing of milk and dairy products, such as yoghurt and cheeses, since 1996 until today. The review describes the application of TLC and HPTLC in raw and pasteurized milk, feta cheese, yoghurt, white cheese, ice cream and butter.
