Review of enzymatic protein hydrolysis, including standard and conventional techniques and their applications and insights into new strategies of detection and characterization of bioactive peptides. The paper described HPTLC methods coupled with bioassays in effect-directed analysis (EDA) to detect the bioactivities of peptides.

Food Chem. 132937 (2022). Review of TLC assays, including cellular, enzymatic and chemical, and their application for effect-directed food-related analysis, in the last five years. TLC assays for the analysis of antioxidants and for the detection of enzyme inhibitors were described. Microorganism based TLC assays for the detection of antimicrobials, aflatoxins and estrogenic compounds were also presented. TLC methods for the detection of bisphenol and dioxin-like chemicals were described. 

Food Chem. 134216 (2023). Review of emerging techniques for the analysis of animal-derived food, including HPTLC methods for authenticity and origin tracing of honeys. In particular, methods for the determination of phenols in honey was cited using principal component analysis as discrimination model. 

J. Planar Chromatogr. 35, 229-241 (2022). Review of the advances, limitations and challenges faced by the application of HPTLC for lipidomic analysis. The paper described methods for the separation of phospholipids (PL) and/or sphingolipids (SL) on silica gel HPTLC plates from different samples in lipidomic studies, including matrices and development conditions. HPTLC methods for separating lipid classes and subclasses, combined with semi-quantification by UV‒FL densitometry and mass spectrometry were also described. HPTLC and genetic knockouts was also discussed as an emerging field. 

Anal Chim Acta 1180 (2021) 338644. Review with 120 references on HPTLC combined with effect-directed assays (EDA) and high-resolution mass spectrometry (HRMS). Brief introduction of status quo of these emerging technologies, involving targeted, untargeted and predictive strategies. Hyphenated HPTLC has great potential for solving pressing analytical questions because it provides information on the effects from individual compounds in complex or natural samples, it allows separation in parallel, and the separation is combined with effect-directed detection using enzymatic or biological assays, capable to select the important compounds in a complex sample for further characterization by HRMS. Overview of emerging hyphenated technologies driven by HPTLC, including non-target high-throughput 8D hyphenation, minimum requirements for sample preparation and comprehensive effect evaluation, agonistic and antagonistic fast effect detection, identifying multi-potent or multi-modulating compounds and simulated on-surface digestion or metabolization for study of biotransformation. HPTLC is a versatile, creative and flexible open-format technique with the benefits of super-hyphenation, minimum requirements for sample preparation, detection of multi-modulating compounds or agonistic versus antagonistic effects, and miniaturization of on-surface metabolization. Discussion of the potential offered by the miniaturized open-source LabToGo system.
