J. Planar Chromatogr. 29, 88-98 (2016). Literature review (1994-2015) of the use of surfactants as mobile phase modifiers for the analysis of organic and inorganic compounds by TLC. The review showed that individual surfactants (cationic, anionic and non-ionic) as well as mixed surfactants (ionic and non-ionic) have been routinely used.

J. Planar Chromatogr. 21, 315-323 (2008). The role of the mobile phase in controlling selectivity for adsorption chromatography - with either thin-layer plates or columns - is reviewed and expanded. The use of different solvent mixtures of varying selectivity in normal-phase chromatography is now on a firm theoretical and practical basis. The choice of a more polar component (B-solvent) of a binary solvent mixture (A/B) largely determines relative retention and resolution. Maximum differences in selectivity are achieved by the use of two mobile phases where the B-solvent is either very polar (requiring a lower % B for desirable values of k) or relatively nonpolar (requiring a higher % B).

B. Fried, R. Toledo (Eds): Biomphalaria snails and larval trematodes. Springer 20119. Chapter 4. This book chapter reviews TLC, HPTLC and other methods for the analysis of larval trematodes from Biomphalaria snails. The analysis of different classes of organic compounds is described: neutral and polar lipids, glycolipids, lutein, beta-carotene, sugars and amino acids. Various TLC and HPTLC phases and developing solvents were used.

J. Chinese Trad. Patent Med. 36 (3), 589-592 (2014). TLC has many advantages: one-time use of stationary phase so often no sample clean-up is needed, wide selection range of the stationary and mobile phase, all separated compounds are stored on the plate for further analysis or detection, etc. Therefore, TLC has been widely applied to various fields, particularly, the quality control of TCM, which is complex. The modernization of TCM mainly relies on modern separation technology. However, the peak capacity of conventional TLC is limited and a more advanced technology, two-dimensional TLC (2D-TLC) emerged. This summary presents a review on 2D-TLC with 26 references, including classification (e.g. 2D-TLC on single absorbent, 2D-TLC on twin absorbent, and 2D-graft TLC), image processing technology of chromatograms using specialized software for further qualitative and quantitative analysis, in-situ hyphenated technology of 2D-TLC with desorption electrospray ionization mass spectrometry (DESI-MS) etc.

J. Liq. Chromatogr. Relat. Technol. 39, 385-393 (2016). Review of the new plates that have been commercialized, mainly silica gel and bonded silica gel-prepared plates, including plate sizes, binders, fluorescent indicators, plate thickness, multi-layer plates, channeled plates and sample location in the sorbent layer. New experimental synthesis routes to prepare ultra TLC plates were also reviewed. _x000D_

Trends Anal. Chem. 87, 1-18 (2017). This review described the application of nanocellulose in analytical chemistry, including the use of electrospun cellulose acetate nanofibers as separation media in TLC for steroids in medical products. These nanofibers were resistant to protic solvents and some non-polar solvents. Interestingly, thinner plates were obtained using such nanofibers, lowering the limit of detection when compared with commercial silica plates.

Trends Anal. Chem. 90, 1-13 (2017). Review of surface-enhanced Raman spectroscopy combined with other techniques to improve characterization, including TLC-SERS to improve SERS sensitivity by eliminating interference from a mixture. TLC-SERS application included discriminating contaminants or toxicants in real-life samples, drugs and biomarker in body fluids, synthetic dye mixtures, and products of a chemical reaction system.

Food Control 90, 152-165 (2018). Review of methods for the analysis of honey adulterants, including the application of TLC and HPTLC for the detection of fructose and sucrose syrups.
