Two pairs of amino-acid functionalized poly（3,4-ethylenedioxythiophene）（PEDOT） derivatives, namely, ...poly（N-（tert-butoxycarbonyl）-L-methionyl（3,4-ethylenedioxythiophene-2＇-yl）methylamide）（L-PEDOT-Boc-Met） and poly（N-（tertbutoxycarbonyl）-D-methionyl（3,4-ethylenedioxythiophene-2＇-yl）methylamide）（D-PEDOT-Boc-Met）; poly（L-methionyl（3,4-ethylenedioxythiophene-2＇-yl）methylamide）（L-PEDOT-Met） and poly（D-methionyl（3,4-ethylenedioxythiophene-2＇-yl）methylamide）（D-PEDOT-Met） were synthesized via chemical oxidative polymerization of corresponding monomers. The structural characterization, spectroscopic properties and thermal stability of these monomers and polymers were systematically explored by FTIR spectra, Raman spectra, XRD spectra, UV-Vis spectra and thermogravimetric analysis. As chiral electrode materials, these polymers were employed to successfully recognize 3,4-dihydroxyphenylalanine（DOPA） enantiomers by cyclic voltammetry（CV） in sulphuric acid solution. The measurement results reveal that the tendency was hetero-chiral interaction between L-PEDOT-Met/PVA/GCE and D-DOPA, D-PEDOT-Met/PVA/GCE and L-DOPA, respectively. Also, the mechanism of chiral discrimination was discussed. All the results implied that the combination of electrochemical molecular recognition technology and chiral PEDOT materials can be a promising approach for chiral recognition and may open new opportunities for facile, biocompatible, sensitive and robust chiral assays in biochemical applications.

Due to their potential applications in physiological monitoring, diagnosis, human prosthetics, haptic perception, and human–machine interaction, flexible tactile sensors have attracted wide research ...interest in recent years. Thanks to the advances in material engineering, high performance flexible tactile sensors have been obtained. Among the representative pressure sensing materials, 2D layered nanomaterials have many properties that are superior to those of bulk nanomaterials and are more suitable for high performance flexible sensors. As a class of 2D inorganic compounds in materials science, MXene has excellent electrical, mechanical, and biological compatibility. MXene‐based composites have proven to be promising candidates for flexible tactile sensors due to their excellent stretchability and metallic conductivity. Therefore, great efforts have been devoted to the development of MXene‐based composites for flexible sensor applications. In this paper, the controllable preparation and characterization of MXene are introduced. Then, the recent progresses on fabrication strategies, operating mechanisms, and device performance of MXene composite‐based flexible tactile sensors, including flexible piezoresistive sensors, capacitive sensors, piezoelectric sensors, triboelectric sensors are reviewed. After that, the applications of MXene material‐based flexible electronics in human motion monitoring, healthcare, prosthetics, and artificial intelligence are discussed. Finally, the challenges and perspectives for MXene‐based tactile sensors are summarized.
The latest research advances in preparation strategies and characterization of MXene‐based tactile sensors are comprehensively introduced and discussed. Meanwhile, their applications in human motion monitoring, healthcare, prosthetics, and artificial intelligence are reviewed.

The low-molecular-weight glutenin subunit (LMW-GS) of wheat is about 1/3 of the amount in seed storage proteins and has great effects on dough extensibility and food processing quality. It has thus ...became one of the main factors for wheat quality improvement. However, resolution of the LMW-GS and the scoring of their alleles by direct analysis of proteins are challenging to work with due to the larger number of expressed subunits and their overlapping mobility with the abundant gliadin proteins. In this paper, scientists reviewed the nomenclature and structure features of LMW-GS, their coding gene loci on chromosomes and allelic variation, the registered genes in Genbank and classification, and their relations with. We also discussed the identification of LMW-GS genes and their development of molecular markers based on the author’s own research results, in order to provide a theoretical basis for using LMW-GS in breeding quality wheat cultivar.
