“…UPy moieties can form self-complementary dimers via quadruple hydrogen bonding interaction and have been utilized to prepare self-healable polymer gels. [57][58][59][60][61] The feeding ratio of 1IBDP/ 2IBDP, acrylamide, UPy-MA and MBAA is 1 : 100 : 2.5 : 2. The two gels containing 1IBDP and 2IBDP are simplied as g-1IBDP and g-2IBDP, respectively.…”

“…In this article, we measure the conductance of amino acids by using an STM break junction [17,22,23,24,25,26,27]. Amino acids with different kinds of anchoring groups, including l -alanine, l -methionine, l -aspartic acid, and l -glutamic acid, were measured and compared.…”

The single molecular conductance of amino acids was measured by a scanning tunneling microscope (STM) break junction. Conductance measurement of alanine gives out two conductance values at 10−1.85 G0 (1095 nS) and 10−3.7 G0 (15.5 nS), while similar conductance values are also observed for aspartic acid and glutamic acid, which have one more carboxylic acid group compared with alanine. This may show that the backbone of NH2–C–COOH is the primary means of electron transport in the molecular junction of aspartic acid and glutamic acid. However, NH2–C–COOH is not the primary means of electron transport in the methionine junction, which may be caused by the strong interaction of the Au–SMe (methyl sulfide) bond for the methionine junction. The current work reveals the important role of the anchoring group in the electron transport in different amino acids junctions.

“…In 2015, Hong et al . further investigated the charge transport properties through supramolecular interactions of quadruple hydrogen bonds in ureido pyrimidinedione . These works suggested that the charge transport abilities across supramolecular interaction are quite high and even equal with the covalent interaction in single‐ molecule junctions.…”

Charge transport across the peptide chains is one of the vital processes in the biological systems, so understanding their charge transport properties is an indispensable prerequisite to explain the complex biochemical phenomenon. Here, we review the charge transport mechanism, the influence of the special groups and the experimental conditions on the charge transport through the peptide backbone by employing the single-molecule electrical measurements. Besides, we further review the recent progresses in charge transport properties of supramolecular interaction among the adjacent peptide chains. Finally, we discuss some experimental and theoretical contradictions existing in the charge transport through peptides and provide new inspiration for the future development of the bioelectronics at the single-molecule scale.Haining Zheng (left) received her BEng Degree from Qingdao University of Science and Technology in 2017.
