High impact information on Microscopy, Scanning Tunneling

• Here we report scanning tunnelling microscopy studies of cysteine adsorbed to a (110) gold surface, which show that molecular pairs formed from a racemic mixture of this naturally occurring amino acid are exclusively homochiral, and that their binding to the gold surface is associated with local surface restructuring [1].
• A chemically induced dimer configuration was prepared on the silicon (Si) (100) surface and was characterized by scanning tunneling microscopy (STM) and spectroscopy (STS) [2].
• In accordance with the higher degree of disorder observed in scanning tunneling microscopy images of 1-fluorohexane, theoretical simulations show that electrostatic forces associated with the fluorine substituent are sufficiently strong to upset the delicate balance of interactions required for the formation of an ordered monolayer [3].
• Scanning tunneling microscopy imaging of Torpedo acetylcholine receptor [4].
• Two-dimensional ordering of the DNA base guanine observed by scanning tunneling microscopy [5].

Biological context of Microscopy, Scanning Tunneling

• Chiral recognition in dimerization of adsorbed cysteine observed by scanning tunnelling microscopy [1].

• In-situ scanning tunneling microscopy (STM), cyclic voltammetry (CV), and infrared reflection-adsorption spectroscopy (IRRAS) have been used to examine the electrodeposition of gold onto Pt(111) electrodes modified with benzenethiol (BT) and benzene-1,2-dithiol (BDT) in 0.1 M HClO4 containing 10 microM HAuCl4 [11].
