Self-Assembled Monolayers on Metal and Oxide Surfaces
This community investigates the chemistry and physics of molecular layers that organize themselves on solid surfaces, primarily to control electron transfer, create stable interfaces for sensors, and model biological membranes.
The work centers on the formation and characterization of self-assembled monolayers (SAMs) on gold, silver, and metal oxide substrates like tin oxide and indium tin oxide. Recurring themes include the use of phosphonic acids and thiols to anchor molecules, the study of electron and charge transport through these layers, and the application of these interfaces in electrochemical detection and lipid bilayer modeling. Methods frequently involve atomic force microscopy, spectroscopy, and thin-film deposition to analyze how molecular structure affects surface properties and interfacial stability.
The largest share of the community's output is found in gold research, accounting for 1.1% of all gold-related papers tracked, with 2,062 papers in this group. Silicon and silver research also contribute significantly, with 470 and 392 papers respectively.
The community comprises 6,299 papers, published most frequently in Langmuir, the Journal of Electroanalytical Chemistry, and the Journal of the American Chemical Society.
Recent work continues to focus on the fundamental mechanisms of electron transfer in biointerfaces, such as gold nanoparticle-cytochrome c systems, and the development of stable aromatic monolayers on silver surfaces. Newer studies also explore the use of SAMs to enhance interfacial adhesion in electronic packaging and to improve the efficiency of organic light-emitting diodes.
