Spontaneously organized molecular assemblies. 3. Preparation and properties of solution adsorbed monolayers of organic disulfides on gold surfaces
TLDR
In this article, the spontaneous organization of structurally complex organic disulfides on polycrystalline gold substrates has been shown to achieve very high coverages, approaching that equivalent to the bulk phase densities of the adsorbate molecules.Abstract:
This paper shows that stable, oriented, polyfunctional organic monolayers can be prepared by the spontaneous organization of structurally complex organic disulfides on polycrystalline gold substrates. Chemisorption proceeds to very high coverages, approaching that equivalent to the bulk-phase densities of the adsorbate molecules. The bonding to the surface is also highly specific, inasmuch as the chemisorption of the disulfide moiety is favored greatly over a wide range of other functionality. This latter feature allows the ready preparation of a broad variety of organic surfaces with well-defined microscopic and macroscopic characteristics. Several representative examples of monolayer films are described, their chemical and thermal properties explored, and their structures characterized by several techniques including infrared and photoelectron spectroscopies.read more

Formation and Structure of Self-Assembled Monolayers.
TL;DR: Monolayers of alkanethiolates on gold are probably the most studied SAMs to date and offer the needed design flexibility, both at the individual molecular and at the material levels, and offer a vehicle for investigation of specific interactions at interfaces, and of the effect of increasing molecular complexity on the structure and stability of two-dimensional assemblies.

Quantitative determination of surface concentration of protein with surface plasmon resonance using radiolabeled proteins
TL;DR: In this article, a methodology to correlate the absolute surface concentration of protein to the surface plasmon resonance (SPR) response is described, and the thickness and the optical constants for each layer on the sensor chip used were determined with different optical techniques.

TL;DR: In this paper, a method for detecting a nucleic acid is described. The method comprises contacting the nucleic acids with one or more types of particles having oligonucleotides attached thereto, and a detectable change (preferably a color change) is brought about as a result of the hybridization of the oligon nucleotides on the nanoparticles to the nucleus.

TL;DR: Inspired by the tobacco mosaic virus, a dumbbell-shaped, oligo(phenylene ethynylene) template is used to control the length of a PA nanofiber self-assembly (<10 nm) and shows the potential for pitch control using trans-to-cis photoisomerization of a terminal azobenzene group.
