AbstractUnlike the highly ordered Self-Assembled Monolayers (SAMs) formed on flat gold surfaces, those on gold nanoparticles radiate from a roughly spherical center and are amorphous in structure. One result of this structural motif is that the strength of intra- monolayer non-covalent interactions, such as Φ-stacking and hydrogen bonding, are a function of the distance of the recognition element from the colloidal core. We present here an exploration of these phenomena in amide functionalized thiols in MPCs where the amide functionality position was varied in the alkane chain. [1]

AbstractSupramolecular chemistry is one of the exciting branches of chemistry where non-covalent interactions between molecules and the ensuing supramolecular structures have been studied for various applications. The present review provides a comprehensive outlook on the applications and potentials of supramolecular chemistry in corrosion and biofouling prevention. Reported works associating supramolecular chemistry with corrosion are systematically discussed under two sections: (i) surface coatings and (ii) corrosion inhibitors that include supramolecular polymers, host-guest inclusion compounds, organic-inorganic hybrid materials, and supramolecular structures of graphene, crown ethers, self-assembled monolayers, etc. Different strategies for making antifouling surfaces based on block copolymers/gel systems, host-guest systems, and metal-organic structures are briefed. Cyclodextrin and mesoporous silica-based host-guest systems are extensively discussed, as they are the most prominent materials of current research interest. Future potentials for developments are presented. The review is expected to be beneficial to enhance supramolecular chemistry-related research and development in corrosion and biofouling prevention.

AbstractIn this paper, we present the electrochemically programmed release of immobilized IgG protein molecules that have been attached to gold coated surfaces via a thiol-gold linkage. Fluorescence microscopy has been used to image the release of fluorescently tagged IgGs in phosphate buffered saline. In this technique, the reductive desorption of self-assembled monolayers is employed for the release of proteins, which are immobilized on the surface either by non-covalent or covalent interactions. The voltage applied for the release of proteins is in a range of -1.5V to -60V.
