The growth, covalent functionalization, and subsequent DNA modification of gallium phosphide (GaP) nanorods is presented. Analysis of the nanorods by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) revealed important information regarding their physical properties such as the presence of twinning defects. The nanorods were deposited onto g...

Protein nanofibrils offer advantages over other nanostructures due to the ease in their self-assembly and the versatility of surface chemistry available. Yet, an efficient and general methodology for their post-assembly functionalization remains a significant challenge. We introduce a generic approach, based on biotinylation and thiolation, for the multi-functionalization of protein nanofibrils...

Iodine-catalyzed regioselective sulfenylation of imidazo[1,2-a]pyridines via C(sp(2))-H bond functionalization has been achieved using sulfonyl hydrazides as a thiol surrogate. A library of 3-sulfanylimidazopyridines with broad functionalities was synthesized under metal and oxidant-free practical reaction conditions. This methodology is also applicable for the regioselective sulfenylation of i...

In spite of the diamagnetic behavior exhibited by bulk ZnO and Au, a ferromagnetic-like behavior is induced in nanoparticles of both systems by appropriate surface functionalization. By capping with thiol derivatized molecules, magnetic hysteresis is observed even at room temperature, whereas the magnetization has a very little temperature dependence. Capping induces an alteration of their elec...

1,3-dimercaptopropan-2-ol, a symmetrical di-thiol, has been synthesized and applied as new type of anchor molecule to prepare self-assembled monolayer (SAM) on gold surface. The formed monolayers were studied by cyclic voltammetry, impedance spectroscopy, X-ray photoelectron kinetic capacitance, contact angle measurements. SAM structure depends the adsorption conditions. A short incubation time...

Nucleic acids are important bio-macromolecules in living systems. They are involved in important functions like gene expression and regulation. Nucleoside triphosphates serve as precursors for biochemical synthesis of modified nucleic acids and nucleotide coenzymes. The modification of nucleic acids, particularly at nucleobases, can expand the function and chemical properties of nucleic acid. H...

Syndiotactic 1,2 polybutadiene nanoparticles (volume average diameter 13 nm) were func tionalized in aqueous dispersion by free radical mercaptan addition. By appropriate choice of both water soluble radical initiator andmercaptan concentration, nanoparticles with a degree of functionalization of up to 85% were prepared using 3 mercaptopropionic acid methyl ester and 3 mercaptopropionic acid. O...

Molecular linkers have emerged as an effective strategy to improve electronic transport properties on solution-processed layered materials via defect functionalization. However, a detailed discussion the microscopic mechanisms behind beneficial effects of functionalization is still missing. Here, by first-principles calculations based density functional theory we investigate interconnected MoS2...
