Gold nanoparticles (Au NPs) play a significant role in science and technology because of their unique size, shape, properties broad range potential applications. This review focuses on the various approaches employed for synthesis, modification functionalization nanostructured Au. The catalytic applications enhancement upon Au nanostructures have also been discussed detail. present analysis off...
Well-known surface properties of gold nanoparticles (AuNPs) offer easy surface modification with desired biomolecule, thus enabling them to be used for targeting and imaging of cancer cells/tissues. However, targeting and imaging capability come through after synthesis coating of AuNPs' surface with targeting or imaging molecules. Attempts have been made to conjugate both imaging and targeting ...
A novel concept is introduced for the oriented incorporation of membrane proteins into solid supported lipid bilayers. Recombinant cytochrome c oxidase solubilized in detergent was immobilized on a chemically modified gold surface via the affinity of its histidine-tag to a nickel-chelating nitrilo-triacetic acid (NTA) surface. The oriented protein monolayer was reconstituted into the lipid envi...
This paper describes the fabrication of surfaces with different wettability, superhydrophobic/superhydrophilic, and pH-responsive properties. We used a self-assembled monolayer (SAM) of a dendron thiol as the underlying surface for electrodeposition of gold nanostructures. After this modification with a SAM of n-dodecanethiol or 11-mercaptoundecanol, the surface shows remarkable superhydrophobi...
In order to obtain gold electrode surfaces modified with Human Papillomavirus L1 protein (HPV L1)-derived peptides, two sequences, SPINNTKPHEAR and YIK, were chosen. Both have been recognized by means of sera from patients infected with HPV. The molecules, Fc-Ahx-SPINNTKPHEAR, Ac-C-Ahx-(Fc)KSPINNTKPHEAR, Ac-C-Ahx-SPINNTKPHEAR(Fc)K, C-Ahx-SPINNTKPHEAR, and (YIK)₂-Ahx-C, were designed, synthesize...
A surface modification of interdigitated gold microelectrodes (IDEs) with a doped polypyrrole (PPy) film for detection of dopamine released from populations of differentiated PC12 cells is presented. A thin PPy layer was potentiostatically electropolymerized from an aqueous pyrrole solution onto electrode surfaces. The conducting polymer film was doped during electropolymerization by introducin...
