The reversible oriented immobilization of proteins on solid surfaces is a prerequisite for the investigation of mol. interactions at interfaces or the construction of supramol. assemblies. We demonstrate a generally applicable method using a synthetic chel ...
This thesis work focuses on impact and diffusion processes as well as equilibrium positions of a metal deposited on a surface. The metal is deposited in the form of clusters containing n atoms in a controlled way. Gold or silver clusters cations (Au+n and ...
A chimeric TASP (Template Assembled Synthetic Proteins) mol., consisting of a 4-helix bundle motif and an antibody recognition site, has been covalently attached to a gold surface. The reversible antibody binding to the self-assembled monolayer as monitore ...
Methods and app. to study biol. mols. or biol. components at or in self-assembled monolayers (SAMs) on metal surfaces such as gold in aq. environments using attenuated total internal reflection Fourier transform infra-red (ATR-FTIR) spectroscopy are descri ...
(Ecole Polytechnique Federale de Lausanne, Switz.).1999
The authors present the results on specific and non-specific protein binding to the self-assembled chelator thioalkane layer and its dependence on the transition metal ion used. [on SciFinder (R)] ...
A novel two-step method was developed to prep. gold nanoparticles on boron-doped diamond (BDD) electrode. It consisted of sputter deposition of max. 15 equiv monolayers of gold, followed by a heat treatment at 400-600 Deg in air. The as-sputtered gold depo ...
A bifacial topological template exhibiting metal-binding sites and thioalkane chains has been incorporated into self-assembled monolayers and immobilised on gold surfaces: These systems allow for the detection of external ligands by SPR spectroscopy repres ...
Innovative structured catalysts based on nanoparticles of gold supported on activated carbon fibers (ACF) in the form of woven fabrics are presented for low-temperature CO oxidation. Gold was deposited by adsorption from aqueous solution of ethylenediamine ...
A symposium report on the construction of regioselectively addressable functionalized template (RAFT) mols., e.g. I [R = Me3CO2C (Boc); R1 = H2C:CHCH2O2C (Alloc)], as conformationally stable cyclopeptide scaffolds in which lysine side chains point to oppos ...
Chem. ligation methods in combination with regioselective addressable templates have allowed the prepn. of well defined complex monomol. films tethered to gold surfaces. The supramol. monolayers exposed artificial recognition sites, here for monoclonal ant ...
