Catalysts are made of nanoparticles of metals, metal oxides, and other compounds that may act as active phases, support the latter, or a combination of both. The initial incentive to reduce as much as possible, up to the nano-scale, the size of the particles of active catalyst components is to maximize the surface area exposed to reactants, thus minimizing the specific cost per function and increasing the rate of conversion of feedstocks to products in relatively simple reactions. Nowadays, the interest in nanocatalyst developments has shifted to an emphasis on improving the selectivity of catalysts, allowing one to obtain desirable reactions in more complex synthetic processes. Thus, new generations of nanocatalysts should be designed at the molecular level to display well-defined structural characteristics, in terms of size, shapes, hierarchical porosity, and morphologies, as well as with controlled chemical composition. The development of efficient nanocatalysts supposes the characterization of their various surface active sites at the nanometer scale, which is focused on establishing synthesis-structure-performance relationships.
Описание: This thesis focuses on the study of interactions between protein and peptides and their potential applications in cell imaging and nanoparticle surface modification. Drawing inspiration from naturally occurring coiled-coil binding pairs, it proposes a novel covalent peptide tag and probe system, based on the concept of “affinity guided covalent conjugation.” This newly established methodology provides complementary resolution to protein labeling, imaging and trafficking. By systematically investigating the coordination interaction between protein and quantum dots using various engineered protein ligands, this thesis proposes a general rule for protein self-assembly on the surface of quantum dots and reports a revolutionized nanobelt protein in accordance with this rule. It is an extraordinary example of interdisciplinary research, providing answers to real-life biological problems from a chemistry perspective.
