Abstract
Affinity characteristics of biomolecules, such as peptides and proteins, towards inorganic surfaces in general and to titanium oxide in particular become crucial in biotechnology and bionanotechnology. Amino acids are often used as “model” bits of peptides or proteins for studying their properties in different environments, and/or developing functional surfaces. Despite the great demand for knowledge about amino acid interactions with metal oxide surface, studies on the issue lack in consistency and represent a fragmentary picture. This paper is an attempt to study amino acid adsorption on nanocrystalline anatase systematically at uniform conditions. Features of the L- alanine adsorption have been revealed and interpreted with quantum-chemical calculations.
