Перебудова електронної структури плівок триптофану за його взаємодії з наночастинками Ag, вкритими поліетиленгліколем.

The optical absorption spectra of layered films based on silver nanoparticles coated with polyethylene glycol (PEG) and the amino acid tryptophan deposited by thermal vacuum sputtering are studied. Quantum-chemical calculations indicate the possibility of complex formation of amino acid with polymer chains. The structure of the complexes and the electronic structure, which affects the absorption spectra and is the result of the interaction of tryptophan with PEG, are characterized. [ABSTRACT FROM AUTHOR]
