OPTICAL PROPERTIES OF CdS–Ag2S QUANTUM DOT SYSTEM
Конденсированные среды и межфазные границы, 2017 The paper presents the results of a study of systems with quantum dots of two types: CdS and Ag2S, which have different types of crystal lattices. CdS quantum dots were synthesized in the gelatin matrix by means of the sol-gel method.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin
FEBS Letters, EarlyView.The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Modification of a single-molecule AFM probe with highly defined surface functionality
Beilstein Journal of Nanotechnology, 2014 Single-molecule force spectroscopy with an atomic force microscope has been widely used to study inter- and intramolecular interactions. To obtain data consistent with single molecular events, a well-defined method is critical to limit the number of ...
