The red-edge effects: 30 years of exploration.
  • A. Demchenko
  • Physics, Medicine
  • Luminescence : the journal of biological and…
  • 2002
TLDR
Red-edge effects were discovered for electron-transfer and proton-transfer reactions if they depended on the dynamics of the environment and stimulated the emergence and development of cryogenic energy-selective and single-molecular techniques that became valuable tools in their own right in chemistry and biophysics research.

Monitoring biophysical properties of lipid membranes by environment-sensitive fluorescent probes.
TLDR
These probes are efficient for studying the microscopic analogs of viscosity, polarity, and hydration, as well as the molecular order, environment relaxation, and electrostatic potentials at the sites of their location. Expand
The Concept of λ-Ratiometry in Fluorescence Sensing and Imaging
  • A. Demchenko
  • Chemistry, Medicine
  • Journal of Fluorescence
  • 1 April 2010
TLDR
Critically analyze different approaches in λ-ratiometric sensing that use single and double fluorescence emitters and are based on different mechanisms producing spectroscopic change to explore mechanisms that allow obtaining ratiometric response from a single dye. Expand
Red-edge-excitation fluorescence spectroscopy of single-tryptophan proteins
  • A. Demchenko
  • Chemistry, Medicine
  • European Biophysics Journal
  • 2004
TLDR
Spectral shifts associated with red-edge excitation are observed for proteins emitting in the medium spectral range, suggesting the existence in these proteins of a distribution of microstates for tryptophan environment with various orientation of dipoles and of slow mobility of the field of these dipoles. Expand
Photoluminescence of carbon nanodots: dipole emission centers and electron-phonon coupling.
TLDR
It is found that photoluminescent carbon nanodots behave as electric dipoles, both in absorption and emission, and that their emission originates from the recombination of photogenerated charges on defect centers involving a strong coupling between the electronic transition and collective vibrations of the lattice structure. Expand
Fluorescent biomembrane probe for ratiometric detection of apoptosis.
TLDR
The first ratiometric fluorescent probe for apoptosis detection is developed, which incorporates selectively into the outer leaflet of the cell plasma membrane and senses the loss of the plasma membrane asymmetry occurring during the early steps of apoptosis. Expand
Recognition between flexible protein molecules: induced and assisted folding †
  • A. Demchenko
  • Chemistry, Medicine
  • Journal of molecular recognition : JMR
  • 2001
TLDR
This review focuses on a very important but little understood type of molecular recognition — the recognition between highly flexible molecular structures that is frequent in formation of different protein–protein and protein–nucleic acid complexes. Expand
Hierarchical clustering of the correlation patterns: new method of domain identification in proteins.
TLDR
HCCP allows to identify the domains using single three-dimensional structure of the studied proteins and does not require any adjustable parameters that can influence the results, which makes it an attractive method for domain identification in proteins. Expand
Excited-state proton coupled charge transfer modulated by molecular structure and media polarization.
TLDR
With knowledge of the mechanisms of these processes, desired rates and directions can be achieved, and thus the multiple emission spectral features can be harnessed. Expand
