Publikováno v: Applied optics. 60(27)

A solution of spectroscopic inverse problems, implying determination of target parameters of the research object via analysis of spectra of various origins, is an overly complex task, especially in case of strong variability of the research object. O

Study of resilience of neural network solution of inverse problem based on integration of optical spectroscopic methods to noise in data

Autor: Olga Sarmanova, Tatiana A. Dolenko, Igor Isaev, Sergey A. Burikov, Sergey Dolenko, Kirill Laptinskiy

Publikováno v: Saratov Fall Meeting 2020: Laser Physics, Photonic Technologies, and Molecular Modeling.

For many methods of optical spectroscopy, there is no analytical and/or direct numerical solution for the problem of determination of concentrations of each component in multi-component solutions by spectra. Therefore, recently, the application of ma

Dependence of luminescent properties of lanthanide-based nanocomplexes on their interactions with surrounding molecules in aqueous suspensions

Autor: Tatiana A. Dolenko, Olga Sarmanova, Sergey A. Burikov, Anna A. Fedyanina

Publikováno v: Advanced Sensor Systems and Applications X.

Lanthanide-based nanocomplexes stand out among optical sensors since for them one can implement an up-conversion luminescence (UCL) mode. The property eliminates the problem of extraction of nanoprobe luminescent signal against the background of the

Cellular temperature and pH sensor based on carbon dots

Autor: Olga Sarmanova, Sergey A. Burikov, Kirill Laptinskiy, Tatiana A. Dolenko, A. E. Tomskaya, Galina N. Chugreeva, Maria Y. Khmeleva

Publikováno v: Advanced Sensor Systems and Applications X.

This study is devoted to a new approach to solve the problem of pH (in range of pH from 5 to 8) and temperature (in range of 30-45°C) measurements at nanoscale level, by using carbon dots (CDs), prepared from citric acid. These 10 nm sized nanoparti
