Optochemical and electrochemical methods for biomedical measurements, Prof. Miklόs Gratzl, 21.03.2014
Уважаемые коллеги,
в пятницу 21 марта в 15:30 в ауд. 2076 состоится доклад Miklόs Gratzl (Department of Biomedical Engineering, Case School of Engineering and School of Medicine,Case Western Reserve University,Cleveland, Ohio, USA) на тему: "Optochemical and electrochemical methods for biomedical measurements"
Аннотация:
In the first part of this talk the use of color to measure molecules of interest in colored biomedical samples will be discussed. Optode membranes translate concentrations into specific membrane colors. If the sample is also colored such as blood, optical interference from the sample itself can reduce the dynamic range of membrane colors to such an extent that no meaningful measurements are possible. Chemically connecting the sample while optically isolating its color can not only restore the original dynamic range of the measurement as in non-colored samples but further increase it. Illumination by a white light source as opposed to a LED array, and detection by a color camera relative to a greyscale camera will also be discussed.
The second part of this talk is on electrochemical measurement in biological environments where biofouling of microelectrodes can be a major problem. Differential Linear Scan Voltammetry, DLSV, can address this issue where conventional pulsed voltammetry techniques fail. In the same time, the large background currents seen with current techniques become negligible in DLSV.
