Organic Semiconductors in Chemical Analysis
Intensive course for students and others will be held at the Department of Analytical Chemistry in November 18th to 29th, 2013. Design of new materials for chemical analysis is just as important as development of new methods. In the series of six lectures the use of organic semiconductors (OS) in electrochemical sensors will be reviewed. The lectures will be presented by Dr. Mira Josowicz and Dr. Jiri Janata both from Georgia Institute of Technology, Atlanta, USA.
The lectures are independent of each other but preferred sequence is given below. The lectures will be presented by Dr. Mira Josowicz (M) or Dr. Jiri Janata (J).
- “Polyaniline-metal composites. Part I Top-down approach” (M) in the Library Room117 of the Department on Monday 18th at 9:00 a.m. Composites of polyaniline and metals is a new class of materials for chemical analysis. Its use in chemical sensors will be described.
- “Polyaniline-metal composites. Part II Bottom-up approach” (M) in the Lecture Hall CH2 on Tuesday 19th at 14:00. Polyaniline is used as an isolation matrix for preparation of atomic clusters “one-atom-at-the-time”. Clusters of AuN-PdM with N and M 1-7 atoms have been prepared. They show remarkable catalytic properties.
- “Charge transfer doping of organic semiconductors in gas phase potentiometry” (J) in the Library Room117 of the Department on Wednesday 20th at 9:00 a.m. When a dry OS is exposed to a gas or a vapor that can donate or accept electrons charge transfer complex is formed. Such interaction results in reversible modulation of work function (WF) of the OS which is measured.
- “Probing Hybridization with Label- and Marker-free Voltammetric DNA Detector” (M) in the Library Room 117 of the Department on Monday 25th at 9:00 a.m. Effect of partial blockage of ion exchange during voltammetric experiment due to the hybridization of probe and complementary target DNA molecule is the basic transduction principle of this technique.
- “Equilibrium fluctuation analysis of OS doping” (J) in the Lecture Hall CH2 on Tuesday 26th at 14:00 Spectral analysis of noise, otherwise known as “equilibrium noise analysis” yields information that is equivalent to that obtained from e.g. impedance spectroscopy.
- “Integrated multisensing electrochemical arrays” (J) in the Library Room117 of the Department on Wednesday 27th at 9:00 a.m. Pitfalls and promises of fabrication of multisensing arrays will be discussed.
In addition to this series a separate lecture on “Největší objev” (sometime first week in lecture hall CH1) will be presented in Czech at popular science level (J). It deals with current controversy surrounding discovery and use of nuclear fission.
