Special focus will be paid to laser-ablation techniques, and novel instrumentation and technology introduced recently.

10.  Molecular recognition in chemical analysis (non-biological aspects).

Types of interactions in molecular recognition. Non-covalent binding: molecularly imprinted polymers, host-guest complexes (crown ethers and cryptands for binding metal ions and organic species; calixarenes, cyclodextrins), charge transfer complexes, coordinatively unsaturated metal complexes. Covalent binding (boronic acids). Binding and signaling ( “two-in-one”): fluorescent sensors based on synthetic organic receptors, quantum dots, metal nanoparticles and nanoclusters. Applications of molecular recognition: molecular imaging, chiral recognition, molecular imprinting (in solid phase extraction and chromatorgaphy, quartz crystal microbalance, electrochemical sensors).

11.  Fundamental aspects, field of applications and future prospects of mass spectrometry.

Nowadays mass spectrometry is the most sensitive, informative, and reliable tool of the qualitative and quantitative analysis of any type of chemical compounds (from chemical elements to the most complex biopolymers). The method based on the measurement of the accurate mass and concentration of molecules is indispensable for the nucleus, chemical, oil industries, for the cosmic studies, biology, medicine, nanotechnology, as well as for the defense capability. The lectures will through light upon the basics of the method, including sample introduction, ionization, separation and detection of the ions. The theory will be accompanied by the examples demonstrating the unique possibilities of mass spectrometry to resolve chemical, biological, medical, ecological tasks, its application in doping-control, forensic sciences, etc.
