Abstract：
The modern monolithic porous polymers emerged 25 years ago. While the early polymer-based monoliths were used almost entirely for the rapid separations of proteins and other large molecules, current literature describes a number of different applications in addition to typical liquid chromatography thus demonstrating versatility of the monoliths. For example, new approaches and functionalization methods leading to desired chemistries are being continuously developed to produce monolithic columns for the separation in various chromatographic modes. Out of these, attachment of metal organic frameworks (MOF) and nanoparticles on the internal pore surface is a very handy tool. The use of nanoparticles extends applications of monoliths in the field of highly selective fishing-out systems, permits reversible functionalization via attachment of functional thiols, and provides surfaces for highly sensitive surface enhanced Raman spectroscopy (SERS). Modification of pore surface with nanostructures such as MOF enables applications of monoliths in the area of highly selective absorbing systems. Thin monolithic layers are gaining more attention as well, since they enable efficient separations of proteins using very simple means and facilitate mass spectrometry or SERS detection. Monoliths also serve as supports for immobilization of enzymes to form very active enzymatic reactors. Several these approaches and applications will be presented.
Biography:
Professor Frantisek Svec received his Ph.D. degree in polymer chemistry from the Institute of Chemical Technology, Prague (Czech Republic) in 1969. He was the Facility Director and Chief Scientist in the Molecular Foundry of the Lawrence Berkeley National Laboratoryfrom 2005 to 2014. His main scientific interest focuses on the combination of polymer and ****ytical chemistry, including preparation of novel porous polymer materials used for separations in liquid and gas phases, as supports for immobilization of biological catalyst, as well as for gas adsorption, separation and storage; development of monolithic polymers with unprecedentedly large surface area using hyper-crosslinking reaction; development of nanostructured-polymer composites. Currently, he is part-time PI in BAIC-SM.
