Nanotechnology in analytical chemistry

Head of the Division: Prof. Karel Lemr, Ph.D.

Scientific focus of the division:

• research, description and modeling of analytical processes when passing to the nanoworld (ionization of compounds, nanoseparation bed, effect of nanoparticles on interaction of radiation with an analyte, electrochemical transformations, etc.);
• new analytical devices (ion sources, separation systems, sensitive detection systems, etc.) and novel analytical methods (lower detection limits, faster analysss, new application possibilities, cheaper analyses, etc.);
• characterization of nanomaterials, investigation of relations between followed parameters and behavior of nanomaterials;
• the analysis of various samples, e.g. minerals, environment, biological samples, surface analysis;
• development of methods for monitoring of transformations of toxic or pharmacologically active substances, interaction of the substances with living organisms (metabolism, bond to proteins);
