About Novel Sensors Based on Fluorescent Polymer Brushes, PhD - at Faculty of Science, Charles University

Project summary

Polymer brushes, that is, polymer chains tethered to a surface, are exceptional structures which have attracted interest because of their great potential for the development of sensing platforms. In this project, we focus on fluorescence techniques which offer inherent nanometer scale resolution to provide essential information on polymer brush structure, conformation, density and distance between neighboring chains. Polymer brushes with fluorescent labels bound to the support, the end of the polymer chain and along the polymer chain will allow for tracing minute chemical changes in the surrounding medium based either on the properties of the fluorophore (fluorescent pH indicators, fluorophores sensitive to polarity) or by conformational changes of the brush (for instance, the response of polyelectrolytes to solution pH), which can be probed by F
