Fluorescent Pressure Response of Protein-Nanocluster Polymer Composites

Abstract

This research focuses on the uses of polymer gold nanocluster (PNC) composites as pressure sensitive indicators of brain damage. The PNC composites are made up of protein coated gold nanoclusters and a styrene-ethylene/butylene-styrene (SEBS) mineral oil composite, invented at the US Army Research Laboratory. The PNC composites were mechanically tested using a custom made setup and an Instron frame under various pressures that match different levels of damage. The stress levels studied in this technical note are lower than those previously studied by other groups and provide a unique perspective. The data shows that fluorescence quenching is present throughout the PNC samples and can be linked to mineral oil content. This research lays the groundwork for future pressure studies and identifies a key issue when using oil inside these PNCs.
