Abstract: Point-of-care (POC) sensor development is an emerging field in nanoscience, combining the detection abilities of standard analytical equipment with portability and affordability. These sensors often utilize engineered nano-structures, which demonstrate tuneable surface properties, high surface area to volume ratios, and pronounced reactivity compared to bulk materials. However, working with nanoscale materials introduces concerns with scaling, specifically regarding stability. The tremendous surface energy of these nano-materials often result in aggregation, a product of intermolecular attractive forces. Thus, there is a need for novel nanosensing methods, particularly those with long-term stability. In the proposed work palladium nanoparticles are incorporated into electrospun polymer nanofibers for the colorimetric detection of dopamine, a catecholamine whose physiological concentration has been linked to many medical conditions. The developed POC sensor showed good detection ability, and excellent long-term stability. The presented findings offer promising results for future development of POC sensors.
