An ultra-sensitive molecularly imprinted polymer (MIP) and gold nanostars (AuNS) modified voltammetric sensor for facile detection of perfluorooctance sulfonate (PFOS) in drinking water

Perfluorooctance sulfonate (PFOS) is one of the most studied Per-and-polyfluoroalkyl substances (PFAS) due to its relatively high environmental ubiquity and toxicity. This study presented an ultra-sensitive voltammetric sensor for the detection of PFOS in tap water based on a glassy carbon electrode (GCE) modified with a thin coating of gold nanostar (AuNS) and electropolymerized molecularly imprinted polymer (MIP). The AuNS coating helps to...
