Polystyrene Nanoplastic‐Mercury Complexes Detection by Electrolyte‐Gated Carbon Nanotube Field‐Effect Transistor‐Based Sensors

Advanced Materials Interfaces, EarlyView.
An electrolyte‐gated field effect transistor sensor is used to detect an environmentally relevant nanoplastic model. The sensor identifies the presence of polystyrene nanoplastics in water dispersions without significantly altering its performance in the presence of mercury on the nanoplastics’ surface, indicating that it may be utilized in ...
