Conductive polymer-based electrochemical aptasensor for sensitive detection of cylindrospermopsin in water resources
Abstract
(0.58 ± 0.022 nM) in lake water, respectively, using EIS. Conductive polymer modifications, with PEDOT and PPy, significantly enhanced the analytical response. Both platforms exhibited high selectivity toward CYN over other environmentally relevant cyanobacterial toxins, including okadaic acid (OA), saxitoxin (STX), and anatoxin-a (ATX-a), which are known to co-occur with CYN in freshwater blooms. In addition, the developed aptasensors retained their functional performance over a 7-day storage period, indicating suitable stability for practical use. This practical approach for the early detection of CYN in aquatic environments contributes to the prevention of water-related health risks and supports sustainable agricultural practices.
