The electrochemical detection of BPA often requires modification of electrodes to overcome BPA′s slower kinetics and higher oxidation potential. This work reports a modification‐free, paper electrode based on vacuum‐filtered SWCNT thin film. The prepared electrode does not need to be polished or transferred into the conducting substrates. The linear sweep voltammetric detection showed a linear response from 0.5–10 μM and 25–100 μM with the experimental LOD of 1.0 μM (S/N=3). The interference study and good recovery percentage (93–105 %) in real water samples demonstrated the method's selectivity. The sensor can be promising for developing a simple, low‐cost, portable, and paper‐based BPA monitoring system. [ABSTRACT FROM AUTHOR]
