“…Besides, excessive MWCNT content may form too thick a MWCNT layer, resulting in a smaller specific surface area of the hybrid material, thus weakening the conductivity of the electrodes. 37 Therefore, 5 mg was selected as the optimum MWCNT content.…”

“…Recently, Hou et al introduced a novel label-free impedimetric aptasensor employing dual-amplication with Naon-MWCNTs and Au nanopopcorns for highly selective and ultra-sensitive OTA detection. 23 Dridi et al reported a differential conductimetric method for OTA determination using thermolysin embedded in a bovine serum albumin matrix, successfully applied to quantify OTA in spiked olive oil samples. 24 This paper details the design of a disposable aptasensing platform for OTA using gold nanoparticles-modied screenprinted carbon electrodes.…”

“…To solve the aforementioned disadvantages, many functional materials have been introduced to the electrochemical sensor for increasing sensing performance (Gao et al, 2021; Hou et al, 2023; Kolhe et al, 2023; Shukla et al, 2020; Zhong et al, 2021). β‐cyclodextrin (β‐CD) and its derivatives have a strong selective affinity for small phenol molecules containing hydroxyl groups and are therefore often used as molecular recognition and enrichment units in the field of electrochemical sensing (Niu et al, 2018; Tu et al, 2020; Zhu et al, 2016).…”
