In-situ growth of SnO2 nanoparticles on Nb2CTx nanosheets as highly sensitive electrochemical sensing platform for organophosphorus pesticide detection

Recent advances using MXenes in biomedical applications

“…Table 1 lists electrochemical MXene-based sensors for small molecules published in 2023. MXene (especially Ti 3 C 2 ) and other conductive nanomaterials (typically gold nanoparticles) have been used for the sensing of hydrogen peroxide, [112][113][114] Aflatoxin B1, [115][116][117] chlorpyrifos, [118][119][120] and glucose [121][122][123][124] with sensing ranges in nM to mM and limits of detection in pM to mM ranges. A specific receptor for the detection of some small molecules is not always required; often their characteristic redox potentials are sufficient.…”

A new plant-esterase inhibition based electrochemical sensor with signal amplification by MoS2@N-CDs for chlorpyrifos detection

“…Among them, electrochemical biosensing techniques utilizing the inhibitory effect of CPF on acetylcholinesterase (AChE) activity have emerged as an important tool for trace CPF residual detection. 11,12 Tun et al 13 prepared an AChE-based electrochemical sensor modied with cellulose nanobers and graphene oxide to implement highly sensitive CPF detection based on the inhibition of CPF on AChE activity. Suwannachat et al 14 constructed an electrochemical biosensor based on AChE and utilized CuNWs and rGO to modify the screen-printed electrode for highly sensitive detection of chlorpyrifos.…”
