Herein, an efficient and feasible photoelectrochemical (PEC) biosensor based on gold nanoparticle-decorated graphitic-like carbon nitride (Au NPs@g-C 3 N 4 ) with excellent photoelectric performance was designed for the highly sensitive detection of mercury ions (Hg 2+ ) . The proposed Au NPs@g-C 3 N 4 was first modified on the surface of the electrode, which possessed a remarkable photocurrent conversion efficiency and could produce a strong initial photocurrent. Then, the thymine-rich DNA (S1) was immobilized on the surface of the modified electrode via Au–N bonds. Subsequently, 1-hexanethiol (HT) was added to the resultant electrode to block nonspecific binding sites. Finally, the target Hg 2+ was incubated on the surface of the modified glassy carbon electrode (GCE). In the presence of target Hg 2+ , the thymine–Hg 2+ –thymine (T-Hg 2+ -T) structure formed due to the selective capture capability of thymine base pairs toward Hg 2+ , resulting in the significantly decrease of the photocurrent. Thereafter, the proposed PEC biosensor was successfully used for sensitive Hg 2+ detection, as it possessed a wide linear range from 1 pM to 1000 nM with a low detection limit of 0.33 pM. Importantly, this study demonstrates a new method of detecting Hg 2+ and provides a promising platform for the detection of other heavy metal ions of interest.

“…Recently electrochemistry-based light-emitting systems have gained considerable attention due to the possible direct visualization of chemical information. Different light-emitting systems, based 3 on electroluminescence [10][11][12][13][14] or fluorescence [15] have been exploited for the quantification of different analytes of interest [16][17][18][19][20]. However, these methods require the use of additional chemicals, such as luminophores, co-reactants, fluorescent dyes, and often the light emission is triggered by complex reactions pathways.…”

“…18 Recently, Li et al reported that a cyclic peptide with a cyclo[-CNDNHCRDNDC-] sequence can be used as a molecular recognition element for glucose sensing. 19 After that, a colorimetric method 20 and an ECL method 21 were developed for the detection of glucose using CP as the molecular recognition element. The ECL method for the determination of serum glucose was based on the employment of CP as a molecular recognition element and gold nanoparticles (AuNPs)/g-C 3 N 4 as an ECL emitter.…”
