DNAzyme-based biosensors have emerged as a promising tool for ensuring food safety due to their high sensitivity, specificity, and potential rapid, cost-effective detection of hazardous substances. These leverage DNAzymes-catalytically active DNA molecules-to detect range contaminants, including metal ions, fungal toxins, pesticides, pathogens. While show significant advantages over conventional techniques, challenges such nuclease degradation, interference from complex sample matrices, the costs associated with DNAzyme synthesis still hinder widespread application. Recent advancements in stability DNAzymes, immobilization strategies, integration nanomaterials are progressively addressing these limitations, enhancing performance reliability sensors. This review highlights structural catalytic characteristics assesses current applications safety, discusses innovative strategies overcome existing challenges. The continuous evolution biosensors, particularly design device integration, holds great promise future role routine, reliable analysis.

Within gold nanoparticles screen-printed carbon electrode (AuNPs-SPCE) by electrodeposition, deposition potential EDEP, time tDEP, concentration HAuCl4 were optimized their influence was monitored on 1 mM [Ru(NH3)6]3+/2+ redox probe 50 μM DOP. morphology AuNPs-SPCE prepared at various modification conditions observed SEM. performance different evaluated a construction calibration curves DOP PAR. SPCE condition providing best sensitivity to PAR DOP, successfully used determine in tap water "spike-recovery" approach. BES yields better reproducibility (RSD = 3.0%) comparison with case when manually highly skilled laboratory operator 7.0%).
