The increased demand for consuming seafood has made production undergo a rapid period of growth. However, high risk contamination from harmful microorganisms and marine toxins which can cause health problems humans it. Concerning this issue, monitoring safety become center attention researchers, developing effective methods detecting in critical research field. In context, biosensors have served as promising approach to monitor contamination. Compared conventional methods, some key benefits such sensitivity, selectivity, portability, user-friendly operation. Along with significant advances biosensors, processes be simplified performed outside the laboratory. review article, we describe mechanisms two main types regarding electrochemical optical biosensors. current reports within last five years on application these are also summarized.

This work reported gold nanoparticles (AuNPs)-based colorimetric immunoassay with the Cu-based metal–organic framework (MOF) to load pyrroloquinoline quinone (PQQ) for catalytic oxidation of cysteine. In this method, both Cu2+ and PQQ in MOF could promote inducer cysteine by redox cycling, thus limiting cysteine-induced aggregation AuNPs achieving dual signal amplification. Specifically, recombinant carcinoembryonic antigen (CEA) targets were anchored on through metal coordination interactions between hexahistidine (His6) tag CEA unsaturated sites MOF.

Note that most proteins commercial kits are His6 N- or C-terminal, so provide sensitive platform biomarkers.

In recent years, entropy-driven circuit (EDC) dynamic DNA networks have garnered significant attention in nucleic acid detection owing to their simplicity, efficiency, and flexible design. Nevertheless, conventional EDC reactions face a constraint achieving optimal signal amplification due solitary feeble driving force. To overcome this limitation, we innovatively devised gold nanoparticle (AuNP) dispersion-enhanced (Au-EDC) approach, pioneering novel colorimetric output system. The system was harmoniously integrated with the ligase chain reaction (LCR) for precise single nucleotide polymorphism (SNP) genotyping. Specifically, LCR selectively executed solely on positive strand of mutant target (MT), facilitating point-to-strand information transduction. Subsequently, product triggered Au-EDC cycling reaction, causing DNA-AuNPs network progressively disintegrate release pronounced signal. This strategic design ingeniously harnessed entropy increase that occurs as AuNPs undergo transition from aggregated dispersed states, offering supplemental impetus cycle. LCR-Au-EDC excelled detecting MT at concentrations low 320 fM differentiating pooled samples mutation frequencies 0.1%. Moreover, accurately performed SNP genotyping real genomes derived soybean leaves. Consequently, study not only develops sensing based but also provides cost-effective efficient tool.
