“…LOD may be represented diagrammatically as LOD = 3 S y / S , where S y represents the standard deviation of peak currents of the blank ( n = 3) and S represents the slope of the first analytical curve of BPA. 45,46,51 The lesser detection limit might be related to the improved charge transport and a substantially higher surface area of Cu-BTABB-MOF@rGO. These results exhibit that Cu-BTABB-MOF@rGO modified GCE is an applicable and facile platform for the detection of BPA.…”

“…Although the SELEX process is costly, after screening aptamers, their synthesis cost is significantly lower than that of antibodies. Moreover, aptamers have higher reproducibility and chemical stability, which prevents batch-to-batch variations and eliminates the need for storage at low temperatures [67,68]. Due to the inherent nature of nucleic acids, aptamers can also regain their structure after denaturation, allowing them to flexibly adapt to different assay formats that are not available with antibodies [69].…”

Aptamer-Based Lateral Flow Assays: Current Trends in Clinical Diagnostic Rapid Tests

2022

The lateral flow assay (LFA) is an extensively used paper-based platform for the rapid and on-site detection of different analytes. The method is user-friendly with no need for sophisticated operation and only includes adding sample. Generally, antibodies are employed as the biorecognition elements in the LFA. However, antibodies possess several disadvantages including poor stability, high batch-to-batch variation, long development time, high price and need for ethical approval and cold chain. Because of these limitations, aptamers screened by an in vitro process can be a good alternative to antibodies as biorecognition molecules in the LFA. In recent years, aptamer-based LFAs have been investigated for the detection of different analytes in point-of-care diagnostics. In this review, we summarize the applications of aptamer technology in LFAs in clinical diagnostic rapid tests for the detection of biomarkers, microbial analytes, hormones and antibiotics. Performance, advantages and drawbacks of the developed assays are also discussed.

“…The well‐engineered Apt as affinity receptors not only show great selectivity and specificity toward analytes but also possess good long‐term stability, and such Apt are easy to functionalize (John Ho et al., 2020). To date, numerous Apt toward food safety hazards such as bisphenol A (Hassani et al., 2020; Razavipanah et al., 2019), aflatoxin B1 (Hui et al., 2020), carbendazol (C. Zhu et al., 2019), streptomycin (L. Li et al., 2019a), malathion (Kaur et al., 2019), and acetamiprid (Yi et al., 2020) have constantly been screened and used in fabricating nanomaterial‐assisted electrochemical sensors. Peng et al.…”

Food safety as a public health issue has aroused worldwide concern. Food safety risks caused by the existence of food safety hazards in food may occur in all stages of the food supply chain. Thus, great emphasis is placed on sensitive, selective, and convenient analytical methods of various food safety hazards in food. At present, nanomaterials are at the forefront of various electrochemical sensing applications. Given their unique physical, chemical, and biological characteristics, nanomaterials are considered perfect candidates for the design of electrode surface to construct electrochemical sensors with excellent analytical performance. With the assistance of nanomaterials, electrochemical sensors are a potential alternative to conventional methods of food safety analysis. This review focuses on current research achievements of nanomaterial‐assisted electrochemical sensors for food safety analysis reported in recent 5 years. It highlights the different detection mechanisms for analytes, flexible sensing strategies based on nanomaterials, and portable miniaturized electrochemical devices. Finally, the challenges and limitations in the design of electrochemical sensors for food safety analysis are also discussed.
