Recent achievements and advances in optical and electrochemical aptasensing detection of ATP based on quantum dots

Stimulus-Responsive Metal–Organic Framework Signal-Reporting System for Photoelectrochemical and Fluorescent Dual-Mode Detection of ATP

“…As illustrated in Table S1, the proposed sensing system exhibited a good performance in terms of low detection limit, wide linear range, and simple operation. In general, the PEC sensing platforms had a lower detection limit than the FL sensing platforms, with the detection limits in the nanomolar and picomolar ranges . For this sensing system, the detection limit of PEC and FL analysis were within the picomolar range, and the operation was simple without the involvement of the enzyme and aptamer.…”

“…In general, the PEC sensing platforms had a lower detection limit than the FL sensing platforms, with the detection limits in the nanomolar and picomolar ranges. 16 For this sensing system, the detection limit of PEC and FL analysis were within the picomolar range, and the operation was simple without the involvement of the enzyme and aptamer. The high performance may be attributed to the signal amplification effect of sufficient MV load in ZIF-90 and the rapid response of MV@ZIF-90 to ATP.…”

“…Therefore, ATP has been recognized as a powerful indicator for clinical diagnosis and disease treatment evaluation. , In addition, ATP can also be used to indicate the degree of microbial contamination in the food industry, which makes ATP content detection also valuable in food safety and biochemical research. , So far, considerable efforts have been made to develop ATP detection technologies through fluorescence (FL), colorimetry, electrochemiluminescence, electrochemistry, and photoelectrochemical (PEC) methods . Among them, PEC analysis shows unique advantages due to its superior analytical performance (high sensitivity) and desirable potential in the point-of-care diagnosis and field testing (portable, responsive, and cheap). − Through literature research, the currently reported PEC strategies for ATP detection basically required the participation of an ATP aptamer and enzyme, which put forward high requirements for experimental operation and conditions. , Moreover, the developed PEC biosensors were based on a single signal readout mode that is vulnerable to variable coexisting interferents, altered handling personnel, or nonstandard instruments and procedures.…”

Advances in electrochemiluminescence for single-cell analysis

“…63 With advances in the preparation of high-performance nanomaterials, various semiconductors are characterized for highly efficient ECL nanoprobes. 64 For example, metal QDs, 65,66 carbon dots (CDs), [67][68][69] and metal nanoclusters (NCs) [70][71][72] are widely used in ECL research.…”

Advances in chilling injury of postharvest fruit and vegetable: Extracellular ATP aspects

“…Due to these unique features, aptamer‐assisted techniques, such as fluorescent, colorimetrical, and electrochemical sensors, have been applied to monitor eATP dynamics (He et al., 2013; Sang et al., 2019; Zhou et al., 2010). Furthermore, strong binding to ATP with a long conservation life, high biocompatibility, low denaturation sensitivity, marker versatility, and ease of modification was developed (Khojastehnezhad et al., 2021). Recently, gold nanoparticle (AuNPs) materials have gained more attention in colorimetric biosensors due to the ultrahigh extinction coefficient of the surface plasmon resonance absorption (Huo et al., 2016; Li et al., 2014b).…”
