Abstract Accurate detection of trace tetracyclines (TCs) in complex matrices is great significance for food and environmental safety monitoring. However, traditional recognition amplification tools exhibit poor specificity sensitivity. Herein, a novel dual‐machine linkage nanodevice (DMLD) proposed the first time to achieve high‐performance analysis TC, with padlock aptamer component as initiation command center, nucleic acid‐encoded multispike virus‐like Au nanoparticles (nMVANs) signal indicator, cascade walkers circuit processor. The existence spike vertices interspike nanogaps MVANs enables intense electromagnetic near‐field focusing, allowing distinct surface‐enhanced Raman scattering (SERS) activity. Moreover, through sequential activation between multistage walker catalytic circuits, DLMD system converts limited TC into massive engineering assemblies SERS probes guided by DNA amplicons, resulting synergistic enhancement bulk plasmonic hotspot entities. continuously guaranteed target progressively promoted ensure highly specific limit low 7.94 × 10 −16 g mL −1 . Furthermore, reliable recoveries real samples confirm practicability sensing platform, highlighting enormous potential intelligent nanomachines analyzing hazards environment food.

Published: July 27, 2024

The use of innumerable chemical compounds in food production to enhance agricultural quality and yield has raised significant global concerns regarding safety. To address these concerns, miniaturized solid sample preparation techniques have emerged as an appealing strategy for analyzing residues complex samples, notably those found matrices. efficacy extraction procedures hinges largely on the choice sorbent phase. Molecularly imprinted polymers (MIPs) been introduced highly selective versatile phases a wide range techniques. Their remarkable selectivity is attributed creation distinct cavities during synthesis process, which subsequently accommodate target analyte when applied. This unique characteristic empowers MIP exhibit exceptional specificity toward desired analyte. MIPs methods shown great potential increase analytical performance residue evaluation Therefore, here we present comprehensive overview current landscape employing assessment samples. Moreover, this review primarily recent reports concerning application solid-phase microextraction (SPME), in-tube SPME, by packed (MEPS), disposable pipette (DPX), tip (SPE-PT) stir bar sorptive (SBSE). Lastly, will bring some future topics analysis order new avenues enhancing products' safety assessment.
