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.

Over the past two decades, iron-based metal-organic frameworks (Fe-MOFs) have attracted significant research interest in biomedicine due to their low toxicity, tunable degradability, substantial drug loading capacity, versatile structures, and multimodal functionalities. Despite great potential, transition of Fe-MOFs-based composites from laboratory clinical products remains challenging. This review evaluates key properties that distinguish Fe-MOFs other MOFs highlights recent advances synthesis routes, surface engineering, shaping technologies. In particular, it focuses on applications biosensing, antimicrobial, anticancer therapies. addition, emphasizes need develop scalable, environmentally friendly, cost-effective production methods for additional meet specific requirements various biomedical applications. ability combine therapies, hurdles still remain, including a deeper understanding therapeutic mechanisms potential risks resistance overdose. Systematically addressing these challenges could significantly enhance prospects potentially facilitate integration into mainstream practice.

In this study, we present an intelligent electromagnetic-actuated microfluidic chip integrated with a G-quadruplex DNAzyme-based biocatalysis platform for rapid and sensitive tetracycline (TC) detection. sensing system, TC significantly quenches fluorescent magnetic carbon dots (M-CDs) via the internal filtration effect dynamic quenching (the excitation emission wavelength at 350 440 nm, respectively). Then, on M-CDs-Aptamer is exposed bound hemin to form hemin-G-quadruplex DNAzyme, catalyzing conversion of 3,3',5,5'-tetramethylbenzidine produce blue color. This enables fluorescence/colorimetric detection TC. Importantly, automatic electromagnet-integrated was designed control shuttling materials in each function slot according programmed sequence. Under optimal conditions, limits fluorescence colorimetric methods were 11 43 μmol/L, respectively. The results tilapia (Oreochromis nilotica) comparable those traditional high-performance liquid chromatography. offers excellent performance determination potential portable, trace pollutants food environment.
