Organophosphorus pesticides (OPs) can inhibit the activity of acetylcholinesterase (AChE) to induce neurological diseases. It is significant exploit a rapid and sensitive strategy monitor OPs. Here, metal–organic framework (MOF) acted as carrier encapsulate AuNCs, which limit molecular motion trigger aggregation-induced emission (AIE) effect, exhibit strong fluorescence with lifetime quantum yield 6.83 μs 4.63%, respectively. Then, marriage colorimetric signals was realized on basis dual...
Microcystins, the lethal cyanotoxins from Microcystis aeruginosa, can inhibit activity of protein phosphatase and promote liver tumors. Herein, a dual-modal split-type immunosensor was constructed to detect microcystin-LR (MC-LR), based on photocurrent change CdS/ZnO hollow nanorod arrays (HNRs) blue shift surface plasmon resonance peak Au nanobipyramids@Ag. By using mesoporous silica nanospheres as carrier immobilize secondary antibody DNA primer, hybridization chain reaction adopted...
Abstract Immunosensor with photoelectrochemistry and fluorescence responsibility is widely used in biomedical detection, health monitoring, food safety inspection. The cumbersome configuration low integration of the current immunosensors, however, have brought challenges for their practical applications. To address these challenges, a portable phone‐APP controlled dual‐modular immunosensor based on bimetallic metal–organic framework (MOF) heterostructured photoelectrode, ZnO/NiZn‐MOF/CdS,...
Post-transcriptional regulators, microRNAs (miRNAs), are involved in the occurrence and progression of various diseases. However, due to complexity disease-related miRNA regulatory networks, typing identification miRNAs have remained challenging. Herein, a linear ladder-like DNA nanoarchitecture (LDN) was constructed promote movement efficiency tripedal walker (T-walker), which combined with DNA-based logic gates PTCDA@PDA/CdS/WO3 photoelectrode develop novel biosensor for detection...
Abstract Current research on single‐atom nanozymes has predominantly concentrated 2D structures, with limited exploration into the influence of 3D biomimetic structures their catalytic performance. In this work, a nanostructure Pt nanozyme (Pt‐NC SAzyme) is fabricated by encapsulating platinum 2,4‐pentanedionate in each molecular cage ZIF‐8 and then pyrolyzing. X‐ray absorption fine structure analysis confirmed presence as single atoms, atom exclusively coordinated four nitrogen while *O...
The abnormal expression of microRNA (miRNA) can affect the RNA transcription and protein translation, leading to tumor progression metastasis. Currently, accurate detection aberrant miRNA, particularly using a portable system, remains great challenge. Herein, novel dual-mode biosensor with high sensitivity robustness for miR-21 was developed based on cis-cleavage trans-cleavage activities Cas12a. miRNA be combined hairpin DNA-horseradish peroxidase anchored CdS/g-C3N4/B-TiO2 photoelectrode,...
Point-of-care testing (POCT), with its portability and high sensitivity, is an analytical device for rapid on-site sensing detection. In this study, a POCT was designed the portable detection of illegal additives by integrating coil that can visually sense color distance two-electrode electrochemical system. Real-time monitoring pressure changes achieved driving CeO2@Pt/Au nanoparticle (NP)-labeled antibodies into competitive immunoreaction, in which CeO2 Pt/Au synergistically catalyzed...
Abstract Nanozymes are conceived to replace natural enzymes avoid expensive processing techniques and fragile reservation conditions. Unfortunately, the self‐limited reaction has run counter desire for sustainable catalysis as enzymes. Herein, universal mechanism overcome self‐limitation of nanozymes caused by absorption ions on active sites is explored. Therefore, dual noble metals (Au/Pt) introduced center synthesize two kinds with different types central metal elements (Cu Ce) also...

Natural protein‐protein communications, such as those between transcription factors (TFs) and RNA polymerases/ribosomes, underpin cell‐free biosensing systems operating on the transcription/translation (TXTL) paradigm. However, their deployment in field analysis is hampered by delayed response (hour‐level) complex composition of vitro TXTL systems. For this purpose, we present a de novo‐designed ligand‐responsive artificial communication (LIRAC) redefining connection TFs non‐interacting...
