Abstract The accurate and highly sensitive detection of the tumor marker CYFRA21-1 is crucial for screening diagnosing potential lung cancer patients with non-small cell (NSCLC). A sandwich-type photoelectrochemical (PEC) immunosensor based on a ZnO/poly(5-formylindole) (P5FIn)/anthocyanin heterostructure was developed to achieve background-free CYFRA21-1. ZnO good photovoltaic properties combined narrow bandgap P5FIn form p-n type heterojunction. This structure reduces recombination efficiency electron-hole pairs, thereby enhancing photocurrent response composite. Anthocyanidins are environmentally friendly natural compounds excellent antioxidant, redox properties, remarkable electrochemical activity. After sensitization by anthocyanins, absorption utilization visible light in composites enhanced, further improving PEC luminescence materials. Additionally, boron nitride quantum dots (BN QDs) Ab2 via polydopamine (PDA) as secondary antibody marker, its sensitivity. sensor exhibited linear range (LDR) 0.001-100 ng mL− 1 limit (LOD) 0.00033 1. Furthermore, this demonstrates selectivity, reproducibility, stability, well successful results detecting actual human serum samples. approach provides feasible method detection.

Abstract Electrochemical technology provides unique opportunities to create an environment‐friendly and sustainable chemical industry. Nano‐electrochemistry offers valuable insights into the comprehension of electrochemical mechanisms behaviors at nanoscale, as opposed complex ensemble systems. Despite use various analytical tools, such nanopore scanning probe microscopy, for nano‐electrochemical research, direct operando high‐throughput spatially resolved measurements remain challenging. Electrochemiluminescence (ECL) is reactions‐dependent luminescence process without external light sources. Coupled with a microscopy configuration, novel imaging methodology ECL (ECLM), developed. ECLM, due its distinctive mode, holds considerable potential in field nano‐electrochemistry. This review will initially present overview basic principles ECL. The next section describe design ECLM apparatus discuss diverse applications Finally, challenges outline prospects further development technique summarized.

A designed "on-off-on" signal-switchable electrochemiluminescence (ECL) aptasensor based on a donor-acceptor (D-A) conjugated covalent triazine framework (CTF) has been constructed for the sensitive and accurate detection of aflatoxin B1 (AFB1) with assistance nicking endonuclease (Nb.BbvCI)-powered DNA walking machine. The D-A CTF, generated from reaction between 2,4,6-tris(4-formylphenyl)-1,3,5-triazine (TFPT) tris(4-aminophenyl)methane (TAPM) (denoted as TFPT-TAPM-CTF), simultaneously serves superior ECL emitter platform anchoring bioprobe. high response TFPT-TAPM-CTF can be quenched by anchored Cy5-labeled single-strand (Cy5-ssDNA) via resonance energy transfer. Furthermore, immobilization double-strand AFB1-targeting aptamer walker (Hp) reduces TFPT-TAPM-CTF. When detecting AFB1, separates to capture specific targets, resulting in hybridization free Hp strand Cy5-ssDNA. With Nb.BbvCI, released partial Cy5-ssDNA helps recover some extent, further liberating autonomously bind another trigger new cleavage process. In addition its selectivity promising practicality, shows an ultralow limit 0.59 pg·mL-1 within wide range 1.0 5.0 × 104 pg·mL-1. This work broadens application CTF food safety field provides aptasensing strategy precise inspection mycotoxins products.
