Traditional organic planar aromatic emitters often encounter low electrochemiluminescence (ECL) efficiency due to the aggregation-induced quenching (ACQ) induced by π-π stacking, limiting their applicability in bioanalysis. In this work, we proposed a steric engineering strategy mitigate ACQ perylene diimide-bridged β-cyclodextrin aggregates (Pe-CD aggregates), significantly boosting ECL for trace microRNA (miRNA) detection. By incorporation of large volume cyclic (β-CD) at both side chains diimide, Pe-CD molecules were generated and further assembled into robust supramolecular nanoblocks. This modulates intermolecular distances around cores, effectively minimizing nonradiative relaxation. Molecular simulation results demonstrated that distance increased from 3.32 Å 5.21 Å, accompanied 5.8-fold enhancement compared Pe (formed dense stacking molecules). As proof concept, an bioassay platform was developed using as target-enrichment accelerated-3D DNAzyme walkers signal amplifiers detecting miRNA-21, achieving limit detection 9.7 aM. study offers valuable insights designing new expands potential applications technology.

In this study, an integrated dual-mode biosensor combining photoelectrochemical (PEC) and colorimetric (CL) methods was proposed to broaden the linear detection range of enrofloxacin (ENR), thus enabling sensitive ENR in aquatic products. Compared traditional PEC/CL biosensors that rely on same sensitizer for both PEC CL signals, expanded enhanced sensitivity by separating signal label CL. Specifically, platform employed a Z-type heterojunction iron indium sulfide (FeIn2S4) cadmium (CdS) significantly improve photoelectric conversion efficiency detection. Furthermore, based entropy-driven catalytic nucleic acid circuit (ETSD) strategy mediated aptamers, converted into mass output DNA. Subsequently, DNA triggered strand displacement reaction palindrome-catalyzed assembly (NEPA) form three-dimensional gold nanoparticle-DNA nanocomposite adsorption methylene blue (3D Au-DNA NC-MB). The resulting 3D NC-MB biomolecular nanocarrier then used trace with 10-5-102 ng·mL-1. Concurrently, unadsorbed MB solution high level from 10-1 104 Finally, method successfully applied detect products higher wider than most reported methods, which is anticipated use food safety environmental surveillance.
