Abstract Catalytic DNA circuits, serving as signal amplification strategies, can enable simple and accurate detection of pathogenic bacteria in complex matrices but suffer from low reaction rates depths. Herein, we design an enzyme-accelerated catalytic hairpin assembly (EACHA) which duplex products are converted into reactants to continue participating the next circuit with assistance RNase H. Profiting high recyclability reactants, EACHA exhibits approximately 37.6-fold enhancement rate constant a two-order-of-magnitude improvement sensitivity compared conventional (CHA). By integrating allosteric probe EACHA, one-pot method is developed for rapid direct S. enterica Enteritidis. This capable detecting 15 CFU mL− 1 S. Enteritidis within 20 min, superior that real-time PCR. testing 60 milk samples, demonstrate this method's accuracy discriminating contaminated area under curve (AUC) 0.997. Moreover, be employed accurately diagnose early-stage infected mice, AUC 1.00 feces samples 0.986 serum samples. Therefore, study offers feasible identifying pathogens matrices.

DNA-based nanomaterials have attracted increasing attention over the past decades due to their incomparable programmability and functionality. In particular, dendritic DNA nanostructures are ideal for constructing drug carriers highly branched structure. this study, an intelligent delivery system was constructed based on dendrimers, in which duplexes were utilized simultaneously loading both hydrophilic hydrophobic small molecule drugs. Additionally, cancer microenvironment-responsive cell-targeting moieties introduced into internal framework surface of nanostructures, respectively. Our research shows that these can enter cells through endocytosis disintegrate under reduction cellular glutathione, thereby achieving targeted co-delivery controlled release chemotherapeutic agents antisense oligonucleotides, providing effective strategy combined treatment tumors.
