A Porous Chitosan Film-Based Dual-Modal Biosensor Integrated with Catalytic Hairpin Assembly for Sensitive Detection of Escherichia coli
Catalytic hairpin assembly (CHA), as an enzyme-free isothermal nucleic acid amplification technique, offers significant advantages in biosensing owing to its exponential signal gain. Integrating CHA with dual-modal signal output holds promise for further improving the sensitivity and reliability of pathogen detection i...
