研究目的
Investigating the enhancement of electrochemiluminescent biosensor sensitivity for uracil DNA glycosylase (UDG) assay through host-guest recognition coupled with triple signal amplification.
研究成果
The host-guest recognition coupled with triple signal amplification significantly enhances the sensitivity of the ECL biosensor for UDG assay. The biosensor demonstrates high selectivity, stability, and reproducibility, making it suitable for screening UDG inhibitors and measuring cellular UDG activity.
研究不足
The study does not address potential interference from complex biological matrices in real-world applications, and the long-term stability of the biosensor under various conditions was not extensively explored.
1：Experimental Design and Method Selection:
The study involves the design of an ECL biosensor that utilizes host-guest recognition between β-cyclodextrin (β-CD) and ferrocene (Fc) for signal amplification.
2：Sample Selection and Data Sources:
UDG samples of varying concentrations were used to test the biosensor's sensitivity.
3：List of Experimental Equipment and Materials:
The biosensor was constructed using FeMOF/AuNPs@luminol as a platform, with prussian blue and Fc for signal amplification.
4：Experimental Procedures and Operational Workflow:
The biosensor's performance was evaluated through ECL signal measurement in response to UDG concentration, with optimization of conditions.
5：Data Analysis Methods:
The ECL intensity was correlated with UDG concentration, and the biosensor's selectivity and stability were assessed.
