Colorimetric and electrochemical dual-signal detection of uracil-DNA glycosylase using functionalized pure DNA hydrogel on paper-based analytical devices

Advanced Agrochem, Journal Year: 2023, Volume and Issue: 2(3), P. 269 - 275

Published: July 1, 2023

The development of simple and accurate detection uracil-DNA glycosylase (UDG) is great significance for early clinical diagnosis biomedical research. Here, we on the first effort introduced uracil bases into rolling circle amplification (RCA) reaction to produce functionalized pure DNA hydrogel (PDH) UDG detection. During RCA process, methylene blue (MB) molecules as indicators were encapsulated PDH. addition can remove PDH generate abasic sites, which are further cleaved with assistance apurinic/apyrimidinic endonuclease (APE), thus resulting in dissociation release MB. By combining paper analytical devices signal readout platform, a colorimetric electrochemical dual-signal biosensor was constructed convenient UDG. proposed [email protected] sensing system exhibited good selectivity high sensitivity limit 6.4 × 10−4 U/mL (electrochemical method). It also demonstrated that this showed excellent performance inhibitor screening, providing potential UDG-related disease drug discovery.
