DNA Locked‐in Double‐Faced‐Nanotube for Ultrafast Biosensing of Hepatitis Virus

m, advancing the available detection time as early as possible. Using human serum as a sample, this technique enables the precise and quantitative reporting of HBV-DNA within only 15 min and overcomes the interference of usual proteins and other viral DNA. This technique provides new inspiration for quick and early hepatitis diagnosis for in-hospital and non-hospital patients without bulky instruments and complex operations.
