Detection method	Time/h	Advantage	Disadvantage
Reverse transcrition-polymerase chain reaction (RT-PCR)	4-6	High sensitivity and reliabilityLow costVersatility in sample types	Special instrumentsComplicated operationTime-consuming
Enzyme linked immunosorbent assay (ELISA)	1-3	Simple operationLow priceFast detection	Low specificitySuitability only for the late stage of the disease
Surface-enhancedRaman spectroscopy (SERS)	<1	Simple constructionGood repeatability	Specialized SERS active substrates
Electrochemical detection	<1	Lower costSimpler constructionHigher speciﬁcityRelatively lower sensitivity	Lower clinical trial accuracy
