Bai et al. (2012) developed an SPR aptasensor for quickly detecting avian influenza virus (AIV) H5N1 within 1.5 h, with a detection range from 0.128 to 1.28 hemagglutination units (HAUs). Compared with other detection methods, this aptasensor was fast and portable, but the sensitivity was inferior to virus isolation and PCR methods. Traditional virus detection methods in an inactivation validation study utilize cell culture as a tool to quantify the infectious virus by observing cytopathic effects (CPEs) after virus inactivation.
