Figures of merits of the most relevant analytical methods for HIV-1 p24 detection

	HIV-1 p24 limit of detection	Selectivity	Dynamic range	Label	Time to result
ELISA [23]	400 nM	High	4 orders of magnitude	Label-needing	Long
Nanoparticle-based bio-barcode [23]	4 nM	High	6 orders of magnitude	Label-needing	Long
Immuno-polymerase chain reaction [25]	100 fM	High	3 orders of magnitude	Label-needing	Short (few hours)
Multi-walled carbon nanotube electrochemical sensor [27]	3 fM	High	4 orders of magnitude	Label needing	Short (few hours)
SiMoT	30 zM (2±1 molecules in 100 mL)	High	2 orders of magnitude	Label-free	Short (few hours)
