Nanochips exhibited detection limits of 1 pM in aqueous solution and 0.1 ppm in gaseous state against 4-nitrophenol. Vapor phase sensing of 4-nitrotoluene, 1-nitronaphthalene and 5-nitroisoquinoline using the developed 4-nitrophenol-imprinted plasmonic nanochips demonstrated partially selective response with time to signal saturation starting from 2 minutes.
