Liquid flow sensing experiments with Tiiii@SWCNT-based devices at pH 5. a) Tiiii@SWCNT and pristine SWCNTs show opposite responses upon exposure to a 1 mM solution of 4 b) Comparison of the current change upon exposure of Tiiii@SWCNT and pristine SWCNTs devices to 4 (sarcosine ethylester hydrochloride), 5 (glycine ethylester hydrochloride) and 6 (tetraethylammonium chloride), error bars are based on three consecutive measurements c) Response of Tiiii@SWCNT devices to different concentrations of 4, error bars are based on three consecutive measurements d) Response of Tiiii@SWCNT devices to alternating exposure to 4 and 5
