The color of squaraine solution shows a "fingerprint" change upon addition of different surfactants. A cross-responsive sensing array based on a small molecular probe was applied to discriminate surfactants with 100% confidence limits. Furthermore, the probe can selectively detect sodium dodecyl sulfate (SDS) with turn-on fluorescence response.
