A novel sensor for highly selective and sensitive detection of CN via its promising photo-induced electron transfer (PET) feature. This sensor displayed dual-channel response to CN in EtOH/H2O (7:3, v/v) HEPES solution, and have strong anti-interference toward other common anions. The sensor was successfully applied to detect CN in food samples. The test strips could conveniently and rapidly (within a short time of 3 s) detect CN in aqueous medium.
