Silicon nanowires for 'turn-on' fluorescence detection of Zn(II)
چکیده انگلیسی
The surface of the silicon nanowire was covalently modified with silane derivative of acenaphthene to form a 'turn-on' fluorescence sensor for Zn(II). The fluorescent intensities of the sensor were linearly increased with the increment of the Zn(II) concentration in the range of 0.0-20 μM, and a good selectivity and sensitivity to Zn(II) were obtained. Differently from conventional Zn(II) ion fluorescence sensor, the present sensor could be repeatedly used and exhibit a facilitation in practical application.
