摘要:
Herein we describe the development of cyclam-coated gold nanoparticles (cyclam-Au NPs) based sensitive colorimetric method for neomycin and gentamicin detection. The cyclam-Au NPs were characterised by UV-vis spectroscopy, fourier transform infrared spectroscopy, transmission electron microscopy techniques, dynamic light scattering and zeta potential measurements. The cyclam-Au NPs aggregated in presence of neomycin and gentamicin, which results a colour change from violet to blue. The characteristic absorption peak at 530nm was bathochromic-shifted to a longer wavelength (660nm). This confirms the aggregation of cyclam-Au NPs in the presence of neomycin as well as gentamicin via hydrogen bonding. The UV-vis absorption measurements employed to determine detection limit of neomycin and gentamicin. The detection limit is 1.87x10(-8)M and 2.35x10(-8)M for neomycin and gentamicin respectively.
