| 英文摘要 | in this study, a facile method to sensitively detect melamine and highly improve the peroxidase-like activity of bare gold nanoparticles (au nps) at the same time is proposed for the first time. it is interesting to find that the addition of melamine could improve the peroxidase-like activity of au nps. by coupling with 3,3',5,5'-tetramethlybenzidine (tmb)-h2o2 chormogenic reaction, a novel method for colorimetic detection of melamine is developed. the detection limit of this method is as low as 0.2 nm with the help of uv-vis spectroscopy and 0.5 mu m by naked-eye observation, both which are far below the us food and drug administration estimated melamine safety limit of 20 mu m. in addition, the present method is successfully applied for the detection of melamine in raw milk and milk powder. more importantly, the proposed method could also improve the peroxidase-like activity of au nps, which may not only provide a new approach to develop effective nanomaterials-based mimetic enzyme, but also irradiative to develop new applications for au nps in varieties of cost-effective and simple sensors in medicine, biotechnology and environmental chemistry.
