摘要

Based on the colorimetric analysis of gold nanoparticles and a smartphone readable strategy, a stable, sensitive, and visual method was established for rapid detection of acetamiprid residues in agricultural products. By optimizing the key parameters, the detection process only took 40 minutes with good specificity. The acetamiprid aptamer can help AuNPs to resist salt-induced aggregation. Conversely, in the presence of acetamiprid, the anti-protection is weakened and the AuNPs aggregated with the color change of the solution. The photographs of the solution are recorded by the smartphone and analyzed through image processing. In the range from 25 to 300 μM the method can realize a quantitative analysis of acetamiprid, and the detection limit is about 3.81 μM. Excellent recoveries are taken in samples of cucumber, cabbage, and river water, ranging from 96.78% to 129.95%. These results show no significant difference from the results obtained by the microplate reader. What's more, the method employs a smartphone to read without the assistance of professional equipment, which greatly reduces the cost of detection, and shows a promising application prospect for on-site rapid detection of acetamiprid.

Chemistry fascinates us. This discipline is integral to life and impacts so many aspects of our world. The scope for RSC Advances is wide-ranging because we want to capture any research that can offer crucial insights and advance chemistry. RSC Advances papers should provide an insight that advances the chemistry field. Papers that contain little or no chemistry and are not considered to be of interest or relevance to the chemistry community are not within the scope of the journal. The criteria for publication are that the work must be high quality, well conducted and advance the development of the field. Articles submitted to the journal are evaluated by our international team of associate editors and reviewers for the overall quality and accuracy of the science presented. Download our full list of subject categories to see the range of topics we publish in RSC Advances. Please ensure you have considered the following points before submitting your manuscript. Does the work present an advance over the existing literature? Please supply a covering letter with your submission to demonstrate how the work is advancing the field over the existing literature Have you provided sufficient evidence/data to support your conclusions? Have you provided adequate characterisation data for your materials/compounds? (Please check the supporting information section to ensure that the necessary requirements have been met and copies of relevant spectra have been provided where necessary) Are the results discussed in the context of the literature? Are the references relevant and do they appropriately reflect the existing literature?
