Abstract

A new nanopolypropylene (PP) surface molecularly imprinted polyacrylamide (PP@MIP) probe was synthesized facilely for the Resonance Rayleigh Scattering (RRS) determination of trace sulfadiazine (SDZ), using PP as nanosubstrate, SDZ as template molecule, and the acrylamide as functional monomer. The catalytic effect of PP@MIP on the reduction of HAuCl4 by hydrazine hydrate to form AuNP, a nano-indicated reaction, was investigated. The generated AuNPs had a strong RRS effect, and the addition of SDZ resulted in the selective formation of PP@MIP-SDZ complex, which further promoted the generation of AuNP and increased the RRS signal. Therefore, there was developed a novel RRS assay platform for rapid, selective and sensitive detection of SDZ with a linearity range of 0.0125–0.150 nmol/L and limit of detection of 0.004 nmol/L. The recoveries were in the range of 93.3–109.9 % with the relative standard deviations (RSDs) in the range of 2.55–9.14 % in the real sample analysis.

期刊介绍: Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
