By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanoparticles are presented in a new report. According to news reporting from Zanjan, Iran, by NewsRx journalists, research stated, "The aim of this study was to introduce a novel, simple, and highly sensitive preparation method for determination of tylosin in different milk samples. In the so-called functionalized TiO2 hollow fiber solid/liquid-phase microextraction method, the acceptor phase is functionalized TiO2 nanoparticles that are dispersed in the organic solvent and held in the pores and lumen of a porous polypropylene hollow fiber membrane."

The news correspondents obtained a quote from the research from the Zanjan University of Medical Sciences, "An effective functionalization of TiO2 nanoparticles has been done in the presence of aqueous H2O2 and a mild acidic ambient under UV irradiation. This novel extraction method showed excellent extraction efficiency and a high enrichment factor (540.2) in comparison with conventional hollow fiber liquid-phase microextraction. All the experiments were monitored at lambda(max) = 284 nm using a simple double beam UV-visible spectrophotometer. A Taguchi orthogonal array experimental design with an OA(16)(4(5)) matrix was employed to optimize the factors affecting the efficiency of hollow fiber solid/liquid-phase microextraction such as pH, stirring rate, salt addition, extraction time, and the volume of donor phase."

According to the news reporters, the research concluded: "This developed method was successfully applied for the separation and determination of tylosin in milk samples with a linear concentration range of 0.51-7000 mu g/L (r(2) = 0.991) and 0.21 mu g/L as the limit of detection."
