Surface-enhanced Raman scattering of some Water Insoluble drugs in silver hydrosols.
Spectrochimica acta. Part A Molecular and biomolecular spectroscopy, 2003Co-Authors: Yu Wang, Zenxin ZhangAbstract:An extraction method has been used to obtain surface-enhanced Raman scattering (SERS) spectra of Water Insoluble drugs such as aspirin, salicylic acid, acetaminophen, and vitamin A acid. This method is based on the strong affinity of the sample molecules to the silver particle surfaces. Results from the present study indicate that the method can be extended to identify and analyze many other Water Insoluble compounds by SERS. The high sensitivity of SERS and the linear calibration curve make it feasible in the trace quantitative analysis; the low limit of detection is comparable or better than those of calorimetric and spectrophotometric methods.

Application of the Water-Insoluble pyrolysis oil fraction as an organic binder
Construction and Building Materials, 2016Co-Authors: Sergey Zabelkin, Andrey Grachev, Alexander Makarov, Guzeliya Fayzrakhmanova, Vladimir BashkirovAbstract:Abstract Wood fast pyrolysis oil could potentially be applied as an additive to an organic binder for use in road construction. The aim of this work was to investigate the properties of a composite binder made of bitumen and the Water-Insoluble fraction of wood pyrolysis oil. Pyrolysis oil was made from birch wood by fast ablative pyrolysis. Separation of the pyrolysis oil was conducted with recovery of the Water-Insoluble fraction of wood pyrolysis oil. A composite binder consisting of bitumen and the Water-Insoluble fraction of pyrolysis oil was produced. Modified asphalt concrete was made with the composite binder. The properties of the composite binder and the modified asphalt concrete were investigated. It can be concluded that the Water-Insoluble fraction of pyrolysis oil can be used as a component of composite bitumen binder. The best properties are exhibited by the binder supplemented with 10–15% of the Water-Insoluble fraction of pyrolysis oil.

Interface-Induced Ag Monolayer Film for Surface-Enhanced Raman Scattering Detection of Water-Insoluble Enrofloxacin
Plasmonics, 2020Co-Authors: Yuanjie Teng, Zhenni Wang, Zeyu Ren, Yanping Qin, Zaifa Pan, Kang Shao, Yuan-bin She, Weihao HuangAbstract:Water-Insoluble molecules usually show poor surface-enhanced Raman scattering (SERS) signals, because they are hardly adsorbed on the surface of most commonly used SERS substrates, such as aqueous Ag or Au colloids. In this work, a highly sensitive and reproducible Ag monolayer film (Ag MLF) SERS substrate prepared by self-assembly of Ag nanoparticles (Ag NPs) on Water/oil interface can realize the trace SERS detection of Water-Insoluble enrofloxacin. The positively charged phase transfer catalyst can transfer the negatively charged Ag nanoparticles in aqueous solution to the Water/oil interface. At the same time, the Water-Insoluble enrofloxacin can also be attracted to the interface because of its lipophilic group. The type/volume of the oil phase and phase transfer catalyst and the vortex mixing time were all optimized to maximize the SERS effect of Ag MLF. Results showed that trace Water-Insoluble enrofloxacin can be identified by Ag MLF and its detection sensitivity was significantly improved. The proposed novel Ag MLF can be further applied to detect other Water-Insoluble molecules in SERS.
