Production and characterization of biocompatible nanofibrous scaffolds made of-loaded polyvinyl alcohol/tragacanth gum composites.

Electrospun polyvinyl alcohol (PVA) and tragacanth gum (TG) were used to develop nanofibrous scaffolds containing poorly water-solubleSitosterol (S). Different concentrations and ratios of the polymeric composite includingS (10% w v) in PVA (8% w v) combined with TG (0.5 and 1% w v) were prepared and electrospun.

Biocompatible biodegradable polycaprolactone/basil seed mucilage scaffold for cell culture.

In this study, a polymer obtained from the basil seed mucilage (BSM) in combination with polycaprolactone (PCL), was used in the 2D scaffold production process for cell culture. First, combinations of two polymers with different ratios and concentrations were prepared and electrospun. Among these samples, a sample with a BSM/PCL ratio of 2/3 was used to perform different tests due to its fibre uniformity and appropriate diameter.

Green synthesis of silver nanoparticles using (L.) Curtis extract and evaluation of its antibacterial activity.

The metal nanoparticles, due to interesting features such as electrical, optical, chemical and magnetic properties, have been investigated repeatedly. Also, the mentioned nanoparticles have specific uses in terms of their antibacterial activity. The biosynthesis method is more appropriate than the chemical method for producing the nanoparticles because it does not need any special facilities; it is also economically affordable.

Green synthesis of silver nanoparticles with the Arial part of extract by antimicrobial analysis.

Silver nanoparticles (SNPs) were synthesised by using the Arial part extract of . and characterised by employing UV-visible spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction techniques. Transmission electron microscopy and field emission scanning electron microscopy were applied to investigate the morphological structure of the bio-synthesised SNPs.

A ternary nanofibrous scaffold potential for central nerve system tissue engineering.

In the present research, a ternary polycaprolactone (PCL)/gelatin/fibrinogen nanofibrous scaffold for tissue engineering application was developed. Through this combination, PCL improved the scaffold mechanical properties; meanwhile, gelatin and fibrinogen provided more hydrophilicity and cell proliferation. Three types of nanofibrous scaffolds containing different fibrinogen contents were prepared and characterized.

A Paper-Based Analytical Device Based on Combination of Thin Film Microextraction and Reflection Scanometry for Sensitive Colorimetric Determination of Ni(II) in Aqueous Matrix.

In this research, the thin film microextraction method was applied for the extraction of Ni(II) ion from aqueous matrixes. Chemically modified cellulosic filter paper with phosphorus was used as a thin film extractor. After extraction, the thin film was treated with a solution of dimethylglyoxime.

Determination of Xylene and Toluene by Solid-Phase Microextraction Using Au Nanoparticles-Thiol Silane Film Coupled to Ion Mobility Spectrometry.

A simple, rapid and sensitive method for analysis of xylene and toluene was developed using the solid-phase microextraction (SPME) combined with ion mobilityspectrometry (IMS). Gold nanoparticles-thiol silane film (Au NPs-TSF) was applied as a newsorbent for SPME. Thiol silane film was formed on the surface of a stainless steel wire through incorporating Au nanoparticles during synthesis using sol-gel technique.

A novel method for the determination of three volatile organic compounds in exhaled breath by solid-phase microextraction-ion mobility spectrometry.

A method was carried out for the quantitative determination of the concentrations of volatile organic compounds (VOCs) using solid-phase microextraction and ion mobility spectrometry (SPME-IMS). This method was optimized and evaluated. The best results were obtained at sorption temperature 70 °C, desorption temperature 200 °C, and extraction time 15 min.
