“…The diffraction peak occurring at 2θ angle of approximately 16.82° was ascribed to the PAN fibers. In addition, the three new characteristic diffraction peaks at 29.21°, 31.72°, and 47.98° were associated with the hexagonal phase of covellite structure . The 2θ locations of these three diffraction peaks were consistent with the Joint Committee on Powder Diffraction Standards (JCPDS) file No.…”

In this study, antibacterial and electrically conductive polyacrylonitrile (PAN) fibers were prepared by one‐step reaction between Cu2+ and S2– ions without extra reducing agents. The copper sulfide layer was firmly adhered to PAN fibers with the help of nitrile groups from PAN fibers and chelating agent of ethylenediaminetetraacetic acid disodium salt. The copper sulfide layer was characterized by scanning electron microscopy, transmission electron microscopy, energy‐dispersive spectrometry, X‐ray diffraction, Raman and X‐ray photoelectron spectroscopy. The results illustrated that a compact and uniform copper sulfide layer was coated on PAN fibers with 108 nm thickness, and it was proved to be a pure hexagonal phase of covellite structure. The average resistance of the resultant fibers was about 360 Ω/cm and the mass content of copper sulfide was about 13.3%. The antibacterial tests demonstrated that the resultant fibers exhibited excellent antibacterial properties with antibacterial efficiency of 99.99% against Staphylococcus aureus and 96.80% against Escherichia coli. Furthermore, the antibacterial activities and electrical conductivity still remain good after 30 cycles of standard washing, indicating their good durability when in use. © 2017 Wiley Periodicals, Inc.

“…Most of the procedures include hydrothermal processes and their variations, which can provide an easy and efficient way to produce good quality, uniform nanostructures with high aspect ratios (Figure d) . Meanwhile, thermolytic degradation of copper thiolate precursor without solvent, the use of a paired cell at room temperature, and amylose‐directed synthesis, have also been investigated for the preparation of these CuS nanostructures.…”

Copper sulfide (CuS) nanoparticles have attracted increasing attention from biomedical researchers across the globe, because of their intriguing properties which have been mainly explored for energy- and catalysis-related applications to date. This focused review article aims to summarize the recent progress made in the synthesis and biomedical applications of various CuS nanoparticles. After a brief introduction to CuS nanoparticles in the first section, we will provide a concise outline of the various synthetic routes to obtain different morphologies of CuS nanoparticles, which can influence their properties and potential applications. CuS nanoparticles have found broad applications in vitro, especially in the detection of biomolecules, chemicals, and pathogens which will be illustrated in detail. The in vivo uses of CuS nanoparticles have also been investigated in preclinical studies, including molecular imaging with various techniques, cancer therapy based on the photothermal properties of CuS, as well as drug delivery and theranostic applications. Research on CuS nanoparticles will continue to thrive over the next decade, and tremendous opportunities lie ahead for potential biomedical/clinical applications of CuS nanoparticles.

“…Both proteins and polysaccharides are also used in the production of copper sulfide nanoparticles where their role is to act as growth scaffolds and stabilisers. In this manner, amylose and xylan polysaccharides, bovine serum albumin and viral-based proteins have been used to produce well defined copper sulfide nanoparticles (Li et al 2013, Zaman et al 2013, Han et al 2016, Huang et al 2017.…”

Background and Aims: Sulfide-bound Cu in wine may act as a potential source of hydrogen sulfide. The aim of this study was to understand how the white wine matrix can influence the filterability of sulfide-bound Cu. Method and Results: Sulfide-bound Cu was formed in situ with copper(II) sulfate and sodium sulfide addition to white wine and model wines. The amount of subsequent Cu passing through membrane filters was measured by flame atomic absorption spectroscopy or inductively coupled plasma with optical emission spectroscopy. Nanoparticle tracking analysis was utilised to measure the size of particles generated after copper(II) and sulfide addition. The majority of the particles were around or below 0.2 µm, and polyethersulfone and nylon membranes remove up to 40-90 % of sulfidebound Cu from white wine. The regenerated cellulose, teflon and glass fibre membranes removed minimal sulfide-bound Cu. Conclusions: Membrane filtration removed sulfide-bound Cu by adsorption rather than by particle size discrimination. Polysaccharides and proteins were the components of white wine that most inhibited adsorption. Significance of the Study:The addition of copper(II) to wine with hydrogen sulfide results in products that cannot be removed by filtration on the basis of their particle size, but instead may be partly removed by adsorption onto membrane filters to an extent impacted by wine composition and the filtration medium.
