“…Additionally, plasma can easily treat objects with complex geometries and high surface areas. Numerous studies have therefore explored plasma surface treatments for surgical meshes (Avetta et al, 2014;Binnebösel et al, 2012Binnebösel et al, , 2010Gorgieva et al, 2015;Hu et al, 2017;Junge et al, 2007;Kulaga et al, 2014;Kumar et al, 2013;Labay et al, 2015;Lanzalaco et al, 2019;Lu et al, 2019;Nisticò et al, 2017Nisticò et al, , 2015Nisticò et al, , 2013Nisticò et al, , 2012Paul et al, 2010;Rivolo et al, 2016;Sanbhal et al, 2019Sanbhal et al, , 2018bSannino et al, 2005;Zhang et al, 2014).…”

Plasma-based treatment is a prevalent strategy to alter biological response and enhance biomaterial coating quality at the surfaces of biomedical devices and implants, especially polymeric materials. Plasma, an ionized gas, is often thought to have negligible effects on the bulk properties of prosthetic substrates given that it alters the surface chemistry on only the outermost few nanometers of material. However, no studies to date have systematically explored the effects of plasma exposure on both the surface and bulk properties of a biomaterial. This work examines the time-dependent effects of a nonthermal plasma on the surface and bulk properties of polymeric implants, specifically polypropylene surgical meshes and sutures. Findings suggest that plasma exposure improved resistance to fibrinogen adsorption and Escherichia coli attachment, and promoted mammalian fibroblast attachment, although increased duration of exposure resulted in a state of diminishing returns. At the same time, it was observed that plasma exposure can be detrimental to the material properties of individual filaments (i.e. sutures), as well as the structural characteristics of knitted meshes, with longer exposures resulting in further embrittlement and larger changes in anisotropic qualities. Though there are few guidelines regarding appropriate mechanical properties of surgical textiles, the results from this investigation imply that there are ultimate exposure limits for plasma-based treatments of polymeric implant materials when structural properties must be preserved, and that the effects of a plasma on a given biomaterial should be examined carefully before translation to a clinical scenario.

Imaging XPS has been available on commercial XPS instruments since the 1990's, however its exploitation in the elucidation of surface chemistry has been minimal due to historical limitations in spatial resolution and acquisition times. Major developments in both instrumentation and multivariate data analysis techniques have improved greatly on all these aspects and herein a range of imaging analysis to illustrate the power of XPS imaging to a diverse range of industrial sectors is presented.

Silver bismuth sulphide is a ternary material that has attracted attention due to its good properties and several applications. Here, the detailed methods of synthesizing silver bismuth sulphide including successive ionic layer and reaction, Bridgman, microwave, mechanical milling, pyrolysis, deposition, sol–gel and chemical methods are discussed. To understand the properties of the silver bismuth sulphide, characterization tools are required, some of these tools are highlighted. Its photocatalytic, sensing, photovoltaic, photothermal, hydrogen generation, usage in the treatment of cancer and other medical applications are also comprehensively reviewed. Lastly, future perspectives on the synthesis and applications of silver bismuth sulphide are suggested.
