There ain't half been some clever Barstewards..
The smaller the better
At the nano-scale, copper particles interact easily with bacterial membranes and the integrity of the bacterial cell membranes changes noticeably causing bacterial cell death.
Where surfaces have to be smooth (e.g. tables, walls or display screens) - such as in the cleanroom setting - nano-copper incorporated into a coating is an ideal solution; regular copper particles can result in an uneven, rough finish, providing a perfect surface for microorganisms to adhere to. Additionally, nano-copper has no impact on standard surface functionalities such as abrasion resistance, durability and liquid repellence. In fact, they can be optimised even further by creating different, more complex nanostructures that yield additional benefits. Furthermore, by mixing nanomaterials together, multiple benefits can be accomplished in the same coating.
Regardless of the many practices and processes, the resilient nature of microorganisms means they can be easily spread
When incorporated directly into a substrate, nano-copper can deliver similar antimicrobial benefits to many coating applications. Promethean Particles, based in Nottingham, UK, is home to the world's largest multi-material nanomaterial plant of its kind. It manufactures nano-copper as a liquid dispersion using a unique production process that enables the delivery of high-quality inorganic nanomaterials at scale, reducing cost and process complexities. By manufacturing particles in liquid dispersions, rather than as powders, Promethean avoids the tendency for nanomaterials to agglomerate together. When this happens, the benefits of nanotechnology can be lost.
The company has collaborated with textile companies and leading research facilities as part of an Innovate UK-funded project, ACTIn, to explore the antimicrobial effects of its nano-copper particles when incorporated into fabrics for Personal Protective Equipment (PPE). The requirements for disposal and use of gowns and garments differ according to cleanroom classification and application. Whilst some dispose of PPE after each exit and entry others, with the highest particle thresholds, may only change garments a few times per week.
Eh - Bacteria - I'm in for the VIRUS - pesky BACTERIA- another dimension :)

Aplogies LTH - we all have seen this and been over it - I think a re-post was in order :)
