Germ-repelling surfaces -

Each had been exposed to a nasty, disease-causing germ. They chose to work with Staphylococcus aureus bacteria.

Also known as staph, these germs can cause skin infections, including boils, or worse. The scientists used one strain of the bacterium that antibiotic medicines can kill. They also used a resistant form that is immune to the germ-fighting effects of many drugs.

That germ is known as methicillin-resistant Staphylococcus aureus , or MRSA. The experiments attempt to mimic how germs spread in the real world.

Surfaces pick up germs as people cough into their hand and then touch a door handle. Or an infected person might sneeze on a laptop.

Or someone could spill a drink after it had touched his mouth. For the spill test, the researchers submerged a surface into a bacteria-tainted solution for an hour. Then they rinsed and dried it.

To mimic sneezing, they loaded bacterial solutions into a paint sprayer to spew a tainted mist. They then pressed the cloth onto surfaces. Under all conditions, the bumps on the sharkskin-inspired surface retained far fewer bacteria than did the smooth plastic surface.

Copper repelled MRSA nearly as well as the surface with microbumps. However, copper was virtually powerless in repelling the attachment of regular staph germs. Unlike antibiotics and other chemicals, the microbumps do not kill bacteria.

Instead, they make it hard for the microbes to latch on. The bacteria are 1 to 3 micrometers in size. The surface ridges are about 2 micrometers apart.

He thinks the lack of an active kill mechanism makes the new surface treatment attractive. It avoids the problem of germs developing a resistance to it, he says. Otter blogs about infection control and is a scientific director at Bioquell, a company that develops superbug-decontamination products.

He says that the texture may have a downside. Otter suspects it might be safer to combine an active germ-killer with a surface repellent such as the new microridges. As aquatic organisms, they grow in water. Like green plants, they depend on sunlight to make their food.

In total this structure works much like the lotus leaf, and bacteria find it as slippery and hard to stick to as water droplets. Didar and his McMaster University colleagues tested their self-cleaning surface with three different superbugs: Staphylococcus aureus MRSA , Pseudomonas aeruginosa and E.

Their material prevented approximately 90 per cent of the bacteria from attaching to the surface, but more importantly, they were able to prevent the formation of biofilm, which Didar said is key to prevent contamination that would allow another person to pick up and transfer elsewhere.

3 Antimicrobial Surfaces That Repel Germs For A Cleaner Home | Storables

Over the past decade or so, the list of medicines we can use against harmful bacteria has been dwindling. At the same time, other disease-causing organisms — fungi, viruses and parasites — are also developing resistance to the drugs we use to tackle them almost as quickly as we can make new ones.

It means the illnesses they cause are getting harder to treat. He is among those looking for new ways to tackle antimicrobial resistance. His plan is to turn the very surfaces that many of these pathogens use to spread from person to person into weapons against them.

Indeed, the virus that causes Covid — Sars-CoV-2 — can persist on cardboard for up to 24 hours, while on plastic and stainless steel it can remain active for up to three days. Some bacteria — including E. Coli and MRSA — can survive for several months on inanimate surfaces, while infectious yeasts can last for weeks.

This only underlines the importance of continually disinfecting and cleaning surfaces that are frequently touched. Read more about how long Covid lasts on surfaces.

Using antimicrobial metals or surfaces on frequently touched hotspots like door handles, lift buttons and taps could reduce the risk of transmission Credit: Alamy. By simply changing the texture of the surfaces we use, or coating them with substances that kill bacteria and viruses more quickly, some scientists hope it may be possible to defeat infectious organisms before they even get into our bodies.

Larrouy-Maumus is betting on copper alloys. The ions in copper alloys are both antiviral and antibacterial, able to kill over Copper is even more effective than silver, which requires moisture to activate its antimicrobial properties. It is expensive and harder to clean without causing corrosion, and many people dislike such materials.

Not everyone wants to sit on a metallic toilet seat, for instance. Copper surfaces can also be treated with lasers to create a rugged texture that increases the surface area — and, by extension, the number of bacteria it can kill.

Researchers at Purdue University, in Indiana, who developed the technique found it could kill even highly concentrated strains of antibiotic-resistant bacteria in just a couple of hours.

Such treatments could not only be useful for door handles, but could also help to make medical implants such as hip replacements less likely to cause infection. Their wings are superhydrophobic, meaning that water droplets bounce off them, just as they do off lotus leaves, allowing contaminants to roll off with the water.

Controlling antibiotic-resistant bacteria in hospitals is becoming a major challenge that if left unchecked could claim many lives Credit: Alamy. The technique might apply to metallic alloys that also are known to have antimicrobial properties. Metals such as copper normally have a really smooth surface, which makes it difficult for the metal to kill bacteria by contact.

The patterns produce a rugged texture that increases surface area, allowing more opportunity for bacteria to hit the surface and rupture on the spot. Researchers in the past have used various nanomaterial coatings to enhance the antimicrobial properties of metal surfaces, but these coatings are prone to leach off and can be toxic to the environment.

The laser-texturing has a dual effect: The technique not only improves direct contact, but also makes a surface more hydrophilic. For orthopedic implants, such a surface allows bone cells to more strongly attach, improving how well the implant integrates with bone.

Due to the simplicity and scalability of the technique, the researchers believe that it could easily be translated into existing medical device manufacturing processes.

This research was performed at the Birck Nanotechnology Center in Purdue's Discovery Park. Discovery Park is a place where Purdue researchers move beyond traditional boundaries, collaborating across disciplines and with policymakers and business leaders to create solutions for a better world.

Grand challenges of global health, global conflict and security, and those that lie at the nexus of sustainable energy, world food supply, water and the environment are the focus of researchers in Discovery Park.

The translation of discovery to impact is integrated into the fabric of Discovery Park through entrepreneurship programs and partnerships.

Ranked the No. Committed to hands-on and online, real-world learning, Purdue offers a transformative education to all. So he incorporated the sharkskin pattern onto his test panels.

And that cut the buildup of green algae by 85 percent. Brennan later discovered, somewhat by accident, that this same texture also inhibits the attachment of germs, including those that cause human disease. That led to his founding of Sharklet Technologies in New tests have now quantified how well the texture repels germs.

Sharkskin-inspired surfaces collect and hold 94 percent fewer bacteria than do smooth surfaces. The bumpy surfaces even perform better than copper, a widely used germ-fighter. The new findings are a good example of how researchers can learn useful tips from Mother Nature. Adopting such lessons is known as biomimicry.

Each had been exposed to a nasty, disease-causing germ. They chose to work with Staphylococcus aureus bacteria. Also known as staph, these germs can cause skin infections, including boils, or worse. The scientists used one strain of the bacterium that antibiotic medicines can kill.

They also used a resistant form that is immune to the germ-fighting effects of many drugs. That germ is known as methicillin-resistant Staphylococcus aureus , or MRSA. The experiments attempt to mimic how germs spread in the real world.

Surfaces pick up germs as people cough into their hand and then touch a door handle. Or an infected person might sneeze on a laptop. Or someone could spill a drink after it had touched his mouth. For the spill test, the researchers submerged a surface into a bacteria-tainted solution for an hour.

Then they rinsed and dried it. To mimic sneezing, they loaded bacterial solutions into a paint sprayer to spew a tainted mist. They then pressed the cloth onto surfaces. Under all conditions, the bumps on the sharkskin-inspired surface retained far fewer bacteria than did the smooth plastic surface.

Copper repelled MRSA nearly as well as the surface with microbumps. However, copper was virtually powerless in repelling the attachment of regular staph germs. Unlike antibiotics and other chemicals, the microbumps do not kill bacteria.

Instead, they make it hard for the microbes to latch on. The bacteria are 1 to 3 micrometers in size. The surface ridges are about 2 micrometers apart. He thinks the lack of an active kill mechanism makes the new surface treatment attractive.

To create a microbe-repelling surface scientists borrowed a handy trick from the lotus leaf — its self-cleaning properties. He and his team were inspired by the lotus to create an innovative solution to curb the spread of bacteria, including potentially deadly antibacterial resistant bacteria.

Didar and his colleagues at McMaster University in Hamilton, developed a non-stick coating they could apply to plastic that in turn they can shrink-wrap onto surfaces — such as a stethoscope or a doorknob. This could prevent bacteria from colonizing these objects and forming a fortress-like biofilm.

When bacteria attach to a surface, they form communities that create a layer of slimy, slippery biofilm that protects the microbes from scrubbing, disinfectants and even antibacterial compounds. This technology could be important in the battle against superbugs. According to Health Canada, antibiotic resistant superbugs are currently the fourth leading cause of death in our country — a problem experts expect to get a lot worse as more bacteria evolve resistance to our current roster of antibiotic medications.

If you were to zoom right down to the surface of the lotus leaf, you'd see a structure kind of like a series of rolling hills, covered in trees and then flowers on those trees. This surface is slippery because these structures trap air pockets between themselves and water droplets, for example.

Invented more than years ago, this eco-friendly material is naturally antibacterial and hypoallergenic. Not to be confused with vinyl, linoleum is made from renewable, biodegradable materials including linseed oil, powdered cork, wood flour, pine resins, and mineral pigments and mounted on canvas or jute backing.

This durable, water-resistant flooring holds up well in high-traffic or moisture-prone areas including entryways, kitchens, and bathrooms. Plus, it's easy to install and comes in a wide variety of colors and patterns.

The density and geometry of the pattern needed, and the method and materials for producing it, will depend on the features of the microbe being targeted. Ivanova says that complex zigzag shapes would be especially effective in water and air conditioner filters.

These can be hydrothermally etched : essentially the metal can be melted by high temperature and pressure, forming a fine sheet with sharp edges that can kill different types of bacteria. And titanium dioxide when exposed to UV light produces reactive oxygen species, such as peroxides, which inactivate microbes.

This has been harnessed to coat dental braces , for instance, to reduce bacteria. Even exposing these kinds of coatings to commercial lamps for four hours could reduce the number of viable bacteria 1,fold.

But Vladimir Baulin, a biophysicist at the Universitat Rovira i Virgili in Spain, believes similar techniques can be used with viruses, including coronavirus.

One strategy would be to essentially trap the viral particles between nanopillars — tiny pillar-shaped structures that can be synthetically produced on a surface. This could help to collect the virus particles so scientists can develop tests and vaccines. Nature also offers other ways we can make the surfaces around us more resilient to the spread of disease.

Take tea tree oil, that strong-smelling substance that has inspired a number of beauty product ranges. Cork has been shown to be highly antibacterial against Staphylococcus aureus. And extracts from hops have been used to create plastic-like coatings that can prevent the growth of certain types of bacteria.

However, research on the potential surface-coating applications of antimicrobial plant extracts is still largely in the experimental stages. Theoretically these kinds of plant materials could be turned into germ-fighting coatings, but much more would need to be known about the amounts of key ingredients needed and the types of microorganisms they would target.

Replicating the tiny spikes on the surface of cicada wings could prevent bacteria from settling and forming colonies Credit: Alamy. But overall, the potential applications for antimicrobial surfaces are numerous. However, we must not become over reliant upon this kind of approach, warns Mengying Ren, a policy officer at the network ReAct — Action on Antibiotic Resistance , based in Sweden.
