Antibacterial

Decades of work has paid off, with scientists developing a potent new synthetic molecule that swiftly knocked out 285 strains of bacteria it was tested on, setting it up as a valuable ally in our fight against a looming superbug infection crisis.

Although HEPA filters and UV lights are effective at neutralizing bacteria in hospitals, homes and other settings, they do have their drawbacks. A new light-activated material known as LumaFlo, however, is claimed to have them both beat.

A novel microneedle patch may bring new hope to people who struggle to keep their acne under control. Instead of utilizing antibiotics, the device releases nanoparticles that kill acne-causing bacteria when triggered by exposure to ultrasound.

Science continues to make advances in smart fabrics. Now, a team of international researchers has created a wearable textile that can self-repair, is antibacterial, and could even be used to monitor a person’s heart rhythm.

Scientists at the University of Georgia have created a "superfoam" with two very valuable potential applications. It could be used not only to clean up oil spills, but also to keep infections from occurring at medical implant sites.

While most of us wouldn't dream of not washing our spoons or forks after each use, we have no problem repeatedly using – or sharing – a never-washed tube of lipstick. That's why scientists have developed a cranberry-fortified antimicrobial lipstick.

While it would be great if there were a simple method of eradicating all the harmful bacteria present on food, dousing that food in antibiotics certainly wouldn't be the way to go. A new spray, however, uses food-safe viruses that kill such bacteria.

People with cystic fibrosis are vulnerable to potentially fatal Mycobacterium abscessus lung infections, which are notoriously difficult to treat. A new treatment may succeed where others have failed, however – and it utilizes antibacterial honey.

Although there are coatings that kill harmful microbes on frequently touched surfaces, most of those substances either have to be frequently reapplied, or they take a long time to work. A new coating, however, is claimed to address both shortcomings.

Copper is known for its ability to kill microbes on contact, which is why it's often professionally coated onto commonly touched items. A copper nanowire spray may allow everyday folks to give existing surfaces the same treatment, using a spray can.

Plastic wraps and food containers generate huge amounts of waste. Now researchers at Harvard and Rutgers have developed a new plant-based, antimicrobial coating that can be sprayed onto food to keep it fresh, and easily washed off before consumption.

Because seeds may contain yield-reducing fungi, bacteria or viruses, they're often chemically treated before they're sold to farmers. A new mobile system, however, substitutes microbe-killing electrons for harsh and eco-unfriendly chemicals.
