Antibacterial

It's never a good thing when harmful bacteria are present on surfaces in hospitals, as they can cause life-threatening infections in patients. A new paint could help keep that from happening, by quickly killing any microbes that land on it.

While we've seen antibacterial wound dressings before, Italian scientists have taken the idea to new extremes. They've created a material that kills multiple types of harmful bacteria, and it does so using tiny flowers.

Researchers have discovered that proteins found in oyster blood have bacteria-killing properties and can boost the effectiveness of some common antibiotics whose use has been negatively affected by the global rise in drug resistance.

When someone receives an implant such as an artificial hip, there's a real risk of an infection occurring at the implant site. According to a new study, however, a covering of bacteria-frying gold nanorods could keep that from happening.

If there's one thing that needs to be antibacterial, it's the public touchscreen displays that everyone paws at with their filthy fingers. Well, help is on the way, in the form of a newly developed copper coating.

The four spikes on a new nanocrystal developed in Spain spin up under light and move through liquid, blasting any bacteria unfortunate to be in their path. The development could spell trouble for bacteria that resists traditional drug treatments.

Mussels and silkworms may soon be indirectly responsible for saving people's lives. Scientists have used proteins from both animals to develop an internal wound dressing that stops bleeding and prevents infections.

While infected wounds aren't a good thing, neither is the proliferation of antibiotic-resistant bacteria which may occur due to overuse of the drugs. That's where a new type of bandage comes in, as it kills microbes without resorting to antibiotics.

Hospitals are meant to heal people, but patients often pick up superbugs during their stay. Scientists have now developed long-lasting antimicrobial coatings for textiles that could allow hospital curtains to quickly kill viruses and bacteria.

While titanium implants such as artificial hips can greatly improve patients' lives, they're also subject to serious bacterial infections. An experimental new antibacterial titanium alloy, however, could make such problems a thing of the past.

Ordinarily, when treating chronic wounds, caregivers go to great lengths to keep them free of bacteria. An experimental new dressing, however, actually introduces bacteria to help such wounds heal.

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.
