Antibacterial

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.
-
While antibiotics are very effective at treating infected wounds, they should definitely be used sparingly. An experimental new bandage was designed with this fact in mind, as it only dispenses medication when it detects the heat of an infection.
-
For some time now, antimicrobial bioactive glass has been put forward for use in applications such as medical implants, hospital surfaces and wound dressings. Now, scientists report they have boosted its bacteria-killing effect by over 100 times.
-
Researchers have developed a simple new way to make material surfaces with intricate nanoscale textures, all inspired by nature. Different patterns have a range of applications, like making antimicrobial surfaces or reducing ship hull friction.
-
Red wine and chocolate are notorious for staining clothes, thanks to the tannic acid that they contain. Scientists at the University of Tokyo have now used that acid in a textile coating which keeps clothes from stinking, and that doesn't wash out.
-
It's ironic that even though many people are starving, a great deal of food gets discarded because it spoils before it can be eaten. A new natural-source packaging material could help, by making foods last longer – plus it's biodegradable.
