Antibacterial

​Every day, dairies dispose of milk that for one reason or another is deemed unfit for human consumption. A Los Angeles-based startup by the name of Mi Terro is taking some of that milk and using it to create T-shirts, that reportedly have some big advantages over regular cotton Tees.

​The most numerous of organisms on Earth, bacteriophages are viruses that infect and kill bacteria. Now, scientists have grown enough of them to create a self-healing hydrogel that's made almost entirely of the things. It could have important applications in medicine, and in other fields.

​Getting a filling isn't always the end of a tooth's cavity problems. Sometimes, bacteria is able to get down between the filling and the surface of the tooth, causing another cavity to occur. A new antibacterial dental restorative material, however, could help keep that from happening.

​Humans weren’t built for space travel. The immune system takes a beating, leaving us more vulnerable to infection. Astronauts have now tested a new antimicrobial coating on board the International Space Station (ISS), and found it kept space-faring bugs at bay for well over a year.

Hospital-acquired infections are a serious problem, and the most common type of such infections occurs when catheters are inserted into blood vessels. A new coating, however, shows promise for killing bacteria at insertion sites, keeping them from establishing biofilm colonies on the catheters.

Bacteria are a huge problem in hospitals, where colonies can build up on instruments and cause potentially fatal infections in vulnerable patients. Now, researchers at Aston University have developed a new type of antimicrobial material that’s made using a centuries-old stained glass technique.

​Although it's important to get vaccines to people in developing nations and elsewhere, it's also crucial that those medications subsequently be administered in a safe and sterile manner. A new microneedle patch could help, as it incorporates bacteria-killing silver.

​While it's important to keep food of any type fresh, it's particularly crucial with seafood, as it can become tainted with toxic bacteria. That's why an international group of scientists is developing a transparent antibacterial film that gets eaten along with the seafood it's covering.

​Medical devices such as catheters extend from within a patient's body out through an opening in their skin, and unfortunately those openings often become infected. Thanks to new research, however, ultraviolet optical fibers may eventually keep such infections from occurring.

​For centuries, various cultures have used clay as a remedy for infections. Now, scientists from Arizona State University (ASU) and the Mayo Clinic have determined that blue clay in particular may indeed be effective at treating infected wounds.

​The scratches that form on stainless steel may seem minuscule to us, but they provide a haven for microscopic bacteria. Scientists at the University of Toronto have developed a method of making those scratches less hospitable to the microbes, using a surprisingly simple substance – cooking oil.

​It's never a good thing when donated human blood – or even the blood in our bodies – is infected with bacteria. Scientists at the University of California San Diego, however, are developing a means of removing such blood-borne microbes using tiny ultrasound-powered robots.
