Algae-based thread will keep your clothes odor-free
If you're worried that the silver ions in antibacterial and anti-odor clothing might also pose serious health risks, like destroying genetic material, you'll be glad to hear that there should soon be a safer alternative. The KTH Royal Institute of Technology has developed an antibacterial thread that uses a mix of bio-compatible plastics and lanosol, a bacteria-fighting compound that you normally find in red algae. The material should not only be a less contentious germ-killer than silver, but more effective. Because it's woven into super-thin fibers through electrospinning (which uses electrical charges to draw thread from liquid), the antiseptic element doesn't clump up and leave some areas unprotected.
Hybrid 3D printer could fast-track cartilage implants
Most of the attention surrounding 3D printers in medicine has focused on patching up our outsides, whether it's making skin to heal wounds or restoring the use of limbs. The Wake Forest Institute for Regenerative Medicine has just detailed a technique that could go considerably deeper. By mixing natural gel put through an inkjet printer with thin and porous polymer threads coming from an electrospinner, researchers have generated constructs that could be ideal for cartilage implants: they encourage cell growth in and around an implant while remaining durable enough to survive real-world abuse. Early tests have been confined to the lab, but the institute pictures a day when doctors can scan a body part to produce an implant that's a good match. If the method is ultimately refined for hospital use, patients could recover from joint injuries faster or more completely -- and 3D printers could become that much more integral to health care.
