Researchers have developed a titanium bone implant incorporating silver nanoparticles that will help lower infection rates.
Researchers from the Delft University of Technology designed and 3D-printed the porous titanium bone implant. It incorporates strontium, a soft silver-white metallic element that is highly chemically reactive, along with silver nanoparticles. Researches say the combination kills the antibiotic-resistant Staphylococcus aureus (S. aureus) bacteria.
Although silver ions are a common choice to kill the bacteria – and implants are often imbedded with silver for that reason – the researchers suggest that synergistic antibacterial behavior between the strontium and silver may give rise to implants that could outlive the recipient.
The latest edition of Silver News also highlights some other fascinating technological developments utilizing the white metal along with some developments in the silver market.
- Scientists at the Clean Energy Research Center of the Korea Institute of Science and Technology (KIST), working with the Technische Universität Berlin (TUB), have developed a silver catalyst electrode that converts carbon dioxide – a contributor to pollution and climate change – to carbon monoxide in artificial photosynthesis.
- The Silver Institute’s Silver Promotion Service (SPS), which focuses on stimulating demand for silver jewelry, has launched a Virtual Silver Pavilion on the SPS website. The site allows jewelry trade members, media and the general public to browse the newest designs from leading silver designers.
- The US Environmental Protection Agency (EPA) has registered NSPW Nanosilver, a new, active silver-based ingredient that helps suppress odor-causing bacteria, and algae, fungus, mold and mildew that can cause deterioration or staining in textiles, government officials announced.
- The US National Science Foundation has awarded $330,000 to a team of researchers at the University of Pittsburgh to examine the effect that silver, embedded in shower fixtures, has on water disinfection. While many facilities, including hospitals, have installed silver-based water filtration systems to keep disease at bay, facility managers and health officials are concerned that water pipes left unused and unflushed during building closings due to the coronavirus pandemic have become a breeding area for dangerous bacteria. Long stretches of stagnation can result in low to no disinfecting chemicals being present in building water that can create an ideal growth environment for many microbes, the researchers noted.
- Hoping to preserve what they consider the “fading arts and crafts of India, while providing workers with a much-needed livelihood,” Jai and Amrita Dalal established Mishka Gifts in Mumbai, India in 1990. “The idea was to give an impetus to the beautiful handcrafted silver articles manufactured by skilled artisans in rural villages of India,” said Jai Dalal.
- Researchers from Swansea University (UK) have developed an environmentally-friendly, no-solvent approach, for removing toxic chemicals from water. The method employs a newly-invented machine called the Matrix Assembly Cluster Source (MACS), which produces a catalyst composed of silver atoms.
