Bacteria adapt and evade nanosilver's sting

(Phys.org) —Researchers from UNSW have cautioned that more work is needed to understand how micro-organisms respond to the disinfecting properties of silver nano-particles, increasingly used in consumer goods, and for medical ...

Investigating the environmental impact of nanosilver

When it comes to materials used in the fight against bacteria, silver may not be the first substance which comes to mind. However, the precious metal has been used in the medical industry as a biocide - a substance which ...

Ingested nanoparticle toxicity

Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures ...

Study sheds new light on antibiotics produced by ants

Ants, like humans, deal with disease. To deal with the bacteria that cause some of these diseases, some ants produce their own antibiotics. A new comparative study identified some ant species that make use of powerful antimicrobial ...

Nanosilver in textiles – friend or foe?

Antimicrobial silver nanoparticles may enable people to use textiles in an environmentally more sustainable way, even though a question mark remains on their potential risks

Bringing back extinct molecules to fight modern bacteria

A team of microbiologists and bioengineers at the University of Pennsylvania has tested the possibility of bringing back extinct molecules to fight modern bacteria. In their study, reported in Cell Host & Microbe, Jacqueline ...

Study examines nanotechnology-related safety and ethics problem

A recent paper by Kathleen Eggleson, a research scientist in the Center for Nano Science and Technology (NDnano) at the University of Notre Dame, provides an example of a nanotechnology-related safety and ethics problem that ...
