What exactly is Google's 'cancer nanodetector'?

Last week, US tech giants Google made a splash in the media, announcing plans to develop new 'disease-detecting magnetic nanoparticles'. This was almost universally welcomed – after all, trying to detect diseases earlier ...

Intricate algae produce low-cost biosensors

(Phys.org) —Oregon State University researchers are combining diatoms, a type of single-celled photosynthetic algae, with nanoparticles to create a sensor capable of detecting miniscule amounts of protein or other biomarkers.

Cut flowers last longer with silver nanotechnology

Once cut and dunked in a vase of water, flowers are susceptible to bacterial growth that shortens the length of time one has to enjoy the blooms. A few silver nanoparticles sprinkled into the water, might be the answer to ...

Targeting tumors using silver nanoparticles

Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique—and important—properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide that enables ...

Ecotoxicity: All clear for silver nanoparticles?

It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how ...

Some antibacterials come with worrisome silver lining

Silver has long been known for its ability to kill some of the nasty microbes that can make people sick. In hospitals, it's used to help burn victims, to combat germs on catheters and even to wipe out dangerous "superbugs" ...
