A spoonful of sugar in silver nanoparticles to regulate their toxicity

The use of colloidal silver to treat illnesses has become more popular in recent years, but its ingestion, prohibited in countries like the U.S., can be harmful to health. Scientists have now confirmed that silver nanoparticles are significantly toxic when they penetrate cells, although the number of toxic radicals they generate can vary by coating them with carbohydrates.

An electron takes 40 attoseconds to pass through a single layer of atoms

An international team of researchers has measured how fast an electron races through the atomic layers of a crystal lattice. The physicists used an extremely short laser pulse to time the speed: According to their measurements, the electron needs 40 attoseconds to pass through one layer of magnesium atoms.

Wearable nanowire sensor clears path to long-term EKG, EMG monitoring

Researchers have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.
