Gold Nanoparticles Could Turn Trees into Streetlights

Scientists in Taiwan discovered that placing gold nanoparticles in plants made them glow, which could turn them into an effective form of nighttime illumination: By implanting the gold nanoparticles into the leaves of the Bacopa caroliniana plants, the scientists were able to induce the chlorophyll in the leaves to produce a red emission. Under a high [...]

New Breathalyzer Can Detect Lung Cancer

Israeli scientists have invented a breathalyzer-type device that can detect chemical markers for lung cancer in a patient’s breaths. The sensor relies on a film of gold nanoparticles, which conducts electricity, layered over a carbon-based substrate. When a patient breathes into the device, particulates in the breath accumulate on the carbon layer and the sensor swells [...]
