Nano: a cleaner option?

InterNano Industry News - February 16, 2017 - 4:45am
Could nanotechnology tidy up the planet without leaving a dangerous residue of its own?It's likely that you've recently swirled nanotechnology down your sink. Antimicrobial silver nanoparticles, for example, are added to food containers, socks, and cleaning products such as floor polish. But could nanoparticles – measuring less than 100 nanometres wide – clean more than just your house? Could nanotechnology tidy up the planet without leaving a dangerous residue of its own?The European Environment Agency estimates that "potentially polluting activities" have occurred at nearly three million EU sites. But nanoparticles could remediate water, soil and air polluted by compounds such as heavy metals and aromatic hydrocarbons. With high reactivity and a larger surface area than the same mass of material in a larger form, nanoparticles are prime candidates for capturing and destroying pollutants. Continue reading...
