January 21, 2011 –
High-energy costs are one drawback of making clean water from waste effluents. According to an article in
the journal Biomicrofluidics, published by the American Institute of Physics, a
new system that combines two different technologies proposes to break down
contaminants using the cheapest possible energy source, sunlight. Microfluidics
– transporting water through tiny channels – and photocatalysis – using light
to break down impurities – come together in the science of optofluidics.
