Scientists write `traps´ for light with tiny ink droplets
(World News Science)

The printing-based approach, jointly developed by researchers at the University of Cambridge and the Hitachi Cambridge Laboratory, combines high-resolution inkjet printing with nanophotonics - the study and harnessing of light on the scale of a billionth of a metre - the first time that this combination has been successfully demonstrated. The results are reported in the journal Advanced Materials. Over the last decade, inkjet printing - the same basic technology that many of us have in our homes - has advanced to the point where it can be used to print very small devices, using a range of printable materials, including living cells, as `ink`.
