The researchers — from Seoul National University, Act Company and Minuta Technology — used an array of
microscale prisms placed on a screen to
create a filter that guides the light in one direction or another.
Creating organ models on a
microscale has been greatly facilitated by microfluidics, a technology developed in the 1990s that uses micropumps, valves and finely etched channels to manipulate the movement of fluids through a chip.
