Unexpected Discovery Leads to New Theory of Liquid Streaming

Researchers at the University of Houston were studying the nonlinear transmission of light through an aqueous suspension of gold nanoparticles when they noticed something unexpected. A pulse laser appeared to have forced the movement of a stream of liquid in a glass laboratory cuvette.
As they investigated, they realized something more complex was a work than a transfer of momentum from the laser photons to the liquid. Their observation led to a new optofulidics principle, explained in a paper published Sept. 27 in the journal Science Advances.
