Optofluidic applications with lithium niobate nanowires
We report the hydrothermal synthesis of free-standing lithium niobate nanowires. We show that the versatile properties of bulk lithium niobate such as nonlinear optical effects can be exploited at the nanoscale. We describe the fabrication of polydimethylsiloxane (PDMS) microfluidics as well as indium tin oxide (ITO) electrodes with different design for dedicated applications. The control of microfluidic channel dimensions and the corresponding particle concentration is explored. Finally, the selection of fluidic conductivity for optimal dielectrophoretic trapping conditions is discussed.
