Simulation and production of reconfigurable opto-electronic traps on iron doped Lithium Niobate substrate

Program Opto-electronics tweezers are a promising technique for the realization of fast, highly-reconfigurable array of traps for particle immobilization and manipulation. Exploiting a photoconductive substrate, like Lithium Niobate, a static electric field induced by light can be used to trap a particle, either a cell or an inorganic neutral object by means of a dielectrophoretic force. LN is a very promising material thanks to the presence of the photorefractive effect, that is the insurgence of a semi- permanent yet erasable electric field, called space-charge field, when is illuminated with a light in the visible range. This work combines the known numerical results on photorefractive effect to calculate the dielectrophoretic force on particles suspended in a buffer solution, lying on top of the LN sample surface. An experimental validation of the simulation results was also performed using Poly-methyl-methacrylate beads suspended in paraffin oil on an iron doped LN sample (Fe: LiNbO3).
