Abstract
A probe-based bidirectional electrophoretic force optical trap loading method includes steps of () detaching target particles from an upper electrode plate and capturing the target particles by a micro-scale probe based on a bidirectional electrophoretic force; () moving the probe with the target particles over an optical trap, applying a reverse electric field between the probe and the upper substrate electrode plate which is applied during a polar relaxation time of the target particles, and desorbing the target particles from the probe; and () turning on the optical trap, applying an electric field between the lower electrode plate and the upper electrode plate, adjusting the speed of the desorbed target particles through the electric field at which the optical trap is able to capture the desorbed target particles and the desorbed target particles moving to the effective capture range of the optical trap.
