In this paper, the general Langevin equations of motion for the polystyrene bead linked to the lambda-phage worm-like chain DNA molecule embedded in the fluid under the nonlinear optical tweezers is derived in 3D space. Using the finite difference method, the dynamical properties of the bead trapped by the nonlinear optical tweezers using a thin layer of Acid Blue 29 are numerically studied. Results in, the stretched length of the lambda-phage worm-like chain DNA molecule can be controlled in 3D space by finely tuning of the laser power.
