N2  - Microrheology studies are based on Brownian motion (BM) of particles. The main
causes of BM are thermal fluctuation and viscosity of medium. One of the
microrheological methods is single probe study using Optical Tweezers (OT) to
extract information about the material characteristics. The OT uses single particle,
which undergoes BM. For analysis of the BM, we need Power Spectrum Density
(PSD). Therefore, this paper discuss on the simulation of the PSD calculation of
single particle in liquid. We generate random number, which represent the
displacement of the particle for on allocated period of time. The PSD is calculated
using Origin Pro 9.1. The resulted PSD is useful for further investigations, for
example in characterization of storage and loss modulus of a material.
