Abstract
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.
