Observation of the Brownian motion of individual microobjects in liquids for small time and spatial scales

Detection of Pathogens in Water Using Micro and Nano-Technology

“…Due to the high but limited number of collisions, the net momentum transferred to the particle per unit time will not be zero (R. Kubo, 1978), which results in the acceleration of the particle. The purely "thermal" description of Brownian motion has been questioned, and although the existing models still offer a good qualitative and quantitative description, its exact physical characterisation is currently a re-opened problem (S. N. Bagayev & Panov, 2007). Brownian motion forms the basis of the meta-models of macromolecule motion.…”
