Next, the random forces driving Brownian motion cancel each other out due to their positive and negative values, resulting in an average of zero. Therefore, we introduced the averaged absolute random force. Consequently, unlike the previously mentioned averaged absolute thermophoretic force, the averaged absolute random force was not divided into small regions; instead, the average of all generated absolute random forces was plotted. Here, the averaged absolute random force driving Brownian motion was 229 fN. Examining Fig. , it is evident that the averaged absolute thermophoretic force in this system does not exceed the averaged absolute random forces driving Brownian motion. However, the results in Fig. confirm the observation of thermophoretic behavior. This can be attributed to the fact that displacements due to Brownian motion are averaged out, whereas thermophoresis is consistently observed as a movement away from the center, giving the appearance that diffusion behavior is dominated by thermophoresis.
