We are excited to share a recent publication that highlights the exceptional quality and suitability of our monodisperse amino PMMA latex particles for cutting-edge research in fluid dynamics!
A study titled "Direct experimental measurement of many-body hydrodynamic interactions with optical tweezers" published on February 14, 2025 by a research group from Stanford (Dae Yeon Kim et.al) utilized Abvigen's monodisperse PMMA latex particles in their innovative experimental method.

This movie demonstrates the time-dependent rotational Brownian motion of a hemispherical fluorescent PMMA particle under very weak optical trap stiffness.

This publication presents a novel experimental method using optical laser tweezers to quantify fluid-mediated colloidal interactions with remarkable precision and control. The authors successfully used our PMMA particles to induce translation-rotation hydrodynamic coupling between trapped fluorescently-labeled colloids. This method provides a direct reporter of few- to many-body hydrodynamic interactions.
The researchers were able to precisely quantify distant fluid disturbances generated by forces as small as ~2 pN at a separation of 12 particle radii, a testament to the sensitivity of their method and the quality of the materials used, including Abvigen's particles.
This publication serves as a strong validation of the quality and suitability of Abvigen's monodisperse amino PMMA latex particles for researchers working on fundamental and applied problems in colloidal science, fluid dynamics, and materials engineering.
