Direct experimental measurement of many-body hydrodynamic interactions with optical tweezers

|
By Dae Yeon Kim, Sachit G Nagella, Kyu Hwan Choi
| Physical Review B
Many-body hydrodynamic interactions (HIs) play an important role in the dynamics of fluid suspensions. While many-body HIs have been studied extensively using particle simulations, there is a dearth of experimental frameworks with which to quantify fluid-mediated multibody interactions. To address this, we design an experimental method that utilizes optical laser tweezers for quantifying fluid-mediated colloidal interactions with exquisite precision and control.

Dynamic interfaces for contact-time control of colloidal interactions Yaxin Xu, Kyu Hwan Choi, Sachit G Nagella and Sho Takatori Abstract Understanding pairwise interactions between colloidal particles out of equilibrium has a profound impact on dynamical processes such as colloidal self assembly. However, traditional colloidal interactions are effectively quasi-static on colloidal timescales and cannot be modulated out of equilibrium.
