Unfolding of a diblock chain and its anomalous diffusion induced by active particles
Yi-qi Xia, Zhuang-lin Shen, Wen-de Tian +2
We study the structural and dynamical behaviors of a diblock copolymer chain in a bath of active Brownian particles (ABPs) by extensive Brownian dynamics simulation in a two-dimens…
Transition between globule and stretch states of a self-attracting chain in the repulsive active particle bath
Yi-qi Xia, Wen-jie Shan, Wen-de Tian +2
Folding and unfolding of biopolymers are often manipulated in experiment by tuning pH, temperature, single-molecule force or shear field. Here we carry out Brownian dynamics simula…
Beating of grafted chains induced by active Brownian particles
Qiu-song Yang, Qing-wei Fan, Zhuang-lin Shen +3
We study the interplay between active Brownian particles (ABPs) and a hairy surface in two dimensional geometry. We find that the increase of propelling force leads to and enhances…
Spontaneous symmetry breaking induced unidirectional rotation of chain-grafted colloid in the active bath
Hui-shu Li, Chao Wang, Kang Chen +2
Exploiting the energy of randomly moving active agents such as bacteria is a fascinating way to power a microdevice. Here we show, by simulations, that a chain-grafted disk-like co…
