Feedback-controlled solute transport through chemo-responsive polymer membranes
Sebastian Milster, Won Kyu Kim, Joachim Dzubiella
Polymer membranes are typically assumed to be inert and nonresponsive to the flux and density of the permeating particles in transport processes. Here, we study theoretically the c…
Active diffusion of self-propelled particles in flexible polymer networks
Yeongjin Kim, Sungmin Joo, Won Kyu Kim +1
Biopolymer networks having a meshwork topology, e.g., extracellular matrix and mucus gels, are ubiquitous. It is an open question to understand how self-propelled agents such as Ja…
Nanochannels and nanodroplets in polymer membranes controlling ionic transport
Matej Kanduč, Rafael Roa, Won Kyu Kim +1
Polymer materials with low water uptake exhibit a highly heterogeneous interior, characterized by water clusters in the form of nanodroplets and nanochannels. Here, based on our re…
Transport in polymer membranes beyond linear response: Controlling permselectivity by the driving force
Won Kyu Kim, Sebastian Milster, Rafael Roa +2
In the popular solution-diffusion picture, the membrane permeability is defined as the product of the partition ratio and the diffusivity of penetrating solutes inside the membrane…
Polymer brush-induced depletion interactions and clustering of membrane proteins
Anvy Moly Tom, Won Kyu Kim, Changbong Hyeon
We investigate the effect of mobile polymer brushes on proteins embedded in biological membranes by employing both Asakura-Oosawa type of theoretical model and coarse-grained molec…
Tuning the Selective Permeability of Polydisperse Polymer Networks
Won Kyu Kim, Richard Chudoba, Sebastian Milster +3
We study the permeability and selectivity (`permselectivity') of model membranes made of polydisperse polymer networks for molecular penetrant transport, using coarse-grained, impl…
