Control of filament network rigidity by the condensation of crowding molecules
Jiyong Cheon, Zhengyan Lin, Dean Kim +2
Understanding how liquid-liquid phase separation impacts the mechanics of filament networks is a fundamental physical problem at the heart of biological cellular processes and soft…
Anisotropic Diffusion in Lyotropic Chromonic Liquid Crystal using Fluorescence Recovery After Photobleaching
Kyu Hwan Choi, Jiyong Cheon, Joonwoo Jeong +1
Anisotropic diffusion governs transport in a wide range of soft and biological materials, where microstructure and molecular interactions jointly shape how matter moves. Here, we q…
Solvent isotopic effect on the phase transition of lyotropic chromonic liquid crystals: Heavy water makes mesogens less charged
Jiyong Cheon, Joonwoo Jeong
The interplay among solute and solvent molecules in lyotropic mesophases governs their physicochemical properties, such as phase behaviors and viscoelasticity. In our model system,…
Motility Modulates the Partitioning of Bacteria in Aqueous Two-Phase Systems
Jiyong Cheon, Kyu Hwan Choi, Kevin J. Modica +3
We study the partitioning of motile bacteria in an aqueous two-phase mixture of dextran (DEX) and polyethylene glycol (PEG), which can phase separate into DEX-rich and PEG-rich pha…
Motile bacteria crossing liquid-liquid interfaces
Jiyong Cheon, Joowang Son, Sungbin Lim +5
Real-life bacteria often swim in complex fluids, but our understanding of the interactions between bacteria and complex surroundings is still evolving. In this work, rod-like \text…
