Cooperation and competition of basepairing and electrostatic interactions in mixtures of DNA nanostars and polylysine
Gabrielle R. Abraham, Tianhao Li, Anna Nguyen +2
Phase separation in biomolecular mixtures can result from multiple physical interactions, which may act either complementarily or antagonistically. In the case of protein-nucleic a…

Condensation and activator/repressor control of a transcription-regulated biomolecular liquid
Sam Wilken, Gabrielle R. Abraham, Omar A. Saleh
Cells operate in part by compartmentalizing chemical reactions. For example, recent work has shown that chromatin, the material that contains the cell's genome, can auto-regulate i…

Controlling the size and adhesion of DNA droplets using surface-active DNA molecules
Daqian Gao, Sam Wilken, Anna Nguyen +3
Liquid droplets of biomolecules serve as organizers of the cellular interior and are of interest in biosensing and biomaterials applications. Here, we investigate means to tune the…
