GACR project (2020-2022) granted

Thanks to GACR funding, we can for next 3 years focus on project (20-24155S):

Insight in preferential interactions, bridging, and cononsolvency on PNIPAM by experimental and computational thermodynamics

We are looking for enthusiastic students (Bc/MSc/PhD). We are always happy to present the broader frame, discuss more details of this project, and possible topics for theses.

 

Welcome new students

Our group strengthens. Currently we have 5 Master students, and one graduated Intern! We are happy to have you here. Hope to have a lot of fun in tackling the challenges in Soft Matter. Group webpage

Generic ingredients in Hofmeister series

In our recent contribution with Berlin & Freiburg colleagues, we provide a generic evidence on sufficient interaction ingredients between biomolecules and salts (effective B2-interaction and mean field electrostatics) to manifest in the direct, or reverse Hofmeister series. More details can be found in the manuscript.

Arginine ‘Magic’ Established in Accounts

We knew that guanidinium cation is an unique species, which desire our attention. Its ability to form cation-cation pairs is manifested in aqueous solutions of guanidinium salts as well as between arginine sidechains in proteins. Gdm-stackingSuch arginine magic was pointed out to lead to an unexpected attraction between polyarginine chains with consequences to the action of arginine-rich cell penetrating peptides.
