Understanding the intricate interplay between ions and polymers holds key implications for a myriad of fields, from biomedicine to materials science. Here, we present a comprehensive investigation of ion-specific effects on the behavior of single polyethylene glycol (PEG) chains, a versatile polymer widely used in various applications. Employing single-molecule force spectroscopy (SMFS) and quartz crystal microbalance with dissipation (QCM-D) techniques, we systematically explore the impact of different monovalent cations on structural and hydration dynamics of PEG, Surprisingly, our results d...
