“…For instance, while improving sensor selectivity, it is crucial to ensure that an improvement does not compromise sensor sensitivity and stability. In addition, most studies are conducted in laboratory conditions, and the transition to real-world applications demands the consideration of factors such as temperature, humidity, and fluctuations in the ion concentrations [31][32][33][34]. While we face numerous challenges, our primary focus remains on unraveling the mechanisms and patterns underlying the conformational changes in PEG in response to environmental variations.…”

Polyethylene glycol (PEG) is an artificial polymer with good biocompatibility and a low cost, which has a wide range of applications. In this study, the dynamic response of PEG single chains to different ion concentrations was investigated from a microscopic point of view based on single-molecule force spectroscopy, revealing unique interactions that go beyond the traditional sensor-design paradigm. Under low concentrations of potassium chloride, PEG single chains exhibit a gradual reduction in rigidity, while, conversely, high concentrations induce a progressive increase in rigidity. This dichotomy serves as the cornerstone for a profound understanding of PEG conformational dynamics under diverse ion environments. Capitalizing on the remarkable sensitivity of PEG single chains to ion concentration shifts, we introduce innovative sensor-design ideas. Rooted in the adaptive nature of PEG single chains, these sensor designs extend beyond the traditional applications, promising advancements in environmental monitoring, healthcare, and materials science.
