Polydiacetylene (PDA) is a mechanochromic polymer that changes its color or emits fluorescence when force is detected, and is being targeted for practical use as a biosensor to detect biomolecules and other substances. However, sensitivity control is essential for practical use, and the effect of ions on sensitivity is not known. The goal of this study is to clarify the effect of ions (Na, Ca, Mg, etc.) on the force sensitivity of PDA using nano friction force microscopy, a technique unique to Sugihara Laboratory.
