a Sankey paradigm showing different substrates binding activity of various CBMs. The thickness of the line indicating the level of affinity. b Structural pre-inspection effect of FTSM-CBM-1 on chitosan hydrogel. Left, scheme of chitosan hydrogel and its networked microstructure. Right, FRET/donor ratiometric images showing stress distribution of chitosan hydrogels indicated by FTSM-CBM-1. The measurements were carried out in triplicate. c Visualized stress distribution of cellulose-based biomaterials via FTSM-CBM-2. Left, the molecular structure of FTSM-CBM-2. Right, confocal fluorescence and FRET/donor ratiometric images of fibrous hydrogels in the tensile (top) and bending (bottom) states. The measurements were carried out in triplicate. LUT showing the distribution of stress calc. White scale bars, 200 μm. Green scale bars, 500 μm.
