a Illustrated working principle for generating electrospun nanoyarns; b SEM images of nanoyarn scaffold with similar surface morphology among different groups; c Frequency distribution chart of individual fiber diameters and the angles between adjacent yarns; d Processes of water droplet spreading on scaffold surface recorded before, 0 s and 30 s after water-material contact; e Quantitative measurement of water contact angles at 30 s; f FTIR spectra of different scaffolds, and COL1 and Fmod revealed overlapped characteristic absorption peaks of C = O bond, amid I group and amid II group; g XPS assay to show the dose-dependent increasing proportion of nitrogen on the surface of nanoyarns; h Histogram illustration of mechanical properties of different nanoyarn scaffolds. All error bars indicate standard deviation. *p < 0.05, **p < 0.01, ***p < 0.001.
