a–c Optical images (a), viscoelasticity comparison (b), and FT-IR spectra (c) of CNT, SF, PLA and SCP mixture. SCP, SF/CNT/PLA mixture; CNT, carboxylated carbon nanotubes; PLA, polylactic acid; SF, silk fibroin. d Schematic illustration of the preparing monolithic biosensing yarn through wet spinning technique. Inset, a continuously prepared monolithic biosensing yarn. Scale bar, 1 cm. e Stress–strain curves of the SCP and CSCP yarns. CSCP, core-sheath SCP. f Specific surface area of silk yarn, conventional coated silk yarn, and CSCP yarn (n = 3 independent yarns). Data are presented as mean values + /− SEM. g SEM images of CSCP yarn. Scale bars, 200 μm in main image and 1 μm in inset image.
