Stability enhancement and injectability of MCG. a G′ and G′′ versus frequency and b G′ and G′′ on strain amplitude sweep for CG, and MCG at 25 °C. c G′ and G′′ for CG and MCG with alternating shear strains of low (1%)—high (500%)—low (1%) strain at the frequency of 1 Hz. d Schematic diagram of CG and MCG microstructure comparison. e The homemade injection device. f The digital images of needles with different sizes. g The injection force of MCG (10 w/v %) with different needles. h The injection force of MCG (10 w/v %) in the first minute with different needles
