Characterization of GNPs+iPRF. a. picture showing the injectability of the 20 w/v% GNPs+i-PRF gel; b. 20 w/v% GNPs+i-PRF gel maintained its shape after three days in the water; c. the compression modulus of the 12, 15, 20 w/v% GNPs+i-PRF gel; d. image of the 20 w/v% GNPs+i-PRF gel; e, f. the compressive and recover properties were assessed by placing an iron prop (weighs 78.26 g) on top of the sample and then lifting it up; g. the rabbit whole blood at the very start (Control); h. the coagulation of GNPs+i-PRF mixed with rabbit whole blood; i. the whole blood clotting time of Control, DBBM, DBBM+i-PRF, GNPs and GNPs+i-PRF. Red dotted box indicates the location of the GNPs+i-PRF gel
