Blood compatibility evaluation: a platelet adhesion assay: platelet-rich plasma (PRP) incubated with nothing as the negative control. At the same time, the PRP incubated with the glass powder was a positive control. b Hemolysis assay: 2% red blood cell suspension was incubated with PBS, GPRPP-Y8U@P (1, 0.5, 0.25, 0.125 mg/mL), and 0.1% Triton-100. c Pictures of plasma recalcification time assay. Pictures of plasma with corresponding processing (upper). Pictures of plasma solidification (underside). d Blood clotting time: the time of sample solidification was recorded as PRT. Asterisks indicate significantly differences (*P < 0.01, **P < 0.001, ***P < 0.0001)
