The effect of developed scaffolds based on collagen modified with caffeic acid (CA), ferulic acid (FA), and gallic acid (GA) on cytocompatibility of hFOB 1.19 cells (expressed by MTT proliferation and lactate dehydrogenase release) after 72 h of culture and hemocompatibility of human erythrocytes (expressed hemolysis rate and lactate dehydrogenase release) after 24 h exposure to materials (n = 4, data are expressed as the mean ± SD,*significantly different from the respective controls (p < 0.05)).
