Figure 13. Platelet adhesion assay.
(A-C) SEM images (2000x and 5000x magnification) show the greatest number of platelets adhering to POSS-PCU surfaces. (A) POSS-PCU, (B) POSS-PCU-FS, (C) POSS-PCU-FS+CD34. (D) The degree of platelet adhesion, expressed as the Platelet Adhesion Index, was significantly reduced by incorporation of FS and subsequent conjugation of anti-CD34 antibodies. *denotes a significant difference (p < 0.05).
POSS-PCU-FS: POSS-PCU with fumed silica anchors, POSS-PCU-FS+CD34: POSS-PCU biofunctionalized with anti-CD34 antibodies.
