在PLCL和PGD表面观察到许多绿色荧光，表明血小板激活情况严重。该结果与SEM观察的结果一致。这说明带正电荷的PDA涂层可诱导血小板粘附和活化。相反地，在PGD-ACH₁₁和PGD-CAG/ACH₁₁表面P-选择素的表达量明显降低，意味着少量的血小板聚集和血凝块形成，这主要得益于ACH₁₁肽的抗血小板粘附和活化特性。

Much green fluorescence was observed on the PLCL and PGD surfaces, indicating serious platelets activation. This result was consistent with the results of SEM observation. It was reported that PDA layer with positive charge can induce the platelets adhesion and activation. Importantly, on the PGD-ACH₁₁ and PGD-CAG/ACH₁₁ surfaces, a significantly decreased amount of P-selectin expression indicated less platelet aggregation and clot formation, mainly for the presence of ACH₁₁ peptide with reported anti-platelets adhesion and activation property.
