Three blood samples of known types were acquired and stored in Vacutainer test tubes containing lithium-heparin anticoagulant from Zhongda Hospital in Nanjing, China. This protocol was approved by the institution’s Ethics Committee according to the provisions of the Declaration of Helsinki regarding investigation in humans. Three kinds of antibody solutions were also added with lithium-heparin anticoagulant in the experiments. The amount of the mixed blood samples was kept the same for testing. The porous graphene film was infused with the mixture of solidifiable paraffin and the liquid paraffin at the volume ratio of 1:1 in this section. The blood plasma was removed from the blood samples.
