Background: Plasma perfusion was widely used to clear toxic substances of plasma. Particle size and uniformity of adsorbent microspheres also affect the absorption rate., Methods: Conventional suspension polymerization was improved using a pre-dispersion homogenizer to obtain novel adsorbent microspheres, named ERM-0100. Microsphere-related characteristics and attributes were analysed., Result: The ERM-0100 microspheres efficiently adsorbed different bilirubin concentrations, with a maximum rate of 59.72 ± 1.08%. At high bilirubin concentrations, ERM-0100 exhibited similar adsorption rate with BRS350 and BS330 (p = 0.303, p = 1.000, relatively), and higher than HB-H-6 (p = 0.000). At different concentration, ERM-0100 showed good adsorption performance. The ERM-0100 had no significant adsorption for electrolyte; for TP and ALB, the loss rates of ERM-0100 were 15.65 ± 0.36 and 23.23 ± 1.11%, respectively. In addition, ERM-0100 showed good blood compatibility., Conclusion: The ERM-0100 is a potential biomedical material for plasma perfusion for good effect, less costs and more safety. The microspheres may be coated to reduce its protein adsorption., (© 2016 S. Karger AG, Basel.)
