Fig. 3: Effect of specific surface area and surface hydroxyl content of AlOOH nanorods on antigen adsorption.

A TEM analysis and B XRD patterns of the AlOOH-R1 after calcination. AlOOH-R1-cal was obtained by treating AlOOH nanorods at 350 °C for 1 h. The scale bar is 100 nm. Adsorption isotherms of C HBsAg, D OVA, and E BSA by AlOOH-R1 and AlOOH-R1-cal in MOPS buffer at pH 7.4.
