Fig. 1From: Layered double hydroxide nanoparticles as an adjuvant for inactivated foot-and-mouth disease vaccine in pigsElectron micrograph of LDHs and adsorption capacity of LDHs. a Particle size distributions of LDHs with single peak. b Representative scanning electron microscope image of LDHs. c Absorption of FMDV to LDHs. The X-axis represents the amount of inactivated FMDV in different tubes. The Y-axis values is the A280, which represents the amount of unbound FMDV 146S particle after adsorption with LDHs. Data are expressed as mean ± standard error of the mean (n = 2)Back to article page
