Fig. 2From: Correction: Mesoporous silica nanoparticle-encapsulated Bifidobacterium attenuates brain Aβ burden and improves olfactory dysfunction of APP/PS1 mice by nasal deliveryEffects of MSNs on the growth of Bifidobacterium. Changes in bacterial growth of a Bifidobacterium and b Escherichia coli (E. coli) in the presence of different MSN concentrations. c Viability of encapsulated Bifidobacterium and E. coli during exposure to simulated intestinal fluid (SIF) with bile salts. d Release of Bifidobacterium and E. coli from MSNs encapsulation in SIF at 37 °C. Viability represents the percentage of bacteria surviving relative to the initial population. Data are presented as mean ± SD, n = 3Back to article page
