Amino modified mesoporous silica xerogel was biomimetic synthesized (B-AMSX).
Indomethacin (IMC) loading capacity was improved using B-AMSX compared to B-MSX.
B-AMSX and B-MSX enhanced IMC dissolution due to crystalline conversion effect.
IMC released faster from B-AMSX than B-MSX due to larger pore diameter of IMC-AMSX.
