The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《A novel BMSN (biologically synthesized mesoporous silica nanoparticles) material: synthesis using a bacteria-mediated biosurfactant and characterization》.

Mesoporous materials (MMs) have recently been applied as advanced nanomaterials in different fields (separation, catalysis, adsorption etc.). Synthesis of MMs by chem. surfactants is not ecofriendly. This study focused on the biol. synthesis of a MM by sol-gel method, using a Bacillus subtilis BBK006-mediated surfactant (template) and a precursor (TEOS). The biol. synthesized mesoporous silica nanoparticles (BMSN) were formed at calcination temperatures of 450-600 °C. The BMSN comprise Si and O elements with sp. weights of 56.09% and 42.13% resp., where the at.% was detected to be 41.79% and 55.10%, resp. The phase identity of the synthesized particles (61-300 nm uniform spherical shape; surface area: 8.2616 m2 g-1; pore diameter at 550 °C: 14.8516 nm) was confirmed with wide-angle XRD (10°-81°). A typical type IV isotherm was exhibited (BET curves) following IUPAC nomenclature and confirmed the mesoporous nature. The green-synthesized biosurfactant-mediated BMSN is an environmentally promising material to apply in biomedical science (e.g., antimicrobial activity, drug delivery, CMC, anticancer activity) and oil spill management.
