You are synthesizing MSNPs using CTAB as the surfactant template and TEOS as the silica source. You decide to add a small amount of a hydrophobic swelling agent (like TMB) to the reaction mixture while keeping all other parameters constant. What changes would you most likely observe in the final MSNPs' properties compared to MSNPs made without the swelling agent?

Question

You are synthesizing MSNPs using CTAB as the surfactant template and TEOS as the silica source. You decide to add a small amount of a hydrophobic swelling agent (like TMB) to the reaction mixture while keeping all other parameters constant. What changes would you  most likely  observe in the final MSNPs' properties compared to MSNPs made without the swelling agent?

Answer

The pores will become disordered and lose their hexagonal arrangement, resulting in a Type II isotherm instead of Type IV.

Answer

The average pore diameter will increase, and the specific surface area (BET) will likely decrease or stay roughly similar.

Answer

The average pore diameter will decrease, and the specific surface area (BET) will significantly increase.

Answer

The overall nanoparticle size (measured by DLS) will significantly increase, but the pore diameter will remain unchanged.
