Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Biophysics Summary: Results: TEM shows that all MSNs samples are spherical in shape. The size of MSNs is found to increase with the increase in NH4OH. AFM is successful in providing 3D images and surface area of all samples. Pore volume of MSNs is found to decrease with increase in size as determined from N2- isotherm using Barrett-Joyner- Halenda (BJH) method.The encapsulation efficiency is found to decrease as the size of MSNs increases due to a decrease in pore volume. Conclusion: Preparation of MSNs with different properties (size, surface area and pore volume) is feasible and would probably affect their capability as nanocarriers and would also allow the use of MSNs in various biological and medical applications
