Nanotechnologies are now poised to revolutionize the electronic, chemical and biotechnology industries and biomedical fields. Silica nanoparticles have been prepared in this work using modified Sol- gel method at room temperature that employs a water-soluble amine as catalyst, Tween 80 water as a micelle producer and tetraethylorthosilicate (TEOS) as the silica source. The pH value of the aqueous phase was controlled between 10.3 and 10.5. Silica nanoparticle that has been synthesized using modified Sol- gel process is water soluble in nature. The size of nanosilica particle changed when we change the volume of the solvent, which 1-butanol in this research. The changes of the nanoparticle were gradual according to the solvent volume. But after certain amount of solvent volume, the increment is stopped and the size decreased gradually. This obviously showed that the influence of solvent in formation of Nanoparticle is limited to certain level only. This creates a new way which the manipulation of the size can be done with the help of solvent too. The influence is not as strong as water/ alkoxide ratio and pH of the solution. Further research need to be conducted to study precise influence of the solvent to the size of silica nanoparticle by modified sol-gel process.
