We offer silica nanoparticles of the highest quality that you can possibly find in today’s market. The size variation and batch-to-batch repeatability are the key advantanage of our silica nanospheres. The largest variation of our silica nanospheres from different batches is precisely controlled within a CV value of 3%. Different functional groups can be added on the silica surfaces, such as thiol groups (-SH), amine groups (-NH2), hydrophobic groups (-CH3), and others, which are suitable for various applications in different research and development fields.
