I am researching the mechanisms of Silica NP synthesis and methods to further reduce their size and dispersity in size. It can be mesoporous, fumed, or any other structure. A mention of the type and a citation would help tremendously. Thanks!
I think less than 4nm are also reported, specially composites with silica. Here in this paper they reported sub nano (
Photoluminescent silica quantum dots.. around 1-2 nm..
