Silica nanoparticles (SNPs) are particles of silica which are in the range of 1 to 100 nm in size. In the present study, native silica nanoparticles (SNPs) have been prepared chemically using cetyltrimethyl ammonium bromide (CTAB) and sodium silicate as precursors. The prepared native SNPs were organically modified using the trioctylphosphine oxide (Cyanex921) to yield the modified CY-SNPs particl...
