General description

Composition of nanoparticles non-crystalline colloidal SiO2 particles
Dispersion loading and medium (27 ± 3) wt.-% in water
Particle size d90 (volume distribution; DLS) < 50 nm
pH 2 ± 1
Density (1.2 ± 0.1) g/l
Primary particle size < 20 nm
Surface modification using Triethoxylpropylaminosilane

Application

Silica nanoparticles play a crucial role in biotechnology including bone engineering and drug delivery. The amino functionality present on the surface of these materials provide a synthetic handle for further modification and conjugation to target moieties. Amino functionalized silica particles can be used for applicaitons including in vivo gene delivery, nanocomposite formation, and formation of biofilms.
