There
are different tests and experiments which are done these days at different
laboratories. In order to conduct these tests and experiments in the safest
possible manner and to receive accurate outcome, we have to use the right kind
of materials, vessels and other equipments. When it comes to the use of the
aqueous solutions, the use of the iron
oxide beads coated with silica is must. While using this, the
overall stability of the magnetic NPs can be enhanced and this is very
necessary. This type of coated silica also creates a scaffold that is very
handy for different functional sections.

- Different methods are followed to
prepare them
These
silica coated beads can be prepared while following different methods. However,
it’s the Stober process that is mostly preferred to produce this type of coated
silica beads. While seeding a proper mixture of water and ethanol and while
adding the catalyst like iron oxide and by adding the silica precursor, these
coated silica beads are produced. Silica coating for the nano particles has
become very vital these days. As silica is a photochemically stable material,
chemically inert and transparent, while coating it on the iron oxide beads,
proper micro particles can be formed. This helps to arrange or organize the
plasmonic nano particles in a proper harmony in the periodic structures.
- Silica is everywhere
Amine-terminated magnetic silica beads are also in demand these days. Silica is the
material that is chemically inert and transparent and that’s why it is used to
coat the nano particles these days. Now you can avail these nano particles
online in affordable price and use them for different applications.
