study, we demonstrate the feasibility of spectral multiplexing by SERS using micronsized polystyrene (PS) beads loaded with SERSactive nanoparticles. The silicaencapsulated SERS nanotags comprise gold nanocrystals with a selfassembled monolayer (SAM) of aromatic thiols as Raman reporter molecules for spectral identiﬁcation.

Precipitated silica contains chemically bonded water in the form silanol groups is also removed after 2 hours of ignition time at 1000oC. The ignition loss is determined with the substance that has previously been dried for 2 hours at 105oC. 5. SiO2 content Silicon dioxide content is determined gravimetrically by fuming off with hydrofluoric acid.

To acquire high bonding density, the silica microspheres must first be activated. This typically involves the regeneration of hydroxyl groups through an acid incubation followed by immediate silanization, or drying and later silanization. Acidwashed or derivatized microspheres should be .
The surface modification of silica has been investigated in bulk surfaces and micron size silica beads by many characterization techniques [14–19]. A reaction mechanism was suggested as through the interaction between the amino group of APTES and surface Si–OH group in anhydrous condition [ 14, 20 – 22 ] or through the self catalytic ...
