silica

Magnetic and fluorescent silica particles (sicastar®-M-CT-F)
 

combine separation and detection purposes,
can be separated also in highly viscous media with conventional permanent magnets,
show a homogeneous distribution of magnetite and covalently bound fluorescence dye in the silica matrix by the special preparation method,
are available with red fluorescence (sicastar®-M-CT-redF, excitation: 569 nm, emission: 585 nm) and green fluorescence (sicastar®-M-CT-greenF, excitation: 485 nm, emission: 510 nm),
consist of cluster-typed aggregates in the size range of 3 – 10 µm with a mean diameter of 6 microns,
are extremely stable in organic solvents and at high temperatures,
are available with a plain surface (Si-OH) or with NH2 or COOH groups on the particle surface.
