Abstract
A light-emitting marker particle having a light-emitting particle core containing a light-emitting material and first and second surface groups bound to the light-emitting particle core. The first surface group contains a polar group and is an inert group which does not bind to a biomolecule. The second surface group contains a biomolecule binding group.
Claims20
A light-emitting marker particle comprising a light-emitting particle core, first surface groups bound to the light-emitting particle core and second surface groups bound to the light-emitting particle core, wherein:
- the light-emitting particle core comprises a light-emitting polymer;
- the first surface group comprises a polar group;
- the first surface group is inert;
- the second surface group comprises a biomolecule binding group;
- and a number of moles of the second surface group is less than 10% of a total number of moles of the first and second surface groups.
