Abstract
A process for forming a particle carrier system includes supplying a particle carrier, the particle carrier having a surface and modifying the particle carrier surface to include a first ionic functional group. The process also includes chemically binding the first ionic functional group on the particle carrier surface to a first ionic molecule.
Claims7
A process for forming a particle carrier system comprising:
- supplying a particle carrier, the particle carrier having a surface, wherein the particle carrier is mesoporous, the particle carrier having pore sizes between 2 and 50 nm;
- modifying the particle carrier surface to include a first ionic functional group;
- modifying the pores of the particle carrier to include a second ionic functional group;
- chemically binding the first ionic functional group on the particle carrier surface to a first ionic molecule;
- and binding a second ionic molecule to the pores of the particle carrier.
