A process for delivery of a first ionic molecule into a subterranean formation comprising:
- supplying a particle carrier system, the particle carrier system including a particle carrier, the particle carrier being nano- or micro-sized, the particle carrier having a surface, the surface including a first ionic functional group, the first ionic functional group chemically bound to the first ionic molecule;
- injecting the particle carrier system into the subterranean formation;
- and
- altering the pKa in the subterranean formation to a first release pKa to release the chemical bond between the first ionic functional group and the first ionic molecule.
