Surface conjugated diamagnetic Chemical Exchange Saturation Transfer (diaCEST) agent carriers and methods of making and using are described herein. The particles are safe alternatives to conventional paramagnetic or superparamagnetic metal-based MRI contrast agents that are often toxic and therefore not biocompatible. The carriers described herein can provide simultaneous monitoring of multiple particle types labeled with 'multicolor' diaCEST contrast agents. In some embodiments, the carriers are micro- and/or nanoparticles. In other embodiments, the carriers are liposomes. In some embodiments, the particles and/or liposomes are mucus penetrating. In other embodiments, the particles and/or liposomes are not mucus penetrating.
