MRI contrast agent delivery using spore capsules: controlled release in blood plasma

Chem Commun (Camb). 2009 Nov 14:(42):6442-4. doi: 10.1039/b909551a. Epub 2009 Oct 1.

Abstract

The exine coatings of spores can be used to encapsulate drug molecules. We have demonstrated that these microcapsules can be filled with a commercial gadolinium(III) MRI contrast agent (in this proof of concept study Gd-DTPA-BMA was used) which is slowly released in plasma due to enzymatic digestion of the capsule.
