Viability of plant spore exine capsules for microencapsulation (2010)
Journal Article
Barrier, S., Diego-Taboada, A., Thomasson, M. J., Pointon, J. C., Wadhawan, J. D., Beckett, S. T., …Wadhawan, J. (2011). Viability of plant spore exine capsules for microencapsulation. Journal of materials chemistry, 21(4), (975-981). doi:10.1039/c0jm02246b. ISSN 0959-9428

Sporopollenin exine capsules (SECs) (outer exoskeletal wall of the spores of Lycopodium clavatum) were extracted and examined for their potential use as microcapsules. They were shown, by laser scanning confocal microscopy (LSCM), to be void of their... Read More

Electrochemistry and charge transport in sporopollenin particle arrays (2010)
Journal Article
Thomasson, M. J., Baldwin, D. J., Diego-Taboada, A., Atkin, S. L., Mackenzie, G., & Wadhawan, J. D. (2010). Electrochemistry and charge transport in sporopollenin particle arrays. Electrochemistry communications, 12(10), (1428-1431). doi:10.1016/j.elecom.2010.07.038. ISSN 1388-2481

Electrochemical oxidation of hollow sporopollenin particles immobilised on an electrode surface is investigated in aqueous acidic solution. Redox activity is demonstrated to occur via a mixture of 2e(-)-2H(+) and 2e(-)-1H(+) processes, likely due to... Read More

Enhanced bioavailability of eicosapentaenoic acid from fish oil after encapsulation within plant spore exines as microcapsules (2010)
Journal Article
Bell, J. G., Wakil, A., Mackenzie, G., Atkin, S. L., & Diego-Taboada, A. (2010). Enhanced bioavailability of eicosapentaenoic acid from fish oil after encapsulation within plant spore exines as microcapsules. Lipids, 45(7), 645-649. doi:10.1007/s11745-010-3427-y

Benefits of eicosapentaenoic acid (EPA) can be enhanced by raising their bioavailability through microencapsulation. Pollen can be emptied to form hollow shells, known as exines, and then used to encapsulate material, such as oils in a dry powder for... Read More

MRI contrast agent delivery using spore capsules: controlled release in blood plasma (2009)
Journal Article
Lorch, M., Thomasson, M. J., Diego-Taboada, A., Barrier, S., Atkin, S. L., Mackenzie, G., & Archibald, S. J. (2009). MRI contrast agent delivery using spore capsules: controlled release in blood plasma. Chemical communications : Chem comm / the Royal Society of Chemistry, (6442-6444). doi:10.1039/b909551a. ISSN 1359-7345

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 sl... Read More
