Abstract

The talk covered the extraction of sporopollenin exines which are the shells of pollens and spores. An outline was given relating to some of the physical and chemical properties of sporopollenin exines, in particular their physical and chemical resilience and their uniformity. Mention was made of their ability to act as microcapsules and their potential to be applied to drug deliver. Also discussed are results indicating the antioxidant properties of pollen extracts. Evidence was given to show how sporopollenin exines have been used as imaging agents in Magnetic Resonance Imaging. Finally some basic chemistry and modifications of sporopollenin was discussed indicating potential applications in such as drug delivery, solid supported synthesis and ion exchange chromatography.(More information can be found on (www.sporomex.co.uk)
