Job description

We are looking for an enthusiastic PhD candidate who will investigate the exploitation of oleosomes as natural carriers of hydrophobic pharmaceuticals for oral administration. The PhD candidate should have an affinity for soft matter science and be motivated to apply this knowledge on natural materials. Furthermore, the student should be curious in understanding the molecular interactions in oleosome membranes and enthusiastic to exploit nature in order to design biobased functional materials.

The PhD candidate should have an independent attitude and an inherent interest in fundamental research that can lead to new applications.

Information on Objectives for this PhD vacancy
Oleosomes are natural oil droplets stabilised by a phospholipid/protein membrane and can be extracted from seeds or nuts. They have a hydrophobic core and a hydrophilic surface and can potentially replace the engineered oil droplets. Additionally, the high permeability of their membrane makes oleosomes excellent absorbents and carriers of hydrophobic molecules sensitive to oxidation and hydrolysis. Currently, synthetic carriers are being used to protect pharmaceuticals during oral administration, however, their biocompatibility is controversial. On the other hand, oleosomes could be an excellent alternative to create biobased and fully biocompatible carriers.

Using of oleosomes as carriers require the investigation of their membrane at a molecular level. For this, advanced analytical techniques have to be used and developed. Oleosomes will be extracted from seeds and their membrane will be characterized for its molecular composition and elasticity. Moreover, the permeability of the oleosome membrane to hydrophobic molecules will be investigated and the fate of hydrophobic molecules during storage will be tracked. The oleosome membrane structure will also be modified in order to adjust its properties according to the needs. Confocal microscopy, transition electron microscopy, atomic force microscopy, light scattering, DSC, GC, and LC-MS will be employed for this research project.
