OverviewAdvanced manufacturing (D Markl), Drug Delivery (Health and Wellbeing – Z Rattray)
We encourage highly-competitive and motivated students with an interest in the pharmaceutical industry and a background in chemical engineering or pharmaceutical sciences to apply for this project
Particles are key components in most drug products ranging from oral solid dosage forms (e.g. tablets and capsules) to controlled release suspension formulations for subcutaneous delivery. Safety and efficacy of these delivery systems are guided by the physical and chemical properties of the particles composing the drug product. The link between the particle properties and its dissolution characteristics is currently poorly understood due to the lack of measurement techniques and models that can capture the fundamental processes involved in the dissolution of particles used for drug delivery. These processes include the absorption of the body fluid which initiates the swelling or erosion of the particle and eventually causes the release of the drug from the particle matrix.
In this project you will be developing mechanistic models of the liquid uptake, swelling/erosion and dissolution of pharmaceutical particles including polymer-based microspheres, granules and agglomerates. The models will be optimised and validated using experimental methods that are capable of in-situ monitoring particle dissolution and its underlying mechanisms such as liquid uptake and swelling/erosion.
