Molecular delivery

Module Title - Molecular delivery
Number of credits – 10

Module description

This module defines and explains the principles of molecular delivery that underpin formulation engineering in food, pharmaceutical and speciality chemical processing. The first part of the module outlines the engineering science of diffusion and molecular transport, in terms of Fickian and non-Fickian diffusion and mass transfer models. The emphasis is on the physical factors that give rise to each type of diffusional and transport process and how they can be represented physically and mathematically.

In the second part of the module, the ways in which this type of approach can be applied practically will be outlined using a series of examples and case studies e.g. encapsulation in drug delivery, consecutive mass transfer and diffusion stages in flavour delivery, and transport processes in catalysis and fuel cells.

By the end of the module you will be able to:

  • Describe the fundamental engineering science and physics which determine how molecules move in processes and in structured materials.
  • Express the processes of molecular delivery in terms of a set of mathematical relationships which quantify the physical processes taking place at the molecular length stage.
  • Describe and demonstrate now these mathematical techniques can be used to quantify the ways in which formulated products work and are designed.
  • Apply the above to relevant industrial problems.
