Food Nanotechnology Research Group

FOOD NANOTECHNOLOGY RESEARCH GROUP

The application of nanotechnology to food has considerable potential for both benefit and risk. The research group is interested in the areas of

  • Food safety, quality and integrity
  • Food formulation and structure
  • Toxicology and risk assessment

An example of the work in which the group has extensive expertise is the production and engineering of biomolecular ligands such as antibodies and aptamers. The use of these biomolecules as tools for use in food safety, quality and integrity (fraud) control is an area of active research, especially for the development of biosensors and simple, portable, rapid assays.  Applications include screening for food adulterants, contaminants, pathogens and allergens, as well as confirmation of species identity. These services are also provided commercially to the food industry through the NoWFOOD Centre (www.nowfood.co.uk).

Members of the group can also provide services in areas relating to nanomaterials legislation and its application to food. The assessment of toxic risk from nanomaterials that might be present in food derived from additives or migration from packaging is also an area of active interest, as well as the modelling of fate and behaviour. Members of the group include: 

  • Prof Graham Bonwick (Director)
