Helping a PhD student submit their first paper is one of my favourite things.
Professor Lynch’s team is researching what happens to nanoparticles – tiny particles added to a wide range of everyday products to make them better (lighter, stronger, brighter, water-repellent, dirt-repellent and more) – in the environment.
Nanomaterials have many unique properties that make them useful for a wide range of applications, the main one being that they are very reactive – this also makes them very dynamic – they are constantly transforming and interacting with their surroundings. Understanding these transformations, which can be physical, chemical, or biological, is vital to making sure that products are safe. Her team uses a range of approaches and considers a range of scales of interaction – from the first contact with biomolecules such as proteins, lipids and dissolved organic matter, which adsorb to the nanomaterials surface, changing their surface properties to how nanoparticles interact with cell and organisms, such as the biofilm and the water flea, Daphnia magna. Despite their tiny size, these creatures occupy an important place in the food web and can tell us a lot about how the environment is faring.
Because many of the key biological processes and pathways are similar across species, this can provide information on how nanoparticles might affect other species, including human health. Her team uses this information to feedback into product design, resulting in safer consumer products and to design alternative testing strategies that reduce the need for testing on animals without compromising environmental or human health and safety.
