Dr. Sophie Marie Briffa read for a BSc (Hons.) in Chemistry with Materials (2011) and an MSc in Mechanical Engineering (2013), at the University of Malta. In 2017 she was awarded a PhD in Environmental Health Risk from the University of Birmingham (UoB). Her PhD thesis, titled “Synthesis and Ageing Transformations of Manufactured Metal Oxide Nanomaterials” received the Sir Oliver Lodge Prize (2017) for its high quality. The work focused on developing a nanomaterial library of comparably sized PVP capped metal oxide nanomaterials with different metal oxide cores for the purposes of nanosafety studies and looked into the effect of different ageing processes. Sophie has authored a number of peer-reviewed articles and has participated in several international conferences with numerous presentations. She is currently working as a research fellow in the Environmental Nanoscience research group at the UoB working on the H2020 funded project ACEnano and focusing on analytical and characterisation excellence in nanomaterial risk assessment. Her research interests include NM synthesis and characterisation, NM behaviour and transformations in the environment, nanosafety and eco-toxicity of nanomaterials.  In addition to her research, Sophie is passionate about the performing arts, she is a classically trained pianist and runs Hagley School of Dance. She is a qualified ballet teacher holding a Certificate in Ballet Teaching Studies from the Royal Academy of Dance (RAD) and a BA in dance education from the RAD in conjunction with the University of Bath. Her dissertation was awarded the Philip Nind Award for its outstanding quality.   

Collection Overview

The number of manufactured nanomaterials (MNMs) entering the market in everyday products is continuously increasing. These products range from health care to electronics, cosmetics and foodstuff. This increased use of MNMs results in greater environmental release and the potential long-term environmental impact of MNMs still remains poorly understood. As a result, concerns regarding the exposure to humans and other organisms arise. To ensure the safe advancement of market available nano-enabled products, a strong legislative framework is required. However, one of the major difficulties for developing this legislative framework is the ability to obtain reliable and reproducible characterisation information about the MNMs and their behaviour. This information is vital in order to simplify and facilitate hazard and exposure descriptions and allow for the development of a MNM grouping framework. Obtaining this information requires skillful and exceptionally knowledgeable operators who are familiar with the entire panoply of techniques available. These techniques include DLS, UV-VIS, ICP-OES, NTA and BET, among many others. Indeed, even “simple” characterisation of inter-laboratory comparisons produce astonishingly inconsistent data amongst participants. The main difficulty encountered producing these inconsistencies is ambiguity in method interpretation between instrument operators. Consequently, this methods collection series invites researchers with well-established standard operating procedures for analytical characterisation methodologies to submit their method focused contributions to help reduce method interpretation ambiguity and increase standardisation between operators and laboratories.
