Detection of Alzheimer's Disease using Light-Based Technologies
Event details
School of Physics, Engineering and Technology Webinar Series
A team of researchers from the UK and Brazil have demonstrated the simultaneous detection of two critical biomarkers of Alzheimer’s disease in human blood. Their new handheld biosensor - which uses visible light to detect them - can be made using low cost components and is able to detect these biomarkers at clinically relevant levels, opening the door to a simple blood test for disease. Dr Quinn will showcase this exciting result, explain how a novel photonic crystal can be used for biosensing, discuss how the technology outperforms competing tools and highlight recent breakthrough results that have amplified the signal strength.
About the speaker
Dr Steven Quinn obtained an MPhys in Physics from the University of St. Andrews (2009) and an MSc in Radiation, Oncology and Biology from the University of Oxford (2010). After his PhD (St Andrews, 2013) and a postdoctoral position at the University of Glasgow (2013-2016), he took up a Lindemann Trust Fellowship at the Massachusetts Institute of Technology (2016-2017). In 2017, he was appointed to a Lectureship at the University of York and was awarded an Alzheimer’s Research UK Fellowship in 2019. Steven is now a Senior Lecturer, and his group uses a variety of analytical, biosensing and single-molecule techniques to detect and interrogate the structure and dynamics of biomolecules implicated in dementia.
