About the Project

A PhD studentship is available in the Imaging Concepts Group at Glasgow University, researching advanced multi-photon microscopy. The aim of the project is to develop ways to optically read out voltage sensitive dyes at increased depth in murine hearts.
In the heart, function and structure are intricately related, therefore, to understand the formation of arrhythmias, we need to investigate cellular electrophysiology within its native structural environment. Optical methods based on multiphoton microscopy are ideally suited as they are non-invasive and robust to scattering tissue. This project will develop novel optical technology such as temporal focusing and 3-photon microscopy to investigate electrical activity deep within the wall of the heart chamber to unlock cardiac conduction transmurally in health and disease. The student will develop novel multi-photon tools to optically read out voltage sensitive dyes deep inside the heart: to date, there is no way to measure cardiac electric excitation across the entire depth of the ventricle wall. From a technical point of view the question is whether strategies to extend the imaging depth in ubiquitous 2-photon microscopy are sufficient or whether ultimately only 3-photon excitation will provide the necessary resilience to scattering. The fundamental imaging depth in 2P microscopy is reached when the signal-to-background ratio reaches unity. Temporal focusing disperses the frequency components of the laser pulse by a diffraction grating, recombining them only in the focal plane. This directly shifts the SBR in favour of in-focus fluorescence to achieve deeper imaging. This technique has recently been proposed in deep brain imaging with great potential.
The NHS highlights that 2 million people are affected by abnormal heartbeats, or arrhythmias, in the UK per year. This project will establish a novel perspective in cardiac electrophysiology by developing disruptive optical technology with wide applicability in the study of a global health issue.
