The Rosalind Franklin Institute (the Franklin) is a national research centre, funded by the UK government through UK Research and Innovation, dedicated to bringing about transformative changes in life science through interdisciplinary research and technology. The Biological Mass Spectrometry Theme focuses on the development of new instrumentation for mass spectrometric imaging (MSI) allowing the visualisation of molecular distributions at subcellular level and the de-novo structure elucidation of chemical species detected by MSI techniques. The ultimate goal of the Theme is to understand the working mechanism of molecular interaction networks in health and disease and define novel diagnostic and prognostic targets for next generation healthcare.
The project will focus on the development of a novel ion source and atmospheric interface design and the design of associated laser optics. The envisioned instrument will have atmospheric pressure/ambient imaging module using desorption electrospray ionization (DESI), AP-laser desorption ionization (AP-LDI) and combination thereof. In addition to the primary desorption ionization methods, the ion source will feature low-temperature plasma and excimer lamp post-ionization capabilities. The atmospheric interface will comprise a heated metal capillary, an impact declustering surface and a ring electrode ion guide element (\xe2\x80\x9cion funnel\xe2\x80\x9d). The postholder\xe2\x80\x99s primary focus will be the implementation of mid-infrared, femtosecond-picosecond resonant frequency laser desorption capability in addition to the modalities listed above. The actual work includes the construction of laser source, modalities for post-desorption ionisation and collecting the ions at atmospheric pressure for mass analysis.
The project will be hosted by the Rosalind Franklin Institute facilities at Harwell but will involve strong collaborative activities with Dr Robbie Murray\xe2\x80\x99s research group at Imperial. The project will also involve extensive collaboration with scientists at the National Physical Laboratories (NPL) and Bruker Corporation. The post reports to the Franklin\'s Theme Lead for Biological Mass Spectrometry, Professor Zoltan Takats and will also work with MS leads of the Franklin\xe2\x80\x99s Member Institutions.
