Postdoctoral Research Fellow
Job description
Project Single-molecule in vivo biosensor based on microlasers
Faculty of Environment, Science and Economy
This new full time post is available immediately on a fixed term basis until 31 October 2024.
Summary of the role
The Faculty wishes to recruit a Postdoctoral Research Fellow to participate in developing a single molecule in vivo biosensor.
We are seeking a highly motivated and talented Postdoctoral Researcher to join our interdisciplinary team at the University of Exeter, Laboratory of Prof Vollmer, see vollmerlab.com.
The successful candidate will lead a pioneering research project focused on the development of single molecule in vivo biosensors based on whispering gallery modes (WGMs). This project presents an exciting opportunity to advance the frontier of biosensing technology and make significant contributions to the fields of biophotonics, molecular biology, and biomedical engineering.
Background : Whispering gallery mode (WGM) resonators are a class of optical microresonators renowned for their ability to confine light waves within whispering gallery-like trajectories along the circumference of a circular or spherical cavity. These resonators exhibit exceptionally high quality (Q) factors, enabling prolonged photon lifetime and ultra-sensitive detection of minute changes in the surrounding environment. Over the years, WGM resonators have found diverse applications in optical sensing, spectroscopy, and telecommunications.
In recent years, there has been growing interest in leveraging the unique properties of WGM resonators for the development of single molecule biosensors. By functionalizing the resonator surface with specific biomolecular receptors, such as antibodies or aptamers, WGM biosensors can detect and quantify individual biomolecules with unprecedented sensitivity and specificity. This capability holds immense potential for elucidating fundamental biological processes, studying molecular interactions, and diagnosing diseases at the single molecule level.
Despite significant progress in the field of WGM biosensing, several challenges remain, particularly in extending these techniques to in vivo applications.
The job : In this context, the postdoctoral position aims to address the critical need for developing single molecule in vivo biosensors based on whispering gallery modes of microlasers. The successful candidate will play a pivotal role in advancing the frontier of WGM biosensing technology and overcoming the barriers to in vivo molecular detection. By integrating expertise in photonics, molecular biology, and biomedical engineering, the postdoctoral researcher will lead groundbreaking research efforts aimed at designing, fabricating, and characterizing WGM microlaser biosensors tailored for in vivo applications.
Responsibilities:
Design and fabricate whispering gallery mode (WGM) biosensors capable of detecting and characterizing single molecules in living systems. WGM biosensors will be based on microlasers, see the relevant section of this perspective article: https: // pubs.acs.org/doi/full/10.1021/acsphotonics.3c01570
Develop innovative experimental methodologies for in vivo imaging and sensing of biomolecular interactions and dynamics at the single molecule level using WGM microlasers.
Conduct rigorous experimental studies to validate the performance, sensitivity, and specificity of the developed biosensors in biological samples and complex environments.
This EPSRC-funded post is available immediately to 31 October 2024. The successful applicant will fabricate microlaser sensors based on microbeads and customise optical platform to image the sensors and acquire the optical spectrum which contains information on molecule detection. Applicant will characterise the sensing performance and apply these sensors for in vivo sensing applications working together with biologists.
