Postdoctoral Researcher in development of plasmonic nanopore for single molecule sequencing by surface enhanced Raman spectroscopy (SERS)

Applications are invited for a full-time

Postdoctoral Researcher in development of plasmonic nanopore for single molecule sequencing by surface enhanced Raman spectroscopy (SERS)

position under supervision by Assistant Professor Jian-An Huang who has strong expertise in single-molecule SERS analysis of biomolecules and plasmonic nanopore fabrication in the Research Unit of Health Science and Technology, Faculty of Medicine at University of Oulu, Finland.

Project description

The postdoctoral researcher will work in the EIC Pathfinder OPEN project:  “Plasmonic nanopore technologies for automatic manipulation and Raman spectroscopic sequencing of single proteins (RamanProSeq)” that aims to develop Raman spectroscopic single-molecule protein sequencing technology capable of reading protein primary sequence at single-amino-acid resolution by integrating plasmonic nanopores with a high-speed Raman detection system, an automated control system, computer simulations, and advanced Raman-based bioinformatics. 

The RamanProSeq consortium includes Prof. Shuai Li in University of Oulu (Finland), Dr. Francesco De Angelis in Italian Institute of Technology (Italy), Dr. Cuifeng Ying in the Nottingham Trent University (UK), Dr. James Yates in Universidade NOVA de Lisboa (Portugal), Dr. Lu Cheng in University of Eastern Finland (Finland) and Prof. Maria Fyte in RWTH Aachen University (Germany) who are leading experts in intelligent automation, ultrafast SERS spectroscopy, nanopore fabrication and engineering, single molecule biochemistry and biophysics, computational biotechnology and AI bioinformatics. Assistant professor Jianan Huang will be the supervisor for fabrication, development and Raman spectroscopic measurement of plasmonic nanopores on nanopipettes in this call and get support from all the partners. 

Description of the position

The tasks of the postdoctoral researcher will be fabrication and characterization of plasmonic nanopore on glass nanopipettes as well as measurement of ion currents and Raman spectroscopy of the biomolecules (DNA, peptides, proteins) in the nanopores such as:

• Design and fabricate glass nanopipettes and characterise them by biomolecule translocation;
• Design, fabricate and characterize plasmonic nanopores on the nanopipettes with low electric noise;
• Measurement and preliminary analysis of ion current and Raman spectra of biomolecules in the device;
• The work duties may include teaching with no more than 10% of working time.

The nanopore fabrications can be firstly based on published protocols and then improved to fit the needs of the project. The biomolecule design, molecule-nanopore interfaces, automatic control of molecule translocation in the nanopore and deep data analysis will be handled by other researchers, discussed and solved together in the consortium.

You will work together with our multidiciplinary team, and have access to the state-of-the-art micro- and nanofabrication and characterization facilities, and biological facilities.
