  • PhD - Individual Supervisor
  • Field of Research

  • Mathematics / Natural Sciences
  • Subjects Molecular Biophysics Description A PhD position is available to work at the department Molecular Biophysics at Leipzig University under the supervision of Prof. Dr. Ralf Seidel on hollow DNA-based hybrid nanostructures for optimized optical sensing. This experimental PhD project is part of the Marie Skłodowska-Curie Doctoral Networks HORIZON-MSCA-DN-2021 project called DYNAMO.

    Description of the PhD project

    Objectives: Aim of this project is the development of hollow DNA-based hybrid nanostructures for optimized optical sensing applications (SERS, fluorescence spectroscopy) and analyte molecule trapping/manipulation. Advanced spectroscopy based on surface enhanced EM fields requires metallic nanostructures that support strong localized field enhancement together with specific placement of analyte molecules. With the help of the recently developed DNA-based construction kit complex metal nanostructures with localized strong field enhancement shall be synthesized and their performance characterized in sensing applications in order to find optimal designs.

    Expected Results: Tailored hollow metal nanostructures with specific presentation of analyte molecules exhibiting an improved performance in optical sensing applications. Robust methodology to fabricate nanopores for hybrid sensing applications.

    Planned Secondments: To design and test suitable hollow hybrid nanostructures for SERS, the candidate will visit HU Berlin for 3 months during year one. To get insight into hybrid nanopore assembly, the candidate will visit Cambridge University for 2 months in year two. To integrate fabricated hollow hybrid nanostructures with solid state nanopores, the candidate will visit the Italian Institute of Technology for 3 months in year three. Depending on the project progress there will be additional short-term stays at TU Delft and CNRS for testing enhanced fluorescence sensing application

    The working language is English. The PhD position is offered for a period up to three years.

    The position is to start as soon as possible and on April 1, 2023 at the latest.
