Short description

The main objective of this project is to study the optical response to electrochemical reactions in picoliter volumes inside a microcavity inline Mach-Zehnder interferomenter (µIMZI) fabricated in an optical fiber. We will focus on determination of neurotransmitter concentrations that are difficult to be measured by optical or electrochemical means individually. The work will be performed by a consortium of the group at Institute of Microelectronics and Optoelectronics, Warsaw University of Technology led by Prof. Mateusz Śmietana, the Charge Transfer in Hydrodynamic Systems group at the Institute of Physical Chemistry PAS led by Prof. Martin Jönsson-Niedziółka, and Prof. Marcin Koba from National Institute of Telecommunications.

Within the project realization we will develop: a highly sensitive optical-fiber-based structure known as a µIMZI; suitable electrodes and other electrochemical elements capable to be integrated with optical microsystem; a microfluidic system allowing for analyte injection and microcavity cleaning.
