RESEARCH, INNOVATION, COLLABORATION
Having the ability, expertise and technology to handle complex assays is critical to making big steps in the nano-world.
This project aims to develop a novel SERS electrode and an approach for highly sensitive and selective chemical analysis methodology of multi-component samples by a synergistic combination of electrochemical methods and Surface-enhanced Raman spectroscopy (SERS).
The proposed project is set to explore two novel and complementary approaches in bottom-up patterning of two-dimensional (2D) materials, and to understand the mechanisms behind the proposed methods.
During the two years of the project implementation, the project team obtained evidence for our original hypothesis regarding the polarization effects on the selection rules in the presence of nanoantennas for several configurations. For the first time, we discovered the "tip narrowing effect" that originates from the electromagnetic field enhancement in the presence of a strong image dipole in the configuration modeling the geometry of two strongly coupled nanoantennas.
In this environmentally conscious age, when the global community aims to reduce emissions and increase the reuse of raw materials, we found a way to impact these issues by developing a large-scale and environmentally friendly way to fabricate flexible electronics.
The work is dedicated to the development of effective materials for photocatalysis using 4-nitrobenzenethiol as a model molecule. Using plasmon-enhanced Raman spectroscopy (SERS and TERS), it was shown that external and internal system heating using plasmonic nanoparticles promotes a more active photocatalytic transition of the studied molecules.
