Light interaction with nanosized material is remarkably different from its bulk counterpart, evidenced, for example, by the brightly colored suspensions of especially noble metal nanoparticles. During his studies, Hans researched the combination of optical and electrochemical read out at a single substrate, by immobilizing these so-called plasmonic noble metal nanoparticles on transparent conducting substrates. Being able to precisely manipulate the electric potential of immobilized noble metal nanoparticle potentiates high sensitivity and fidelity chemical and biological detection in combined optical and electrochemical assays, but also allows manipulation of the optical properties of the immobilized nanoparticles through external electrical stimuli.

The presented systems were realized through a combination of clean room fabrication, 3D printing, and in situ modification, and the obtained results are of broader use in e.g. biotechnological applications.

The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
