Detecting oxidation and reduction of Cytochrome c on Single Nanoparticles in Flow Using SERRS

Choi Y., Edel J.B., Albrecht T., Imperial College London, UK

Surface enhanced Raman spectroscopy (SERS) is a powerful tool used for observing molecules and their structural properties, due to their ability to enhance the otherwise weak Raman scattering signals on a roughened metal surface or [...]

Electrochemistry in nanopore/electrode structures – from pore fabrication to DNA sequencing-by-tunneling

Albrecht T., Imperial College London, UK

I will present results from my research group on nanopore-based single-biomolecule sensor with particular focus on electrode/nanopore structures. To this end, electrochemical concepts can be used for fabrication purposes, as well as for increased temporal [...]

Solid-state nanopores: a new tool for biomedical diagnostics

Khongkow M., Instuli E., Ivanov A., Albrecht T., Edel J.B., Imperial College London, UK

In this work, we present first results from the experimental implementation of an electrode/nanopore architecture with the aim of characterizing ion and DNA transport under the influence of a local alternating electric field. This includes [...]

Nanopore/electrode structures for single molecule biosensing

Albrecht T., Imperial College London, UK

In this contibution I will present some of our work on solid-state nanopores, the fabrication of nanopore/electrode structures and how these can be used for single-molecule biosensing applications (DNA, proteins etc.). Specifically, I will introduce [...]

Fuel cell catalysts based on core-shell nanoparticles

Xu H., Zalitis C., Rivera-Hernandez M., Albrecht T., Kucernak A., Imperial College London, UK

In this contribution, we focus on the different approaches to dispersing Pt and Co/Pt core/shell nanoparticles in solution and then depositing them on representative catalyst supports. These include gold or highly ordered pyrolytic graphite (HOPG) [...]
