The inclusion of biological molecules into nanoscale electrical devices has many potential applications in biomedical engineering, biosensors, and molecular electronics. Nanofabrication techniques have progressed significantly, and a new combination of techniques could provide a fast and easy method of measuring the electrical properties of nanostructures, including individual molecules. DNA has several unique advantages for use in molecular electronics, but its electrical properties must be properly characterized before its potential can be realized in this dynamic field. Many current methods for determining the conductivity of DNA have provided inconsistent results, thereby hindering the ability of scientists and engineers to utilize DNA fully in molecular electronics. This project aims to utilize nanofabrication techniques to create a novel method for electrically characterizing individual nanostructures, including DNA.

Functional Nanostructures
Written by Lukas Schmidt-Mende
Functional Nanostructures for Hybrid Solar Cells One current project aims to fabricate hybrid solar cells combining metal-oxide nanostructures and organic materials. The control of film morphology, alignment of molecules and controlled assembly of materials at the nanometer scale is necessary for efficient devices. This research will address the control of the structure of the active layer by introducing a nano-structured metal-oxide electrode as a template for the organic materials. The interfacial interactions between the materials have to be investigated and manipulated to achieve spontaneous self-assembly into the desired morphology and device structure.
