Light Emitting Electrochemical Cells

Organic LEDs are of interest for display and lighting applications for their potential as high efficiency emitters with low production costs. My research involves creating organic LEDs from small molecules possessing ionic conductivity. These materials exhibit efficient operation in single layer devices, maintaining ease of fabrication with high performance. Our initial research has brought about advances in the luminance and response time of these devices to meet US Department of Energy benchmarks for lighting. These simple devices allow for direct investigation of the fundamental physics governing device operation. Ionic space charge effects also enable fabrication of devices with unique architectures, such as cascaded lighting panels and nanoscale emitters.

Electrochemical Biosensors

Point of care detectors are an emerging technology for near-patient disease diagnosis, and early detection of diseases such as cancer is of paramount importance for favorable prognosis. My goal is to implement eletrochemical devices for cancer and genetic diseases. This requires detection of sophisticated cellular biomarkers such as proteins and gene fragments in complex media. To accomplish this, my research exploits DNA as a powerful recognition element and transducer in biosensing devices. Furthermore, this technology enables a study of subtle, single-base damange in DNA, enabling new insight into disease states and drug activity.

DNA in Nanoscale Electronics

DNA can serve as a nanoscale scaffold for the construction of molecular wires and molecular semiconductor devices. We study the electronic and self-assembly properties of DNA given its inherent novelty and potential for self-organizing nanoscale integrated circuits.
