The study of multiscale catalytic events is only possible by measuring what is going on inside the chemical reactor. This holds for both the chemical composition at high temporal and spatial resolution, as well as physical parameters such as mass flow and heat. An essential aspect of any measurement problem is that a sensor should not disturb its environment, while providing sufficient sensitivity and stability. Nanofabrication techniques such as electron beam, ion beam, or Talbot lithography are enabling technologies to address these sensing challenges by providing next generation sensor structures. 

In this project, the aim is to utilize these state-of-the-art lithographic techniques to fabricate nanometer-sized enhancement structures for mid-infrared and Raman spectroscopy. In addition, we will use nanolithography to fabricate metal nanowires to measure physical parameters such as flow or temperature.
