Journey from natural to fabricated gas sensing photonic nanostructures: unexpected discoveries and societal impact

Existing spectroscopic and material-based gas sensors often degrade their performance in complex backgrounds. Thus, new sensing approaches are required with improved sensor selectivity and accuracy.  In this talk we analyze capabilities of natural and fabricated photonic three-dimensional nanostructures as sensors for detection of different gases. Our performance advances in detection of multiple gases with specific nanostructure designs were achieved by coupling spectral responses of these nanostructures with machine learning (a.k.a. multivariate analysis, chemometrics) tools.  Our new acquired knowledge from studies of natural and fabricated nanostructures allowed us to advance our design rules of sensing nanostructures toward needed gas selectivity for numerous gas monitoring scenarios at room and high temperatures for industrial, environmental, and other applications.
