Summary

Prof. Christoph Langhammer presents his group’s work on integrating nanofluidics with single-particle plasmonics. He begins by motivating the need to study nanoparticles individually, citing ensemble heterogeneity and the ability to see beyond error bars. He then introduces their approach of embedding plasmonic nanoparticles in nanofluidic channels to control mass transport. The talk covers two main applications: sensing and heterogeneous catalysis. For sensing, they demonstrate refractive index sensitivity, on-chip referencing, and detection of molecular binding. For catalysis, they present a setup combining nanofluidic chips with mass spectrometry to study reactions on single nanoparticles, exemplified by CO oxidation on copper nanoparticles. The talk concludes with insights into the potential of this integrated platform for lab-on-a-chip devices.
