Renato Zenobi (born 1961 in Zurich) is a Swiss chemist. He is Professor of Chemistry at ETH Zurich. Throughout his career, Zenobi has made significant contribution to the development of analytical chemistry.
Zenobi received his MS degree from the ETH Zurich (Switzerland) in 1986 and PhD from the Stanford University (United States) in 1990. He was postdoctoral fellow at the University of Pittsburgh (United States; 1990–1991) and at the University of Michigan (United States; 1991). In 1992 he worked as Werner Fellow at the École Polytechnique Fédérale de Lausanne (Switzerland). He became assistant professor at the ETH Zurich in 1995, was promoted to associate professor in 1997, and to full professor in 2000. He is one of the associate editors of the Analytical Chemistry journal (ACS).
Zenobi's research areas include: laser-based analytical chemistry, electrospray and laser-assisted mass spectrometry, laser-surface interactions, near-field optical microscopy / spectroscopy as well as Single-Cell Analysis.
He has made contributions to the understanding of the ion formation mechanism in matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) and to the development of analytical tools for the nanoscale, most notably by inventing tip-enhanced Raman spectroscopy (TERS).
