Modulated Ringdown Comb Interferometry for next-generation high complexity trace gas sensing
Qizhong Liang, Apoorva Bisht, Andrew Scheck +2
Gas samples relevant to health and environment typically contain a plethora of molecular species that span a huge concentration dynamic range. High-concentration molecules impose a…
Collision-induced C_60 rovibrational relaxation probed by state-resolved nonlinear spectroscopy
Lee R. Liu, P. Bryan Changala, Marissa L. Weichman +6
Quantum state-resolved spectroscopy was recently achieved for C60 molecules when cooled by buffer gas collisions and probed with a midinfrared frequency comb. This rovibrational qu…
Breath analysis by ultra-sensitive broadband laser spectroscopy detects SARS-CoV-2 infection
Qizhong Liang, Ya-Chu Chan, Jutta Toscano +6
Rapid testing is essential to fighting pandemics such as COVID-19, the disease caused by the SARS-CoV-2 virus. Exhaled human breath contains multiple volatile molecules providing p…
Ultra-sensitive multi-species spectroscopic breath analysis for real-time health monitoring and diagnostics
Qizhong Liang, Ya-Chu Chan, P. Bryan Changala +3
Breath analysis enables rapid, non-invasive diagnostics, as well as long-term monitoring, of human health through the identification and quantification of exhaled biomarkers. Here,…
