Real-time sensing with multiplexed optomechanical resonators

Autor: Lamberti, Fabrice, Palanchoke, Ujwol, Geurts, Thijs, Gely, Marc, Regord, Sebastien, Banniard, Louise, Sansa, Marc, Favero, Ivan, Jourdan, Guillaume, Hentz, Sebastien

Nanoelectromechanical resonators have been successfully used for a variety of sensing applications. Their extreme resolution comes from their small size at the cost of low capture area, making the "needle in a haystack" issue acute. This leads to poo

Optomechanical mass spectrometry

Autor: Sansa, Marc, Defoort, Martial, Brenac, Ariel, Hermouet, Maxime, Banniard, Louise, Fafin, Alexandre, Gely, Marc, Masselon, Christophe, Favero, Ivan, Jourdan, Guillaume, Hentz, Sébastien

It has been demonstrated in the recent years that nanomechanical mass spectrometry was well suited for the analysis of specific high mass species such as viruses. Still, the exclusive use of one-dimensional devices such as vibrating beams forces a tr

Optomechanical Resonating Probe for Very High Speed Sensing of Atomic Forces

Autor: Allain, Pierre Etienne, Schwab, Lucien, Misner, Colin, Gely, Marc, Mairiaux, Estelle, Hermouet, Maxime, Walter, Benjamin, Leo, Giuseppe, Hentz, Sébastien, Faucher, Marc, Jourdan, Guillaume, Legrand, Bernard, Favero, Ivan

Atomic force spectroscopy and microscopy (AFM) are invaluable tools to characterize nanostructures and biological systems. Most experiments, including state-of-the-art images of molecular bonds, are achieved by driving probes at their mechanical reso

Charge-independent mass spectrometry of single virus capsids above 100MDa with nanomechanical resonators

Autor: Dominguez-Medina, Sergio, Fostner, Shawn, Defoort, Martial, Sansa, Marc, Stark, Ann-Kathrin, Halim, Mohammad Abdul, Vernhes, Emeline, Gely, Marc, Jourdan, Guillaume, Alava, Thomas, Boulanger, Pascale, Masselon, Christophe, Hentz, Sébastien

Most technologies, including conventional mass spectrometry, struggle to measure the mass of particles in the MDa to GDa range. Although this mass range appears optimal for nanomechanical resonators, early nanomechanical-MS systems suffered from proh

Report

Single-particle Mass Spectrometry with arrays of frequency-addressed nanomechanical resonators

Autor: Sage, Eric, Sansa, Marc, Fostner, Shawn, Defoort, Martial, Gély, Marc, Naik, Akshay K., Morel, Robert, Duraffourg, Laurent, Roukes, Michael L., Alava, Thomas, Jourdan, Guillaume, Colinet, Eric, Masselon, Christophe, Brenac, Ariel, Hentz, Sébastien

One of the main challenges to overcome to perform nanomechanical Mass Spectrometry (NEMS-MS) analysis in a practical time frame stems from the size mismatch between the analyte beam and the extremely small nanomechanical detector area. We report here

Frequency fluctuations in silicon nanoresonators

Autor: Sansa, Marc, Sage, Eric, Bullard, Elizabeth C., Gély, Marc, Alava, Thomas, Colinet, Eric, Naik, Akshay K., Villanueva, Luis Guillermo, Duraffourg, Laurent, Roukes, Michael L., Jourdan, Guillaume, Hentz, Sébastien

Frequency stability is key to performance of nanoresonators. This stability is thought to reach a limit with the resonator's ability to resolve thermally-induced vibrations. Although measurements and predictions of resonator stability usually disrega
