Single-molecule peptide fingerprinting [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance Protein sequencing remains a challenge for small samples. A sensitive sequencing technology will create the opportunity for single-cell proteomics and real-time screening for on-site medical diagnostics. To resolve protein identity, we previously developed a computational algorithm that analyzes the ordered sequence of ...

Sphingomyelin metabolism underlies Ras excitability for efficient cell migration and chemotaxis
Cell Structure and Function, 2023 In eukaryotic motile cells, the active Ras (Ras-GTP)-enriched domain is generated in an asymmetric manner on the cell membrane through the excitable dynamics of an intracellular signaling network.

Thermopower of Single-Molecule Devices
, 2004 We investigate the thermopower of single molecules weakly coupled to metallic leads. We model the molecule in terms of the relevant electronic orbitals coupled to phonons corresponding to both internal vibrations and to oscillations of the molecule as a ...

Single-molecule strong coupling at room temperature in plasmonic nanocavities
Nature, 2016 Photon emitters placed in an optical cavity experience an environment that changes how they are coupled to the surrounding light field. In the weak-coupling regime, the extraction of light from the emitter is enhanced.
