Department(s)/lab(s): Physics (LPENS) | Membrane Molecular Mechanisms Team (Pincet Lab) @ ENS Paris
Summary:

Pincet uses optical-tweezer single-molecule force spectroscopy and single-molecule imaging to quantify the energetics and kinetics of protein-membrane interactions underlying vesicle docking and fusion (synaptotagmin/SNARE machinery), and β€” as a 2020 ERC Synergy laureate β€” is testing whether the secretory pathway is organized as self-assembling 2D liquid-crystalline protein domains. The lab combines force-clamp optical tweezers with real-time single-molecule imaging for unprecedented spatiotemporal resolution of individual protein-membrane binding events.

Department(s)/lab(s): School of Physics | Melbourne Materials Institute Diamond Group (Prawer) @ UMelb
Summary:

Prawer is the founding figure of Melbourne diamond science, spanning colour-centre quantum technology, diamond surface chemistry and β€” unusually β€” clinical translation. His group developed the nitrogen-doped ultrananocrystalline diamond electrode arrays used in the Australian diamond bionic eye, a hermetically sealed, chronically implantable retinal stimulator that has been through human implantation; that is a rare example of an exotic-materials sensing/stimulation technology carried into human trials. In parallel the group works on diamond surface termination and functionalisation for near-surface NV sensing, nanodiamond bioconjugation, and diamond as a radiation-hard detector material. Positioned against the established body of NV-ensemble quantum sensing work β€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity β€” his surface- and materials-engineering work is precisely what sets the standoff distance, and hence the achievable pT/sqrt(Hz) sensitivity, of near-surface NV ensembles used for DEER and nanoscale NMR. Preferred attribute present: demonstrated human trials with a complex implanted technology.

Department(s)/lab(s): Molecular and Cellular Biology, Applied Physics | Prigozhin Lab @ Harvard
Summary:

Prigozhin develops multicolor electron microscopy using cathodoluminescent nanoprobe protein tags and time-resolved cryo-vitrification methods to capture the nanoscale, sub-second dynamics of GPCR signaling and biomolecular condensate formation, aiming to add molecular-scale color and temporal resolution to electron microscopy's inherent nanoscale spatial resolution.

Department(s)/lab(s): School of Physics | Reece Optical Trapping and Nanophotonics Laboratory @ UNSW
Summary:

Reece runs UNSW's optical trapping and nanophotonics laboratory. The group combines optical tweezers with spectroscopy and microfluidics to characterise individual nanoparticles and cells: trapping and spectroscopically interrogating plasmonic core-satellite assemblies (with Gooding and Tilley), measuring single-cell mechanics, and building porous-silicon and photonic-crystal resonant structures for label-free biosensing where the analyte shifts a cavity resonance. Positioned against the established body of NV-ensemble quantum sensing work β€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity β€” optical trapping is the standard way to hold a nanoscale sensor β€” including a nanodiamond hosting an NV ensemble at pT/sqrt(Hz) β€” at a controlled position inside a cell or fluid, and levitated-nanodiamond spin-mechanics is an active field that this group's capabilities map onto almost exactly. Strong practical fit for a bio-oriented quantum sensing candidate.

Department(s)/lab(s): LKB / Physics, Sorbonne UniversitΓ© | Atom Chips Group (Reichel/LKB) @ ENS Paris
Summary:

Jakob Reichel (Professor, LKB Atom Chips) leads work on fiber Fabry-Perot microcavities for atom-light quantum interfaces and miniaturised sensors. Research: (1) fiber Fabry-Perot microcavities β€” sub-micron mirrors on fibre tips enabling strong single-atom coupling; integrated directly into atom chips; (2) TACC (Trapped Atom Clock on a Chip) β€” Rb atom clock with 5.8Γ—10⁻¹³/βˆšΟ„ stability; ERC Advanced grant EQUEMI; (3) Sr optical-lattice cavity QED with quantum metrology; (4) MIREGA spinout β€” miniature portable greenhouse gas analyser combining FFP microcavities with telecom fibre optics for drone mounting; ERC Proof-of-Concept grant; (5) Rubidium CQED 'Sarocema' β€” individually addressable atom-tweezer array in fibre cavity for quantum simulation with long-range cavity-mediated interactions.

Department(s)/lab(s): School of Physics | Quantum Nanoscience Laboratory @ USyd
Summary:

Reilly's Quantum Nanoscience Laboratory works on the interface between quantum devices and the classical control hardware needed to run them at scale β€” custom VLSI CMOS operating below 100 mK, high-bandwidth dispersive readout, and cryogenic microwave engineering β€” a programme built up during his long association with Microsoft's quantum effort. A distinct and directly relevant second thread is the manipulation of spin states in nanoparticles for new imaging modalities in medicine: hyperpolarisation and spin-state engineering of nanoparticle contrast agents, which is quantum control applied to MRI. Positioned against the established body of NV-ensemble quantum sensing work β€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity β€” the cryo-CMOS readout chain he builds is exactly the enabling technology that would let a pT/sqrt(Hz) spin-ensemble sensor be multiplexed into an array rather than run one channel at a time; and the nanoparticle-MRI thread is an independent route into biological spin sensing. Large group, strong engineering culture, significant industry entanglement.

Department(s)/lab(s): Imaging Physics | Renaud Group @ TU Delft
Summary:

Renaud develops nonlinear and single-sided ultrasound methods to characterize bone and vascular tissue in vivo β€” quantifying cortical bone porosity, blood-flow, and microbubble/microcrack acoustic signatures β€” and collaborates closely with David Maresca's functional-ultrasound group on transcranial aberration-corrected Doppler imaging of the brain. This acoustic biosensing work extends the lab's push toward higher-sensitivity, non-invasive acoustic biomarkers analogous in spirit to other quantum-adjacent biosensing modalities.

Department(s)/lab(s): Imaging Physics (ImPhys) | Rieger Lab @ TU Delft
Summary:

Bernd Rieger works on computational super-resolution microscopy and live tissue imaging at the nanoscale. Research directions: (1) single-molecule localization microscopy (SMLM) algorithms and particle fusion; (2) 3D multi-label super-resolution imaging in tissue; (3) deep learning for biological image analysis. ERC grants; NL-BI Dutch Bioimaging consortium.

Department(s)/lab(s): Engineering | Institut Fresnel - MOSAIC Biophotonics Team @ CNRS
Summary:

Rigneault leads the MOSAIC team at Institut Fresnel, developing label-free nonlinear optical microscopy (CARS/SRS) for chemically-specific imaging of lipids and biomolecules in tissue, and pioneering lensless, hair-thin fiber-bundle endoscopes based on wavefront control for minimally invasive deep-tissue and in vivo biological imaging. He holds 17 patents in optical engineering and molecular spectroscopy for the life sciences.

Department(s)/lab(s): Biochemistry and Molecular Biology | Rock Lab @ UChicago
Summary:

Rock builds custom single-molecule fluorescence microscopes and optical tweezers to directly watch individual myosin motors move along the actin cytoskeleton in vitro and in living cells, quantifying motor stoichiometry, force generation, and navigation rules that organize cell shape and motility. Where NV-ensemble quantum sensors read out spin ensembles magnetically at pT/sqrt(Hz) sensitivity via DEER/NMR/T1 protocols, Rock's approach achieves single-fluorophore and single-motor mechanical/positional resolution using all-optical single-molecule methods.
