Branton is a pioneer of nanopore sensing, having shown that single DNA/RNA molecules threading through a nanopore produce ionic-current signatures usable for single-molecule sequencing — foundational work underlying the modern solid-state and biological nanopore-sequencing industry, and a direct fit to the biosensing/single-molecule filter criterion.

Brasselet is a CNRS researcher at Institut Fresnel developing polarization- and orientation-resolved fluorescence microscopy, using controlled excitation and detection polarization states to map the 3D orientation and organization of fluorescent probes and biomolecular assemblies (e.g. lipid order, amyloid and cytoskeletal structures) at and beyond the single-molecule level, including recent work on the mathematical foundations of polarimetric microscopy.

Breeze is a senior research fellow at UCL working on room-temperature solid-state masers. Research directions: (1) Pentacene maser — first demonstration of a room-temperature, continuous-wave solid-state maser (Science 2018) using photoexcited triplet-state pentacene in p-terphenyl crystal; achieving amplification with noise temperature near 1 K; (2) Diamond NV maser — developing NV-center-based maser for ultra-low-noise microwave amplification at room temperature, relevant to quantum sensing readout chains; (3) Maser applications — quantum-limited amplification for dark matter searches, MRI signal amplification, and quantum communication repeaters; (4) Spin dynamics — understanding triplet-state dynamics in organic crystals for spin polarization control. Strong relevance to quantum-limited microwave sensing.

Daan Brinks develops all-optical electrophysiology tools for neuroscience. His lab engineers genetically-encoded voltage indicators (GEVIs) and combines them with optogenetics to read out and control neural circuit activity. Key directions: (1) engineering bright, fast GEVIs with improved photostability and voltage sensitivity; (2) multiplexed all-optical neural circuit mapping; (3) identifying rare aggressive cancer cells using voltage-sensitive dyes. His voltage imaging approach represents cutting-edge biosensing at the intersection of photonics and neuroscience.

Bustamante is a founding figure of single-molecule biophysics, using optical and magnetic tweezers to measure the forces and torques generated by molecular motors (RNA polymerase, viral packaging motors, the ribosome) as they act on individual nucleoprotein complexes. The lab continues to push single-molecule force spectroscopy toward sub-piconewton, millisecond resolution to resolve mechanochemical intermediates invisible to bulk assays.

Nobel laureate Steven Chu's group spans laser cooling/trapping of atoms and single-molecule biophysics, using optical and magnetic tweezers and single-molecule fluorescence to study DNA/RNA folding, molecular motors, and signal transduction -- one of the earliest applications of AMO-derived single-particle measurement precision to living systems.

Cohen's lab develops genetically encoded fluorescent voltage indicators and all-optical electrophysiology ('Optopatch') to simultaneously stimulate and image membrane voltage in individual neurons and cardiomyocytes at the single-cell and network level, combining protein engineering, optics, and theory to push the temporal and spatial resolution of bioelectrical imaging well past conventional patch-clamp limits.

Conolly builds Magnetic Particle Imaging (MPI) scanners, a tracer-based imaging modality that detects the nonlinear magnetization response of superparamagnetic nanoparticles with high sensitivity, safety, and zero background signal from tissue, alongside compressed-sensing MRI methods.

Cui develops vertical nanopillar electrode and optical sensor arrays that interface with the cell membrane to probe curvature-sensitive signaling, and pairs them with 3D super-resolution (single-molecule localization) microscopy to resolve nanoscale protein organization at the nano-bio interface with 10-20 nm precision, well past the optical diffraction limit.

Develops photonic-crystal-based optical biosensors and photonic-resonator-enhanced microscopy for digital-resolution, single-nanoparticle/single-quantum-dot biodetection, applied to protein, exosome, and nucleic acid diagnostics.
