Nobel laureate W. E. Moerner, who first detected and studied single molecules optically, now develops engineered point-spread-function and orientation-resolved single-molecule localization microscopy methods to track individual biomolecules and their rotational dynamics in cells with nanometer precision, well beyond the optical diffraction limit.
Monzel holds the biophysics/biophotonics professorship at Stuttgart's 2nd Institute of Physics. The group develops multiparametric imaging spectroscopy and high-resolution light microscopy -- combining super-resolution, fluorescence-fluctuation and lifetime-resolved methods -- to read out several observables at once in living cells and in biomimetic model membranes, and pairs this with magnetic nanoparticles used to apply and sense forces on cell-surface receptors (magnetogenetic control of signalling). Single-molecule analysis inside cells is an explicit focus. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is the closest thing at Stuttgart to a natural biological host for in-cell quantum sensing: the group already does single-molecule-resolution live-cell imaging and already works with magnetic nanoparticles, so nanodiamond relaxometry/thermometry would slot in with the readout stack it already runs. Relatively new appointment -- good moment to join.
Jörg Müller's Quantum Metrology group works on next-generation optical atomic clocks and superradiant lasers. Key experiments: cold strontium continuous superradiant laser (subnatural linewidth, pushing beyond traditional clock limitations); microresonator-based frequency combs; ultra-stable optical reference cavities; and cavity QED many-atom systems for clocks and sensing. The group is part of the EU iqClock project targeting operational optical lattice clocks.
Muller designs wireless, miniaturized CMOS integrated circuits for closed-loop neural recording and stimulation (including the WAND platform), pushing implantable bioelectronic sensing toward fully autonomous, battery-free operation.
Mulvaney directs the ARC Centre of Excellence in Exciton Science and runs Melbourne's nanoscience laboratory. The group's distinctive capability is single-particle and single-emitter optical spectroscopy: photon-antibunching and blinking statistics from individual quantum dots and perovskite nanocrystals, photothermal and dark-field spectroscopy of individual metal nanoparticles, and the electrochemical control of single-nanocrystal charge state. Applications run from LEDs and solar cells to quantum-dot probes for single-particle tracking in cells. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his single-emitter photon-statistics measurements share the shot-noise-limited photon-counting methodology of NV-ensemble ODMR readout, and the group's nanocrystal probes are direct competitors/complements to nanodiamond in cellular sensing. Large, well-resourced group.
Murray develops mid-infrared photonic sources and detectors and combines mid-IR spectroscopy with mass-spectrometry imaging to provide complementary optical and biochemical maps of tissue for biomedical sensing.
Natrajan's group develops luminescent lanthanide complexes for chemical and biological sensing. Research directions: (1) Time-gated lanthanide luminescence sensing — long-lifetime Eu3+, Tb3+, and Yb3+ complexes with millisecond emission lifetimes for background-free sensing in cells and tissue; (2) Intracellular sensing — luminescent probes for sensing O2, pH, viscosity, and specific enzymes inside living cells with spatiotemporal resolution; (3) Chiral discrimination — circularly polarized luminescence (CPL) from Eu3+ complexes for enantioselective sensing; (4) Responsive probes — switchable lanthanide complexes as ratiometric sensors for biomedical imaging. The long-lifetime emission enables time-gating strategies analogous to quantum sensing protocols.
Needleman combines polarized-light microscopy, second-harmonic generation, single-molecule tracking, and fluorescence-lifetime (FLIM) metabolic imaging to study self-organization of the mitotic spindle and, in a clinically translated direction, non-invasive metabolic imaging of human oocytes and embryos for IVF viability assessment — an orientation- and lifetime-resolved imaging program with an active human-trial/clinical translation component.

Nguyen's group at UCL (based at Royal Institution) focuses on magnetic and fluorescent nanoparticles for biomedical sensing and therapy. Research directions: (1) Magnetic nanoparticle synthesis — iron oxide (SPION) and other magnetic nanoparticles with controlled size, shape, and surface chemistry for MRI contrast and magnetic hyperthermia; (2) Biosensing platforms — functionalized nanoparticles as MRI-detectable sensors for specific biomolecular targets; magnetic particle imaging (MPI) for real-time tracking; (3) Plasmonic nanoparticles — gold nanoparticles for optical biosensing and photothermal therapy; (4) Fluorescent nanoparticles — QD- and dye-conjugated probes for live-cell imaging. Relevant to quantum sensing through magnetic nanoparticle platforms.
