Menzel's group develops computational scattered-light imaging methods, principally 3D Polarized Light Imaging (3D-PLI) and coherent Fourier scatterometry, to reconstruct the crossing-fiber architecture of unstained brain tissue at micrometer resolution without labeling. The lab combines birefringence/diattenuation measurements with finite-difference time-domain light-scattering simulations to push orientation resolution of nerve-fiber tracts beyond what diffusion MRI or standard histology can achieve, and is actively recruiting postdocs to extend the technique to new tissue types and label-free contrast mechanisms.
Metivier (PPSM) studies photochromic and fluorescent molecules at the single-molecule level - photoswitching kinetics, energy transfer and orientation-resolved imaging - underpinning super-resolution (RESOLFT/STORM-type) probes and molecular sensors. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is paralleled by molecular photoswitches enabling optical super-resolution.
Micolich works on semiconductor nanowire and organic/polymer nanoelectronic devices, with two strands relevant here: the physics of low-dimensional transport and noise in nanowire transistors, and the use of those devices as transducers at the interface with biological systems, where a nanowire field-effect transistor acts as an extremely local potentiometer sensitive to charge and potential changes at the cell membrane. The group has a strong record in noise spectroscopy — using 1/f and random telegraph noise as a diagnostic rather than a nuisance. 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 — nanowire FET bioelectronic sensing is the principal electrical competitor to NV-based bio-magnetometry: both aim to read out cellular electrophysiology without patch-clamping, one via magnetic fields at pT/sqrt(Hz), the other via local potential. Borderline inclusion, kept because the bio-interface sensing thread is genuine.
Miller designs synthetic VoltageFluor-class fluorescent dyes that report membrane potential with millisecond time resolution in neurons and other excitable cells, providing an optical alternative to patch-clamp electrophysiology for large-scale voltage imaging.
Mirkin invented spherical nucleic acids (SNAs) -- gold nanoparticles densely coated with a radial shell of oligonucleotides -- and their 'nanoflare' derivatives, which enter live cells without transfection agents and light up sequence-specifically upon binding intracellular mRNA, enabling live-cell gene-expression biosensing, circulating-tumor-cell isolation, and simultaneous mRNA detection/regulation. This label-based intracellular biosensing platform is offered as a borderline but well-established inclusion under the biosensing/dye-based imaging criterion.
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.
