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.

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 — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — optical trapping is the standard way to hold a nanoscale sensor — including a nanodiamond hosting an NV ensemble at pT/sqrt(Hz) — 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.
