Summary:

Poul Martin Bendix (Associate Professor, BendixLab/NBI) investigates physical properties of living cells using advanced optical techniques. Research: (1) optical tweezers for mechanosensing — GPCR mechanosensing with picoNewton force resolution, membrane curvature sensing by proteins (annexins, BAR-domain proteins); (2) thermoplasmonics — gold nanoparticle laser heating for controlled membrane microsurgery, cell fusion, and plasma membrane repair; (3) single-molecule biophysics — DNA-protein interactions using 4-trap optical tweezers (LUMICKS C-Trap) with STED imaging; (4) filopodia dynamics — twist and rotation of actin filaments; (5) Brillouin microscopy for cell mechanics; (6) COBM center management. GPCRmec consortium (Novo Nordisk). 2026 BPS Annual Meeting featured.

Summary:

Yakovlev develops label-free biomedical imaging: Brillouin micro-spectroscopy of cell/tissue viscoelasticity, impulsive stimulated Brillouin scattering, SERS and coherent-Raman diagnostics, and quantum-enhanced (photon-number-resolving, sub-shot-noise) optical imaging in collaboration with Agarwal/Scully. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides the biomedical, quantum-enhanced-imaging bridge for spin-sensor bio-applications.
