Ultraviolet direct absorption microscopy for single particle protein/nucleic acid quantification
C. J. Richards, D. van de Lockand, D. Wolters +1
Bio-nanoparticles are pivotal to next generation nanotherapeutics, but providing single-particle biomolecular characterization remains a crucial challenge. Herein we present ultra-…
Motion-Based Beamshape Recovery Enables Precision Nanoparticle Sizing
D-Dré K. J. M. J. Braam, Daan Wolters, Matz Liebel
Label-free all-optical nanosizing approaches based on interferometric or darkfield-imaging infer size, composition, or shape from single-particle scattering signals, but these sign…
Bidirectional phase sensitivity in holographic phototransient microscopy
Emmanuel Kotu Robertson, Dennis van de Lockand, Matz Liebel
Mid-infrared photothermal microscopy combines the chemical specificity of infrared absorption with the spatial resolution of visible-light detection, but practical implementations…
Sub-Nyquist time-domain surface-enhanced Raman mapping
Ting Wang, I. Brian Becerril-Castro, Ana Sousa-Castillo +3
Surface-enhanced Raman scattering (SERS) combines analyte-specificity and single-molecule sensitivity, but its potential is limited by slow readout where sophisticated nanosensors…
The next dimension: Digital holography for 3D interferometric scattering
Jaime Ortega Arroyo, Matz Liebel
We provide detailed experimental guidelines for implementing digital holography in the context of high-sensitivity interferometric scattering (iSCAT) based nanosizing applications.…
Time-resolved infrared photothermal imaging: From transient observations towards the steady-state
Dennis van de Lockand, Daan Wolters, Matz Liebel
Mid-infrared photothermal microscopy is a highly promising imaging technique that enables spatially resolved vibrational fingerprinting. The combination of infrared induced heating…
Ultra-broadband Optical Diffraction Tomography
Martin Hörmann, Franco V. A. Camargo, Niek F. van Hulst +2
Optical diffraction tomography (ODT) is a powerful non-invasive 3D imaging technique, but its combination with broadband light sources is difficult. In this study, we introduce ult…
Widefield phototransient imaging for visualizing 3D motion of resonant particles in scattering environments
Matz Liebel, Franco V. A. Camargo, Giulio Cerullo +1
Identifying, visualising and ultimately tracking dynamically moving non-fluorescent nanoparticles in the presence of non-specific scattering is a long-standing challenge across the…
One-shot phase image distinction of plasmonic and dielectric nanoparticles
Lisa Saemisch, Niek F. van Hulst, Matz Liebel
Nanoscale phase-control is one of the most powerful approaches to specifically tailor electrical fields in modern nanophotonics. Especially the precise sub-wavelength assembly of m…
Precise nanosizing with high dynamic range holography
Unai Ortiz-Orruño, Ala Jo, Hakho Lee +2
Optical sensing is one of the key-enablers of modern diagnostics. Especially label-free imaging modalities hold great promise as they eliminate labeling procedures prior to analysi…
Observation of giant and tuneable thermal diffusivity of Dirac fluid at room temperature
Alexander Block, Alessandro Principi, Niels C. H. Hesp +8
Conducting materials typically exhibit either diffusive or ballistic charge transport. However, when electron-electron interactions dominate, a hydrodynamic regime with viscous cha…
Statistical analysis of many single-molecule encounters reveals plasmonic resonance dependent nanoantenna-molecule interactions
Lisa Saemisch, Matz Liebel, Niek van Hulst
The nanoscale interaction between single emitters and plasmonic structures is traditionally studied by relying on near-perfect, deterministic, nanoscale-control. This approach is u…
