Fourier Plane Tomographic Spectroscopy Reveals Orientation-Dependent Multipolar Plasmon Modes in Micrometer-Scale Janus Particles
Felix H. Patzschke, Frank Cichos
Plasmonic Janus particles, comprising dielectric cores with thin metallic caps, exhibit complex optical properties due to their asymmetric structure. Despite applications in active…
Unleashing Urease Protein Dynamics with Metamaterial Optical Tweezers
Domna G. Kotsifaki, Viet Giang Truong, Mirco Dindo +3
Investigating the dynamics of single biomolecules is essential for unlocking new frontiers in biophysics and medicine. Here, we present a transformative approach using metamaterial…
Roadmap on Deep Learning for Microscopy
Giovanni Volpe, Carolina Wählby, Lei Tian +72
Through digital imaging, microscopy has evolved from primarily being a means for visual observation of life at the micro- and nano-scale, to a quantitative tool with ever-increasin…
The physics of the photothermal detection of single absorbing nano-objects: A review
Markus Selmke, Frank Cichos
The literature on the theory of the photothermal imaging of single nano objects is reviewed. Several models have been devised to describe the signals magnitude, phase and shape in…
Energy Redistribution Signatures in Transmission Microscopy of Rayleigh- and Mie-particles
Markus Selmke, Frank Cichos
The transmission characteristics of a spherical (possibly multilayered) particle of arbitrary size under focused illumination are discussed within the generalized Lorenz-Mie theory…
Photonic Rutherford Scattering: A Classical and Quantum Mechanical Analogy in Ray- and Wave-Optics
Markus Selmke, Frank Cichos
Using Fermat's least optical path principle the family of ray-trajectories through a special but common type of a gradient refractive index lens, n(r)=n_0+Δn R/r, is solved analyti…
Photothermal Single Particle Microscopy
Markus Selmke, Marco Braun, Frank Cichos
Photothermal microscopy has recently complemented single molecule fluorescence microscopy by the detection of individual nano-objects in absorption. Photothermal techniques gain th…
