Near-field Nanoscopy of Terahertz Polaritons with Quantitative Dielectric Mapping
, 2021 Terahertz waves find broad use in physics, chemistry, and engineering for sensing applications. However, most experiments operate in the far-field, which precludes the observation of nanoscale features that affect the material response.

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Near-Field Angular Scan Enhancement of Antenna Arrays Using Metasurfaces
, 2020 In this publication we continue our previous work on extending the angular scan range of phased arrays using metasurfaces. We consider in detail scan enhancement using a single metasurface lens in the near-field of a source and provide analytical ...

Smaller is better: nanobodies meet NMR
FEBS Letters, EarlyView.Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

THE DEVELOPMENT OF A NEW KA-BAND NEAR-FIELD PLANAR MEASUREMENT SYSTEM FOR A DIGITAL PHASED ARRAY RADAR [PDF]
A near-field planar scanner is an electromechanical system whose objective is to obtain the far-field pattern of a mostly directive antenna by recording its electromagnetic fields in the near-field region by taking measurements at different points on an ...

In this paper, we present near-field optical images of nanostructures exhibiting an extraordinary transmission. These structures consist of annular aperture arrays engraved in a metallic film: they are quite promising structures for nanophotonics because

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Near-field edge fringes at sharp material boundaries
, 2017 We have studied the formation of near-field fringes when sharp edges of materials are imaged using scattering-type scanning near-field optical microscope (s-SNOM).
