Near-Field Microwave Microscopy of Materials Properties

, 2000
Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad ...

Surface plasmons at single nanoholes in Au-films

, 2004
The generation of surface plasmon polaritons (SPP's) at isolated nanoholes in 100 nm thick Au films is studied using near-field scanning optical microscopy (NSOM).

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Scattering-type scanning near-field optical microscopy with low-repetition-rate pulsed light source through phase-domain sampling

Nature Communications, 2016
Low repetition rate lasers are suitable for studying nonlinear optical phenomena, while near-field microscopy allows high spatial resolution for nanomaterial characterisation. Here, Wang et al.

Determination of electric field, magnetic field, and electric current distributions of infrared optical antennas: A nano-optical vector network analyzer

, 2010
In addition to the electric field E(r), the associated magnetic field H(r) and current density J(r) characterize any electromagnetic device, providing insight into antenna coupling and mutual impedance.

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Optically induced forces in scanning probe microscopy

Nanophotonics, 2014
Typical measurements of light in the near-field utilize a photodetector such as a photomultiplier tube or a photodiode, which is placed remotely from the region under test.

Near-field coupling of gold plasmonic antennas for sub-100 nm magneto-thermal microscopy

, 2017
The development of spintronic technology with increasingly dense, high-speed, and complex devices will be accelerated by accessible microscopy techniques capable of probing magnetic phenomena on picosecond time scales and at deeply sub-micron length ...

Near-Field Scanning Optical Microscopy (NSOM)

SPIE Proceedings, 1986
Superresolution optical images have been generated with near-field scanning optical microscopy (NSOM). The underlying concept is presented and several modes of operation are discussed. A resolution based on edge sharpness of 70 nm or better has been demonstrated with two different instruments. Images have been obtained which characterize the resolution
