Surface plasmons at single nanoholes in Au-films

open access: yes, 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).

Review of near-field optics and superlenses for sub-diffraction-limited nano-imaging

open access: yesAIP Advances, 2016
Near-field optics and superlenses for imaging beyond Abbe’s diffraction limit are reviewed. A comprehensive and contemporary background is given on scanning near-field microscopy and superlensing.

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

open access: yesFEBS 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.

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

open access: yes, 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 ...

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

open access: yesFEBS 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 ...

A near-field scanned microwave probe for spatially localized electrical metrology

open access: yes, 2005
We have developed a near-field scanned microwave probe with a sampling volume of approximately 10 micron in diameter, which is the smallest one achieved in near-field microwave microscopy.

Digital Twins for 3D Confocal Microscopy: Near-Field, Far-Field, and Comparison with Experiments

open access: yesSensors
To push the boundaries of confocal microscopy beyond its current limitations by predicting sensor responses for complex surface geometries, we build digital twins using three rigorous models, the finite element method (FEM), Fourier modal method (FMM ...

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

open access: yesNature 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.

KLK7 overexpression promotes an aggressive phenotype and facilitates peritoneal dissemination in colorectal cancer cells

open access: yesFEBS Open Bio, EarlyView.
KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...

Identification of Near-Field and Far-Field Using Confocal Microscopy Setup for Optical Sensing Applications

open access: yesASM Science Journal, 2019
The presence of near-field indicates the existence of evanescent waves, which is one of the important requirements for the development of an optical sensor.
