Light-sheet microscopy: a tutorial [PDF]

, 2018
This paper is intended to give a comprehensive review of light-sheet (LS) microscopy from an optics perspective. As such, emphasis is placed on the advantages that LS microscope configurations present, given the degree of freedom gained by uncoupling the

Description and performance of a highly sensitive confocal Raman microspectrometer [PDF]

, 1991
A confocal Raman microspectrometer was developed for the study of small biological objects such as single living cells and metaphase and polytene chromosomes.

Time-Encoded Raman: Fiber-based, hyperspectral, broadband stimulated Raman microscopy [PDF]

, 2014
Raman sensing and Raman microscopy are amongst the most specific optical technologies to identify the chemical compounds of unknown samples, and to enable label-free biomedical imaging with molecular contrast.

Widespread abiotic methane in chromitites [PDF]

, 2018
Recurring discoveries of abiotic methane in gas seeps and springs in ophiolites and peridotite massifs worldwide raised the question of where, in which rocks, methane was generated.

Frustration of crystallisation by a liquid–crystal phase [PDF]

, 2017
Frustration of crystallisation by locally favoured structures is critically important in linking the phenomena of supercooling, glass formation, and liquid-liquid transitions.

High-Resolution Near-Field Raman Microscopy of Single-Walled Carbon Nanotubes [PDF]

, 2003
We present near-field Raman spectroscopy and imaging of single isolated single-walled carbon nanotubes with a spatial resolution of ≈25  nm. The near-field origin of the image contrast is confirmed by the measured dependence of the Raman scattering ...

Correlative Raman–Electron–Light (CREL) Microscopy Analysis of Lipid Droplets in Melanoma Cancer Stem Cells

Biosensors, 2022
Among all neoplasms, melanoma is characterized by a very high percentage of cancer stem cells (CSCs). Several markers have been proposed for their identification, and lipid droplets (LDs) are among them.

A Carbon Nanofilament-Bead Necklace [PDF]

, 2008
Carbon nanofilaments with carbon beads grown on their surfaces were successfully synthesized reproducibly by a floating catalyst CVD method. The nanofilaments hosting the pearl-like structures typically show an average diameter of about 60 nm, which ...

Label-Free Live-Cell Imaging with Confocal Raman Microscopy [PDF]

Biophysical Journal, 2012
Confocal Raman spectroscopy is a noninvasive alternative to established cell imaging methods because it does not require chemical fixation, the use of fluorescent markers, or genetic engineering. In particular, single live-cell, high-resolution imaging by confocal Raman microscopy is desirable because it allows further experiments concerning the ...

Grading of Melanoma Tissues by Raman MicroSpectroscopy

Engineering Proceedings, 2023
Melanoma is one of the most aggressive forms of cancer. Early-stage diagnosis is therefore a landmark for the success of the therapies and to improve the prognosis.
