Recent advances in Raman probes for multiplexed bioimaging

Inflammation and Regeneration
Bond-selective vibrational imaging techniques, such as Raman spectroscopy, are opening up many applications that were previously considered impossible or inaccessible by other means, such as fluorescence imaging.

Raman spectral band imaging for the diagnostics and classification of canine and feline cutaneous tumors

Veterinary Quarterly
This study introduces Raman imaging technique for diagnosing skin cancer in veterinary oncology patients (dogs and cats). Initially, Raman spectral bands (with specificity to certain molecular structures and functional groups) were identified in formalin-

Subsurface Raman Imaging with Nanoscale Resolution [PDF]

Nano Letters, 2006
We report on chemically specific, subsurface imaging with high spatial resolution. Using tip-enhanced Raman spectroscopy, we probe carbon nanotubes buried beneath a host dielectric media. We demonstrate our ability to map and resolve specific vibrational modes with 30 nm spatial resolution for dielectric layers with different thicknesses.

Robust Electrocaloric Performance Enabled by Highly‐Polar Frustrated Nanodomains in NaNbO3‐Based Ferrodistortive Relaxor

Advanced Functional Materials, EarlyView.
P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.

Raman microspectroscopie en Raman imaging

Photonics magazine, 1994
Door haar grote molecuulspecifiteit kan Ramanspectroscopie gebruikt worden voor het herkennen/aantonen van moleculen in een preparaat. Het is ook mogelijk om de secundaire structuur van biologische macromoleculen zoals DNA en eiwitten te bestuderen en informatie te verkrijgen over interakties tussen moleculen. Dit alles zonder het gebruik van labels of

Raman Spectroscopy and Imaging for Cancer Diagnosis

Journal of Healthcare Engineering, 2018
Raman scattering has long been used to analyze chemical compositions in biological systems. Owing to its high chemical specificity and noninvasive detection capability, Raman scattering has been widely employed in cancer screening, diagnosis, and intraoperative surgical guidance in the past ten years. In order to overcome the weak signal of spontaneous

Raman Imaging and Electronic Properties of Graphene [PDF]

, 2008
Graphite is a well-studied material with known electronic and optical properties. Graphene, on the other hand, which is just one layer of carbon atoms arranged in a hexagonal lattice, has been studied theoretically for quite some time but has only recently become accessible for experiments.

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.
