Nonredundant Raman imaging using optical eigenmodes

open access: yes, 2014
We thank funding from the UK Engineering and Physical Sciences Research Council namely grant EP/J01771X/1 and EU FP7 grant FAMOS.Various forms of imaging schemes have emerged over the last decade that are based on correlating variations in incident ...

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Electronically Preresonant Stimulated Raman Scattering Microscopy of Weakly Fluorescing Chromophores

open access: yes, 2023
Stimulated Raman Scattering microscopy is an important imaging technique. Its broader application, however, is hampered by its comparatively low sensitivity. Using organic fluorophores, it has recently been demonstrated that, similar to spontaneous Raman

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Evanescent stimulated Raman scattering in benzene-immersed fluorophosphate optical nanofibers [PDF]

open access: yesEPJ Web of Conferences
Optical nanofibers (ONFs) made from fluorophosphate glass (OHARA - FPM) enable strong confinement, low losses, and enhanced evanescent fields for nonlinear optics. We show that the HE₁₁ mode achieves high Raman gain (11.62 m−1·W−1) in a compact 10 cm ONF

Stimulated Raman Scattering

open access: yes, 1975
Stimulated Raman scattering was accidentally discovered by Woodbury and Ng in 1962 [7.1]. In studying Q-switching of a ruby laser by a nitrobenzene Kerr cell, they detected intense infrared radiation emitted from the Kerr cell, whose origin was not immediately identified.

Three-state model for femtosecond broadband stimulated Raman scattering

open access: yes, 2008
Stimulated Raman scattering (SRS) is analyzed with a three-state model. Using a diagrammatic density-matrix formalism, SRS by a pair of Raman pump and probe pulses, with observation along the probe direction, is described principally by eight terms.

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Stimulated Raman scattering in anatase TiO2 [PDF]

open access: yes, 2019
We report an experimental study of stimulated Raman scattering in anatase TiO2 at 4K under both resonance and off-resonance conditions. Efficient first - and higher-order stimulated Raman emission of the lowest optical mode was observed, especially for ...

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

open access: yesAdvanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.
