Study of dendritic spine compartmentalization : a correlative fluorescence light microscopy-electron microscopy approach [PDF]

, 2014
Neurons communicate with each other through synapses. Most excitatory synapses contact small protrusions called dendritic spines. Spines are connected to dendrites by a very thin stalk called the “spine neck” which restricts diffusion between the spine ...

Detection by fluorescence microscopy of N-aminopeptidases in bacteria using an ICT sensor with multiphoton excitation: Usefulness for super-resolution microscopy

, 2020
Bacterial proteases are relevant in pathological processes such as the survival, growth and development of microorganisms. In particular alanine amino peptidase (pepN), which is present in Gram (−) bacteria, is the only peptidase responsible for the ATP ...

Fluorescence microscopy imaging of mitochondrial metabolism in cancer cells

Frontiers in Oncology, 2023
Mitochondrial metabolism is an important contributor to cancer cell survival and proliferation that coexists with enhanced glycolytic activity. Measuring mitochondrial activity is useful to characterize cancer metabolism patterns, to identify metabolic ...

The analysis of fluorophore orientation by multiphoton fluorescence microscopy [PDF]

SPIE Proceedings, 2010
The accessibility of tunable, ultrafast laser sources has spurred the development and wide application of specialized microscopy techniques based on chromophore fluorescence following two- and three-photon absorption. The attendant advantages of such methods, which have led to a host of important applications including three-dimensional biological

Self-confocal NIR-II fluorescence microscopy for multifunctional in vivo imaging

Journal of Innovative Optical Health Sciences
Fluorescence imaging in the second near-infrared window (NIR-II, 900–1880[Formula: see text]nm) with less scattering background in biological tissues has been combined with the confocal microscopic system for achieving deep in vivo imaging with high ...

Multimodal multiphoton imaging for label-free monitoring of early gastric cancer

BMC Cancer, 2019
Background Early gastric cancer is associated with a much better prognosis than advanced disease, and strategies to improve prognosis is strictly dependent on earlier detection and accurate diagnosis.

Two-photon laser scanning fluorescence microscopy using photonic crystal fibre

, 2004
We report the application of a simple yet powerful modular pulse compression system, based on photonic crystal fibres which improves upon incumbent twophoton laser scanning fluorescence microscopy techniques.

Optical Biomedical Imaging Reveals Criteria for Violated Liver Regenerative Potential

Cells, 2023
To reduce the risk of post-hepatectomy liver failure in patients with hepatic pathologies, it is necessary to develop an approach to express the intraoperative assessment of the liver’s regenerative potential.

Multiphoton fluorescence lifetime imaging microscopy (FLIM) and super-resolution fluorescence imaging with a supramolecular biopolymer for the controlled tagging of polysaccharides.

Nanoscale, 2019
A new supramolecular polysaccharide complex, comprising a functionalised coumarin tag featuring a boronic acid and β-d-glucan (a natural product extract from barley, Hordeum Vulgare) was assembled based on the ability of the boronate motif to ...
