Two-photon microscopy: Visualization of kidney dynamics [PDF]

Kidney International, 2007
The introduction of two-photon microscopy, along with the development of new fluorescent probes and innovative computer software, has advanced the study of intracellular and intercellular processes in the tissues of living organisms. Researchers can now determine the distribution, behavior, and interactions of labeled chemical probes and proteins in ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Widefield-excitation two-photon single-pixel microscopy without temporal-focusing

JPhys Photonics
Two-photon microscopy (2PM) constitutes a key-enabling technology for imaging in weakly scattering specimens, delivering high-contrast signals through the quadratic dependence of fluorescence on excitation intensity.

Deep in vivo two-photon microscopy with a low cost custom built mode-locked 1060 nm fiber laser.

Biomedical Optics Express, 2016
Here we demonstrate that a mode-locked ytterbium fiber laser for two-photon fluorescence microscopy can be built for $13,000. The laser emits at a wavelength of 1060 nm with a usable average power of 1 W at a repetition rate of 40 MHz and a compressed ...

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

Advanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

Two-photon microscopy using fiber-based nanosecond excitation.

Biomedical Optics Express, 2016
Two-photon excitation fluorescence (TPEF) microscopy is a powerful technique for sensitive tissue imaging at depths of up to 1000 micrometers. However, due to the shallow penetration, for in vivo imaging of internal organs in patients beam delivery by an

Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

Advanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...
