A Biomimetic Norepinephrine‐Loaded Aligned Mineralized Collagen Scaffold for Coordinated Neurovascular, Osteogenic, and Immunomodulatory Repair of Critical‐Sized Bone Defects

Advanced Science, EarlyView.
Inspired by the composition and structure of native bone tissue and its complex interplay of biological signals, a norepinephrine‐loaded biomimetic mineralized electrocompacted collagen scaffold (NE‐MEC) is developed capable of simultaneously supporting osteogenesis, neural repair, angiogenesis, and immune modulation.

Small and Simple Molecular Structure Based Thermally Stable Ruthenium Precursor in Advancing Ruthenium ALD Process for Scaled Interconnect Metallization

Advanced Science, EarlyView.
A thermally robust (≈400 °C), critically small‐size‐simple ligand structure ruthenium (Ru) precursor enables exceptional growth per cycle (≈1.28 Å cycle−1), short incubation (≈8 cycles), ultralow resistivity (8.65 µΩ cm) and outstanding substrate selectivity via atomic layer deposition (ALD) process at high temperatures, overcoming prior Ru‐ALD ...

Phasor approach for Fluorescence Anisotropy

Single Molecule Spectroscopy and Superresolution Imaging XIV, 2021
Fluorescence anisotropy is a powerful tool for observing molecular rotational speed, which is widely applied for molecular conjugation measurements (quantitative assay, membrane tagging, and protein-protein interaction). Fluorescence anisotropy (r) can be obtained by subtracting horizontal polarized fluorescence (H) from vertical polarized fluorescence

Fluorescence Polarization Anisotropy in Microdroplets

The Journal of Physical Chemistry Letters, 2018
Chemical reactions can be greatly accelerated in microdroplets, but the factors that lead to acceleration are still being elucidated. Using rhodamine 6G (R6G) as a model compound, we studied the density distribution and fluorescence polarization anisotropy of this dye in water-in-oil microdroplets.

Fluorescence Anisotropy of Molecular Rotors

ChemPhysChem, 2011
AbstractWe present polarization‐resolved fluorescence measurements of fluorescent molecular rotors 9‐(2‐carboxy‐2‐cyanovinyl)julolidine (CCVJ), 9‐(2,2‐dicyanovinyl)julolidine (DCVJ), and a meso‐substituted boron dipyrromethene (BODIPY‐C12). The photophysical properties of these molecules are highly dependent on the viscosity of the surrounding solvent.

Fluorescence Anisotropy Controlled by Light Quenching

Photochemistry and Photobiology, 1998
We demonstrated that fluorescence anisotropy can be effectively decreased or increased in the presence of light quenching, depending on relative polarizations of excitation and quenching pulses. For parallel light quenching, anisotropy decreases to 0.103 and z-axis symmetry is preserved.

Time-Resolved Fluorescence Anisotropy Imaging

2013
Fluorescence can be characterized by its intensity, position, wavelength, lifetime, and polarization. The more of these features are acquired in a single measurement, the more can be learned about the sample, i.e., the microenvironment of the fluorescence probe.

Two-photon fluorescence anisotropy imaging

SPIE Proceedings, 2006
We have developed a novel method for imaging the fluorescence intensity and anisotropy by two-photon fluorescence microscopy and tested its capability in biological application. This method is applied to model sample including FITC and FITC-CD44 antibody solution and also FITC-CD44 stained cells.

Time-resolved fluorescence anisotropy measurements on fluorescently tagged amphiphilic micelles

Journal of Fluorescence, 1994
Block copolymers of polystyrene-block-poly)methacrylic acid) form multimolecular micelles in mixtures of 1,4-dioxane with a surplus of methanol at ambient temperatures. Micelles consist of compact polystyrene cores surrounded by outer shells formed by poly(methacrylic acid) and are in a reversible equilibrium with nonmicellized copolymer chains ...

Fluorescence emission and anisotropy from rhodamine dimers

Biophysical Chemistry, 1996
The absorption, fluorescence emission, and excitation fluorescence anisotropy spectra of a rhodamine dye in a water-glycerol solution at high concentration were investigated to determine spectroscopic properties of the ground state dimer. The combination of data from these spectra measured at several dye concentrations contained sufficient constraints ...
