Cell nuclei have lower refractive index and mass density than cytoplasm

Journal of Biophotonics, 2016
Common perception regards the nucleus as a densely packed object with higher refractive index (RI) and mass density than the surrounding cytoplasm. Here, the volume of isolated nuclei is systematically varied by electrostatic and osmotic conditions as ...

Engineering Hybrid Extracellular Vesicles for Functional mRNA Delivery

Advanced Functional Materials, EarlyView.
This study optimizes two methods for the generation of extracellular vesicle (EV)‐mimetic‐Lipid Nanoparticle (LNP) (CELLNPs) and EV‐LNP (HEVs) hybrid nanoparticles for messenger (mRNA) delivery. The authors screen lipid compositions to maximize hybrid nanoparticle formation and analyze the resulting nanoparticles with single particle characterization ...

Wavelength dependence of the refractive index of human colorectal tissues: comparison between healthy mucosa and cancer

Journal of Biomedical Photonics & Engineering, 2016
Biological tissues have individual optical properties that may be used as an identity card. The refractive index in particular, which can be measured directly, is very significant for the improvement or development of optical technologies in clinical ...

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, EarlyView.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Dynamically Adaptive Wrinkle‐Structured Light‐Regulating Films for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
A scalable, moisture‐responsive cellulose nanofibril/polyvinyl alcohol (CNF/PVA)‐glycerol film with switchable wrinkled surfaces for dynamic light regulation is developed. Compared to glass, it achieves tunable light diffusion for daylight harvesting, thermal regulation, and privacy control.

Ultrasensitive Magnetic Field Sensing Based on Refractive-Index-Matched Coupling

Sensors, 2017
An ultrasensitive magnetic field sensor is proposed and investigated experimentally. The no-core fiber is fusion-spliced between two pieces of single-mode fibers and then immersed in magnetic fluid with an appropriate value of refractive index. Under the

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...
