Near-Field Nano-Focusing and Nano-Imaging of Dielectric Microparticle Lenses [PDF]

open access: yesNanomaterials
Compared with traditional far-field objective lenses, microparticle lenses have a distinct advantage of nonobservance of the diffraction limit, which has attracted extensive attention for its application in subwavelength photolithography and super ...

Flexible Ag Microparticle/MXene-Based Film for Energy Harvesting

open access: yesNano-Micro Letters, 2021
Flexible Ag microparticle/MXene-based energy-harvesting films were fabricated via simple spraying and hot-pressing. Optimal film shows high conductivity and effective electro/photo-thermal abilities. It can be easy assembled single-electrode TENG and the

Investigating PLGA microparticle swelling behavior reveals an interplay of expansive intermolecular forces

open access: yesScientific Reports, 2021
This study analyzes the swelling behavior of native, unmodified, spherically uniform, monodisperse poly(lactic-co-glycolic acid) (PLGA) microparticles in a robust high-throughput manner.

Diversity of extracellular vesicles in human ejaculates revealed by cryo-electron microscopy [PDF]

open access: yesJournal of Extracellular Vesicles, 2015
Human ejaculates contain extracellular vesicles (EVs), that to a large extent are considered to originate from the prostate gland, and are often denominated “prostasomes.” These EVs are important for human fertility, for example by promoting sperm ...

Physical evaluation of lipstick contains encapsulated beet (Beta vulgaris linn.) root water extract in maltodextrin [PDF]

open access: yesPharmaciana, 2020
The natural dyes from beet (Beta vulgaris Linn) (BV) roots can be used as coloring agents in lipsticks. However, the dye has low stability in high temperature and light and can be oxidized by air.

Research progress of tumor‐derived extracellular vesicles in the treatment of malignant pleural effusion

open access: yesCancer Medicine, 2023
Vesicles, also known as “microparticles”, are vesicle‐like structures that are released outside the cell in a “sprouting” manner when the cytoskeleton is changed during cell activation or apoptosis, with a diameter of about 100–1000 nm, and are carriers ...

Dispersing hydrophobic natural colourant β-carotene in shellac particles for enhanced stability and tunable colour [PDF]

open access: yesRoyal Society Open Science, 2017
Colour is one of the most important visual attributes of food and is directly related to the perception of food quality. The interest in natural colourants, especially β-carotene that not only imparts colour but also has well-documented health benefits ...

Microspinning: Local Surface Mixing via Rotation of Magnetic Microparticles for Efficient Small-Volume Bioassays [PDF]

open access: yes, 2020
The need for high-throughput screening has led to the miniaturization of the reaction volume of the chamber in bioassays. As the reactor gets smaller, surface tension dominates the gravitational or inertial force, and mixing efficiency decreases in small-

Extracellular Vesicles in Autologous Cell Salvaged Blood in Orthopedic Surgery

open access: yesSurgeries, 2021
(1) Background: Cell salvage is highly recommended in orthopedic surgery to avoid allogeneic transfusions. Preparational steps during cell salvage may induce extracellular vesicle (EV) formation with potential thrombogenic activity.
