A Multifunctional Photothermal Electrospun PLGA/MoS2@Pd Nanofiber Membrane for Diabetic Wound Healing in ssalimpour

Finding a green approach for silver nanoparticle (AgNP) synthesis and as an adsorbent for safe contaminant removal in water has become a challenge. In this study, AgNP were green synthesised into a biopolymer matrix (natural rubber latex/polyvinyl alcohol (PVA/NRL)) via electrospinning. Efficiency of the synthesised nanofibre composites in removing mercury (Hg) from an aqueous solution was examined. SEM and TEM analysis showed that AgNP were more visible on the fibre’s surface at a lower concentration (0.01 M AgNP), whilst at a higher concentration (0.015 M AgNP), relatively more AgNP were found within the fibre. The average sizes of the AgNP were relatively larger (8.15 ± 0.09 nm) in 0. 2023-11-01

In order to manipulate the complex behavior of cells in a 3-dimensional (3D) environment, it is important to provide the microenvironment that can accurately portray the complexity of highly anisotropic tissue structures. However, it is technically challenging to generate a complex microenvironment using conventional biomaterials that are mostly isotropic with limited bioactivity. In this study, the gelatin-hyaluronic acid hydrogel incorporated with aqueous-dispersible, short nanofibers capable of in situ alignment is developed to emulate the native heterogeneous extracellular matrix consisting of fibrous and non-fibrous components. The gelatin nanofibers containing magnetic nanoparticles, 2024-05-01

Nanoscale optical fibers, capable of confining light at the nanoscale, exhibit nonlinear effects and generate a strong evanescent field interacting with the surrounding environment. In this study, we compared various nanofibers composed of different glasses, closely matching the refractive index of silica, while immersed in acetone. Our objective was to optimize the Kerr effect contributions from either the core or the cladding, dependent on factors such as nanofiber dimensions, core optical properties, and the effective area of the fundamental mode HE11 both inside and outside the nanofiber core. Our findings reveal that the fluorophosphate (S-FPM3) nanofiber exhibits a dominant Kerr 2024-02-01

The nanofiber materials of three-dimensional spatial structure synthesized by electrospun have the characteristics of high porosity, high specific surface area, and high similarity to the natural extracellular matrix (ECM) of the human body. These are beneficial for absorbing wound exudate, effectively blocking the invasion of external bacteria, and promoting cell respiration and proliferation, which provides an ideal microenvironment for wound healing. Moreover, electrospun nanofiber dressings can flexibly load drugs according to the condition of the wound, further promoting wound healing. Recently, electrospun nanofiber materials have shown promising application prospects as medical 2024-09-01

Green polymers and nanocomposites are noticed by researchers in the environmental fields. Among them, starch, polylactic acid, and cellulose nanofiber (CNF) are eco-friendly. In the present study, thermoplastic bio-nanocomposites of starch/cellulose nanofiber (SN), polylactic acid/cellulose nanofiber (PN), and starch/polylactic acid/cellulose nanofiber (SPN) are prepared by film casting. The effect of nanofibers is investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), mechanical properties, and water vapor permeability (WVP) of films. Results show that the mechanical properties of SN and PN improve with the addition of CNFs due to their uniform dispersion which are 2024-10-01
