Multiscale Control of Nanofiber-Composite Hydrogel for Complex 3D Cell Culture by Extracellular Matrix Composition and 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

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

Nanofiber core-spun yarn (NCSY) combines the advantages of traditional fibers and nanofibers to be widely used in smart wearable textiles, biomedical textiles, and functional textiles. Here, for the first time, the forming process of NCSY and its shape regulation mechanism were explored via finite element analysis and response surface analysis method to obtain mathematical model for predicting the various forms of yarn. As proof-of-concept applications, shape-controllable nanofiber core-spun yarns were prepared for thermal–moisture management and solar steam generation, respectively. The as-obtained shape-controllable PAN nanofiber/cotton composite yarns could achieve an interval control of 2024-04-01

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
