“…This showed that the addition of SeNPs causes interactions between SeNPs and the polymeric matrix. [ 51 ] This is consistent with the DSC results. The Se 3d (61.7 eV) peak in the XPS spectrum of OD‐PP@SeNPs hydrogel indicated that SeNPs were successfully added to the hydrogel system (Figure 1N ).…”

Modulating the inflammatory microenvironment can inhibit the process of inflammatory diseases (IDs). A tri‐cross‐linked inflammatory microenvironment‐responsive hydrogel with ideal mechanical properties achieves triggerable and sustained drug delivery and regulates the inflammatory microenvironment. Here, this study develops an inflammatory microenvironment‐responsive hydrogel (OD‐PP@SeNPs) composed of phenylboronic acid grafted polylysine (PP), oxidized dextran (OD), and selenium nanoparticles (SeNPs). The introduction of SeNPs as initiators and nano‐fillers into the hydrogel results in extra cross‐linking of the polymer network through hydrogen bonding. Based on Schiff base bonds, Phenylboronate ester bonds, and hydrogen bonds, a reactive oxygen species (ROS)/pH dual responsive hydrogel with a triple‐network is achieved. The hydrogel has injectable, self‐healing, adhesion, outstanding flexibility, suitable swelling capacity, optimal biodegradability, excellent stimuli‐responsive active substance release performance, and prominent biocompatibility. Most importantly, the hydrogel with ROS scavenging and pH‐regulating ability protects cells from oxidative stress and induces macrophages into M2 polarization to reduce inflammatory cytokines through PI3K/AKT/NF‐κB and MAPK pathways, exerting anti‐inflammatory effects and reshaping the inflammatory microenvironment, thereby effectively treating typical IDs, including S. aureus infected wound and rheumatoid arthritis in rats. In conclusion, this dynamically responsive injectable hydrogel with a triple‐network structure provides an effective strategy to treat IDs, holding great promise in clinical application.

“…This is after which the TiO 2 nanoparticles release reactive species through interaction with the inert environment of the cells. The produced radicals caused the destruction of bacterial cells due to their decomposition and complete degradation of microorganisms [ 27 , 28 , 29 ]. These findings demonstrated that PEO/CMC/TiO 2 NPs films could serve as a viable substitute for their synthetic equivalents in the food packaging sector.…”

In this article, the synthesis, optical, and electrical properties of composites consisting of polyethylene oxide (PEO), carboxymethyl cellulose (CMC), and titanium dioxide nanoparticles are examined. Flexible nanocomposite samples comprising PEO, CMC, and TiO2 nanoparticles were produced swiftly via using the cast synthesis method. In addition, XRD and FT-IR analysis were performed in order to analyze the structures of the prepared samples. Our results demonstrate the PEO/CMC blend’s effectiveness in interacting with TiO2 nanoparticles. The optical properties of the PEO/CMC and nanocomposite samples, such as the energy band gap, were studied using the UV/Vis optical absorbance. It was found that as TiO2 NP weight fraction increases, the energy gap narrows. Moreover, TiO2 nanoparticles with an average size of 16 nm were formed in spherical and rod shapes, according to a TEM image. The SEM images demonstrate how the distribution of TiO2 NPs increased upon the surfaces of the prepared films. The antibacterial activity in the nanocomposites was shown to be enhanced by the TiO2 NP concentrations. Finally, we proposed that PEO/CMC-0.8 wt. % TiO2 nanocomposites with enhanced optical, electrical, and dielectric properties should be used in electrochemical devices.

Polymer nanocomposite samples of a polyvinyl alcohol (PVA)/carboxymethyl cellulose (CMC) blend doped with copper nanoparticles and selenium nanoparticles (Cu NPs/Se NPs) were prepared by the casting method. X-ray diffraction analysis (XRD) patterns showed an increase in the degree of amorphous nature of the host polymeric matrix with increasing content of Cu/Se nanoparticles. The addition of 1.60 wt.%, Cu/Se NPs narrowed the indirect optical energy gap value of the nanocomposite from 3.97 to 2.39 eV. In addition, the differential scanning calorimetry (DSC) curve of the pure blend displays the miscibility of the blend components, confirmed by the presence of a single glass transition. Transmission electron microscopy (TEM) micrographs showed that the average sizes of Cu and Se nanoparticles are about 11 and 41 nm, respectively. The maximum values of AC and DC conductivity were 6.76 Â 10 À6 S.cm À1 and 5.49 Â 10 À10 for a PVA/CMC film filled with 1.60 wt.% of Cu-Se NPs. The mechanical properties of the PVA/CMC blend improved after adding the hybrid NPs. Moreover, the antibacterial activity of the prepared samples was increased due to the filling of Cu-Se nanoparticles to the films. Therefore, these results indicate the multifunctionality of PVA/CMC/Cu-Se nanocomposite samples for use in electrical energy storage, solid-polymer electrolytes, and food packaging industry.
