Hybridization of nanomaterials (NMs) with natural polymers is one of the best techniques to promote their exciting properties. In this way, the main objective of this work was to investigate the efficiency of decoration of the graphene oxide (GO) nano-sheets with tragacanth gum (TG) polysaccharide. To aim this, different approaches were used (with and without ultrasonic treatment) and various tests (XRD, FTIR, Raman, UV-Vis, DLS, Zeta potential, contact angle, AFM, FE-SEM, TEM, and MTT assay) were conducted. Test results indicated that the nano-hybrids were successfully synthesized. Furthermore, our findings represented that, the TG hybridized GO (TG-GO) appreciably enhanced the biocompatibility of GO. Moreover, it was demonstrated that the ultrasonic treatment of TG solution put a remarkable impact on the microstructure, wettability, and also surface charge characteristic of fabricated nano-hybrids and consequently improved the biocompatibility against L929-fibroblast cells.

This study investigates the cytotoxic and biochemical effects of PEGylated graphene oxide sol-gel (SJ-go) nanoparticles, curcumin, and quercetin on BEAS-2B human bronchial epithelial. In this work, a new graphene oxide nanocomposite (SJ-go) was produced using the sol-gel method through a one-step reaction. These hybrid sol-gel systems include graphite, triethyl orthosilicate (TEOS), and polyethylene glycol (PEG) having a molecular weight of 8000 g/mol.

Arterial stiffening is an independent risk factor for cardiovascular diseases, particularly affecting organs with low vascular resistance, such as the brain and kidneys. Pulse wave velocity (PWV) is the clinical gold standard for arterial stiffness assessment; however, conventional equipment requires complex setups and trained operators, limiting real-world and point-of-care monitoring. Here, we introduce a tactile-transparent wearable (TTW) sensor that preserves physicians' tactile pulse palpation abilities while providing quantitative cardiovascular risk assessment by integrating flexible Polydimethylsiloxane (PDMS) electrodes and ultrathin graphene oxide dielectric films.

Developing next-generation anodes with high silicon (Si) contents requires thoughtful embedment of Si particles in protective media, mainly carbonaceous materials. However, it has been challenging to simultaneously realize optimal electrical conduction, structural integrity, and low-cost synthesis for advancing Si-carbon materials. In this work, we addressed these challenges by synthesizing a composite, where commercial Si nanoparticles are embedded in a dual carbon framework via a facile solution mixing and annealing process.

This research provides a constructive approach for developing high-performance polymer nanohybrids toward enhancing optoelectronic properties, fluorogenic viscosity sensing, and metal-free electrocatalytic oxidation of glycerol to value-added organic(s). Herein, reduced graphene oxide (RGO) and mildly oxidized RGO (MRGO) are strategically combined with fluorescent electroactive polymers (FEPs) to develop a promising sustainable metal-free electrocatalytic system suitable for amplifying opto-electrochemical properties, multiplatform sensing capacity, and electrocatalytic efficiency. The optimized polymeric counterpart (FEP2) promotes dual-state emission in the supramolecular network of RGO-/MRGO-incorporated fluorescent electroactive hybrid polymers (RFEHPs/MFEHPs) through physicochemically confined atypical electron-rich -C(═O)NH-/-C(═O)O-/-SOH fluorophores of (hydroxyethyl)methacrylate and 2-acrylamido-2-methylpropane-1-sulfonic acid monomers.

Rapid and precise detection of () is crucial for early diagnosis, treatment of infectious ailments, and controlling outbreaks. Herein, we present a rapid, streamlined, and sensitive method for screening based on a hollow copper/platinum interspersed graphene oxide nanosheets (Cu/Pt-GO)-mediated cascade responsiveness strategy. The Cu/Pt-GO nanozymes were proposed to catalyze the colorless 3,3',5,5'-tetramethylbenzidine (TMB) to colored oxidized TMB (oxTMB) with enhanced SERS signals, achieving colorimetric/SERS dual-model detection.
