Synthesis, characterization and evaluation of the toxicity, drug release ability and antibacterial capacity of nanocomposites of polyethylene glycol and functionalized carbon nanotubes

Synthesis and Evaluation of Antifungal and Antibacterial Abilities of Carbon Nanotubes Grafted to Poly(2-hydroxyethyl methacrylate) Nanocomposites

“…In this sense, this nanofiller acted as an agent that produced a constraint effect on the dynamics of the polymer chains of PHEMA. In a previous study by our research group, similar results were found for nanocomposites prepared with polyethylene glycol and CNTs functionalized with amine groups [25].…”

“…Additionally, the chemical functionalization with –NH 2 , –COOH, and –OH groups of the purified CNTs was carried out following an experimental procedure of three steps. Both procedures were developed and used by our research group previously, as reported elsewhere [ 25 ]. The experimental procedure used to functionalize the purified CNTs (named CNTs pu ) is summarized below.…”

“…The components and their atomic concentrations were C-C/C-H bonds at 285.0 eV [31] Moreover, the C1s core-level normalized spectrum of Na 1 also showed components at five positions. These components and their atomic concentrations were C-C/C-H bonds at 285.0 eV [31] (29.8%), C-C=O bonds at 285.7 eV [31] (14.6%), C-OH bonds at 286.7 eV [31] (8.0%), C-O-C [25]/HN-C=O bonds [26,27,32,33] at 287.2 eV (7.2%), and O-C=O bonds at 289.3 eV [31] (6.9%). It is evident that the atomic concentration of the C-OH bonds detected in the spectrum of Na 1 decreased with respect to that observed in the spectrum of pure PHEMA.…”

Screening of low‐toxic zinc oxide nanomaterials and study the apoptosis mechanism of NSC‐34 cells

“…These disturbances are caused by alterations in the structure, permeability, and transport activity of the membrane. [19,[21][22][23] 3D Nanoflowers are a recently developed type of nanomaterials that show great potential in the rapid and accurate detection of diseases like Parkinson's disease and Alzheimer's disease.…”

“…Additionally, nanorods and nanosheets contribute to cell death mediated by oxidative stress, involving both ROS-dependent and ROS-independent mechanisms. [13][14][15][16][17][18][19][20][21][22][23] The cytotoxicity of ZnO-NMts has been demonstrated in both in vitro and in vivo studies using various mammalian cells. Different levels of toxicity have been observed on human A549 cells, human gingiva cells, zebrafish cells, HepG2 cells, and human endothelial cells.…”
