BACKGROUND Graphene and graphene-based nanocomposites are used in various research areas including sensing, energy storage, and catalysis. The mechanical, thermal, electrical, and biological properties render graphene-based nanocomposites of metallic nanoparticles useful for several biomedical applications. Epithelial ovarian carcinoma is the fifth most deadly cancer in women; most tumors initi...
Background and purpose: The use of bioactive glass-ceramics in medicine has been noticed because of their ability in directly connection to bony tissue and bone repairing. Chitosan is also nontoxic material and biologically is compatible with the capability of biodegradation. However, due to the minimally invasive nature of injectable systems and their ability to make scaffold in place of using...
The unique properties and applications of iron oxide and Au nanoparticles have motivated researchers to synthesize and optimize a combined nanocomposite containing both. By using various polymers such as chitosan, some of the problems of classic core-shell structures (such as reduced saturation magnetization and thick coating) have been overcome. In the present study, chitosan and one of its we...
This work describes the synthesis and characterization of noncytotoxic nanocomposites either colloidal or as films exhibiting high antibacterial activity. The biocompatible and biodegradable polymer chitosan was used as reducing and stabilizing agent for the synthesis of gold nanoparticles embedded in it. Herein, for the first time, three different chitosan grades varying in the average molecul...
Background and purpose: This study compared the effects of intraperitoneal injections of ZnO/chitosan nanocomposite and ZnO nanoparticles on histopathology of kidney in thioacetamide-intoxicated rats. Materials and methods: Twenty-eight male rats were randomly allocated into a healthy control group (negative control), positive control group (thioacetamide-intoxicated rats), thioacetamide-into...
Wearable electronics used in smart clothing for healthcare monitoring or personalized identification is a new and fast-growing research topic. The challenge is that the electronics has to be simultaneously highly stretchable, mechanically robust and water-washable, which is unreachable for traditional electronics or previously reported stretchable electronics. Herein we report the wearable elec...
Evaluation of Schiff base nanocomposite hydrogels properties using a benzaldehyde multifunctional amphiphilic polyacrylamide crosslinker in conjunction with glycol chitosan.
Background & Aims: Zeolite has skin wound healing capacity. However, its efficacy on burn wound healing has not yet been examined. In this study, we investigated the effects of Zeolite-Ag+/Gelatin nanocomposite on the process of third-degree burn wound healing in mice model. Materials & Methods: Ag+- zeolite/gelatin nanocomposite was fabricated by sol-gel method; MTT assay and antimicrobial ac...
Bioactivity investigations of titania nanotube (TNT) coatings enriched with silver nanograins (TNT/Ag) have been carried out. TNT/Ag nanocomposite materials were produced by combining the electrochemical anodization and chemical vapor deposition methods. Fabricated coatings were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. ...
Montmorillonite modified with a quaternary ammonium salt C30B/starch nanocomposite (C30B/ST-NC), silver nanoparticles/starch nanocomposite (Ag-NPs/ST-NC) and both silver nanoparticles/C30B/starch nanocomposites (Ag-NPs/C30B/ST-NC) films were produced. The nanoclay (C30B) was dispersed in a starch solution using an ultrasonic probe. Different concentrations of Ag-NPs (0.3, 0.5, 0.8 and 1.0mM) we...
