Fabrication and characterization of biopolymers with antibacterial nanoparticles and Calendula officinalis flower extract as an active ingredient for modern hydrogel wound dressings

Preparation and characterization of doped hollow carbon spherical nanostructures with nickel and cobalt metals and their catalysis for the green synthesis of pyridopyrimidines

“…In the first step, SiO 2 spheres were prepared from tetraethyl orthosilicate with the Stöber method. 33 Then, the SiO 2 spheres were coated with glucose, cobalt, and nickel through the hydrothermal method. Finally, the Co-Ni@HCSs were prepared by etching SiO 2 spheres with concentrated sodium hydroxide.…”

Nanomaterials-Functionalized Hydrogels for the Treatment of Cutaneous Wounds

“…Furthermore, Ag oxides have also been proven to have antibacterial activity. Mohammadimehr et al loaded Ag 2 O/SiO 2 and calendula officinalis flower extract in a CS/sodium alginate (SA)/PVA hydrogel, which showed great antibacterial activity and potential to promote wound healing [90]. Besides, various types of composite hydrogels employing Ag NPs in synergy with other types of NMs as antimicrobial components have been reported, such as Ag NPs combined with g-C 3 N 4 /TiO 2 [91], melatonin [92], and GO [86].…”

Fabrication and characterization of inorganic–organic hybrid copper ferrite anchored on chitosan Schiff base as a reusable green catalyst for the synthesis of indeno[1,2-b]indolone derivatives

“…24 Also, these compounds have biological activities. 25 In continuation of our ongoing research works on catalytic reactions, [26][27][28][29][30][31] in this work, we chose to look into the straightforward and efficient synthesis of indeno [1,2-b]indolones utilizing a novel effective heterogeneous nanocatalyst. Initially, copper ferrite nanoparticles were prepared by the coprecipitation method; then, the magnetic nanoparticles of the CuFe 2 O 4 @CS-SB nanocomposite were prepared by chelating on the surface of chitosan and a Schiff base.…”
