Highly biocompatible chitosan with super paramagnetic calcium ferrite (CaFe2O4) nanoparticle for the release of ampicillin

Greener route for microwave enhanced syntheses of bioactive 1,5‐benzodiazepines using heterogeneous calcium ferrite/graphene oxide nanocomposite as a novel and sustainable catalyst

“…The TG curve (Figure ) shows a 12.8% loss of weight up to 200°C due to evaporation of peripheral water and volatile impurities and loss of oxygen functional groups in graphene oxide . A weight loss of 15.8% in the temperature range from 200°C to 700°C was attributed to complete crystallization of cubic spinel phase of calcium ferrite, oxidative decomposition of carbon atoms of GO, loss of lattice water and crystallization of orthorhombic phase of calcium ferrite . Further a sharp weight loss of 21.4% in the temperature range between 700°C to 900°C was ascribed to decomposition of partially reduced graphene oxide by pyrolysis and rearrangement of carbon framework .…”

“…TGA analysis was performed in the temperature range from 30°C to 900°C (heating rate 10°C/min.). The TG curve (Figure ) shows a 12.8% loss of weight up to 200°C due to evaporation of peripheral water and volatile impurities and loss of oxygen functional groups in graphene oxide . A weight loss of 15.8% in the temperature range from 200°C to 700°C was attributed to complete crystallization of cubic spinel phase of calcium ferrite, oxidative decomposition of carbon atoms of GO, loss of lattice water and crystallization of orthorhombic phase of calcium ferrite .…”

Polypyrrole-Chitosan-CaFe2O4 Layer Sensor for Detection of Anionic and Cationic Dye Using Surface Plasmon Resonance

“…Magnetic nanoparticles including CaFe 2 O 4 NPs have superparamagnetic nature in the room temperature and they are biocompatible; hence, they have high potential to use in sensor and biosensor application and they used to detect and recognize the wide range of chemical and biochemical molecular including heavy metals, polycyclic aromatic hydrocarbons, enzymes, and tumor cells [27]. Moreover, chitosan has high compatibility with CaFe 2 O 4 nanoparticles for sensor and degradation of toxic chemical and bimolecular [28]. Polypyrrole is a conductive polymer and it can enhance the SPR signal.…”

Sodium Dodecyl Sulphate-Supported Nanocomposite as Drug Carrier System for Controlled Delivery of Ondansetron

“…Widely used nanoparticles include metals, carbon nanotubes, quantum dots, ceramic and magnetic nanoparticles, etc. [ 1 , 2 ]. Nanoparticles, especially polymeric and mesoporous silica nanoparticles, have been investigated widely [ 3 , 4 ].…”

“…Iron-based nanocomposites have received attention as drug carriers due to their enhanced loading capabilities and control over their physicochemical properties. Such nanocomposites not only possess ferromagnetic properties but also display the properties of organic compound which are non-toxic and suitable for biology and medicine applications [ 2 , 15 , 16 ]. These composites can be synthesized by various methods, e.g., sol-gel, chemical precipitation, hydrothermal, micro-emulsion precipitation, surfactant mediated precipitation and electrodeposition, etc.…”
