Chitosan/Gamma-Alumina/Fe3O4@5-FU Nanostructures as Promising Nanocarriers: Physiochemical Characterization and Toxicity Activity

“…The peak at 887 cm −1 is assigned to out-of-plane bending of the C–H bond of the monosaccharide ring. The peaks appearing at 1020 cm −1 and 1060 cm −1 can be assigned to tensile vibration of the C–O bond, in agreement with the spectra recorded in previous articles [ 90 , 91 , 92 , 93 , 94 ]. The peak near 1320 cm −1 is attributed to the C–N tensile vibration of the ternary amide bond, which is consistent with the results from other articles [ 95 ].…”

ZnFe2O4 Magnetic Nanoparticle–Polydiacetylene–Zinc(II) Composites for Real-Time Nanothermometers and Localizable Acid/Base Sensors

“…Materials with high magnetism such as pure metals (e.g., cobalt, nickel, and iron), alloys (e.g., CoPt and FePt), and metal oxides (e.g., Fe 3 O 4 , Co 3 O 4 , and NiO) have the potential to be produced as magnetic nanoparticles (MNPs). , Iron oxides such as magnetite (Fe 3 O 4 ) and maghemite (γ-Fe 2 O 3 ) are some of the most studied MNPs because of their high chemical stability, biocompatibility, and low cost. , They have been applied as diagnostic [e.g., as a contrast agent for magnetic resonance imaging (MRI)] and therapeutic (e.g., drug delivery and hyperthermia) agents. − In addition, the strong reducing property, high surface-to-volume ratio, and surface modification allow utilization of these materials as nanosorbents and photocatalysts. , Iron oxide MNPs have been incorporated in various polymeric matrices and other materials to produce magnetic nanocomposites (MNCs). − This class of materials has shown potential in various applications such as sensors, cancer therapy, drug delivery, anticounterfeiting materials, anticorrosion coatings, flame retardants, and UV protectors …”

“…12,13 Iron oxide MNPs have been incorporated in various polymeric matrices and other materials to produce magnetic nanocomposites (MNCs). 14−22 This class of materials has shown potential in various applications such as sensors, 16 cancer therapy, 17 drug delivery, 18 anticounterfeiting materials, 19 anticorrosion coatings, 20 flame retardants, 21 and UV protectors. 22 Recently, the fabrication and use of PDA/Fe 3 O 4 -MNCs have been explored.…”

Optimization of Naringenin Nanoparticles to Improve the Antitussive Effects on Post-Infectious Cough

“…Many biosafe and biodegradable materials have been utilized as nanocarriers to prepare the nanodelivery system for NRG, in particular, chitosan [21,22], cyclodextrin [23,24], polylactic acid [25,26], polylactic acid/glycolic acid copolymer [27,28], polycaprolactone [29,30], poly(vinylpyrrolidone) [31], and tocopheryl polyethylene glycol succinate (TPGS) [32,33]. Among them, TPGS has been utilized broadly as a nanocarrier to encapsulate NRG, because of its excellent amphiphilic properties, entrapment efficacy, and biosafety [34,35].…”
