Superparamagnetic calcium ferrite nanoparticles synthesized using a simple sol-gel method for targeted drug delivery

Abstract

Abstract. The calcium ferrite nano-particles (CaFe 2 O 4 NPs) were synthesized using a sol-gel method for targeted drug delivery application. The proposed nano-particles were initially prepared by mixing calcium and iron nitrates that were added with citric acid in order to prevent agglomeration and subsequently calcined at a temperature of 550ÛC to obtain small particle size. The prepared nanoparticles were characterized by using an XRD (X-ray diffraction), which revealed the configuration of orthorhombic structures of the CaFe 2 O 4 nano-particles. A crystallite size of ~13.59 nm was obtained using a Scherer's formula. Magnetic analysis using a VSM (Vibrating Sample Magnetometer analysis), revealed that the synthesized particles exhibited super-paramagnetic behavior having magnetization saturation of approximately 88.3emu/g. Detailed observation via the scanning electron microscopy (SEM) showed the calcium ferrite nano-particles were spherical in shape.

Shape Anisotropic Iron Oxide-Based Magnetic Nanoparticles: Synthesis and Biomedical Applications

“…The general structure of a normal spinel structure can be written as (Me 2+ )[Fe 3+ 2 ]O 4 , where Me +2 refers to divalent cations, occupying tetrahedral positions, and Fe 3+ serving as trivalent cations, occupying octahedral positions [7,8]. Given their unique structural and magnetic properties, ferrite nanoparticles have been widely used for magnetic drug delivery [9][10][11], magnetic hyperthermia [12][13][14] and magnetic resonance imaging [15][16][17]. Research on preparation methods and characterization of different anisotropic shapes of these nanoparticles is important and it is recently increasing, since desired physicochemical properties and applications can be achieved by simply change structural parameters [18][19][20][21][22].…”

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

“…In view of factors such as biocompatibility and nontoxicity, ferrites of calcium have emerged as sustainable alternative. Ca─Fe based catalysts being chemically and thermally stable, environmentally safe, and inexpensive option have been reported as photocatalysts, drug delivery devices, catalysts for oxidation and esterification reactions and hydrogen production …”

Soft nanoimprint lithography on SiO2 sol-gel to elaborate sensitive substrates for SERS detection

“…These mechanisms are based on the transformation of a liquid solution (sol) into a solid material (a dry gel called xerogel) via an inorganic polymerization process. Then sol-gel thin film can be stabilized and cured either by annealing 31,32 to permit the evaporation of residual solvent still present inside the xerogel thin film or by photocuring. 33 The interest to use such inorganic polymers as material for nanoimprint lithography has been growing over the last decade.…”
