Abstract
Implementing new methods to prepare magnetite nanoparticles with a covered or uncovered surface has been, and still is, a significant challenge. In this work, we describe a very clear and effortless way for the preparation of magnetite nanoparticles using two types of bases, namely: 1-(3-aminopropyl)imidazole and sodium hydroxide. Fourier transform infrared spectroscopy (FTIR) served as a tool for the structural investigation of the as-prepared magnetite nanoparticles. The morphology of the samples was investigated using Transmission Electron Microscopy (TEM). Comprehensive high-resolution X-ray photoelectron spectroscopy investigations (XPS) were applied as an effective tool for analyzing the composition of the various types of magnetic nanoparticles. Further polymer linkage was accomplished with poly(benzofuran-co-arylacetic acid) on the amino-functionalized surface of aminopropylimidazole-containing magnetic nanoparticles. The findings are promising for biomedicine, catalysis, and nanotechnology applications.
Highlights
Served as a tool for the structural investigation of the as-prepared magnetite nanoparticles
Source can be applied in the straightforward synthesis of functionalized magnetite nanoparticles magnetic nanoparticles (MNP)-AIm when AIm, as a stabilizer, is used
A remarkably straightforward synthesis of functionalized MNP was found by treating aqueous solutions of FeCl2 with 1-(3-aminopropyl)imidazole in the air at room temperature
Summary
Served as a tool for the structural investigation of the as-prepared magnetite nanoparticles. The nanosized iron oxide is a massively promising nanomaterial already used in a wide array of diverse applications, such as catalysis [1,2,3], adsorbent material of pollutants [4,5,6], sensing [7,8], optics [9], drug delivery, and cancer diagnosis and treatment [10,11,12,13] In this case, the implementation significantly depends on the shape and size of the nanoparticles. The technology starting with Fe(II) was not employed for 1-(3-aminopropyl)-imidazole (AIm) as a stabilizer or in combination with sodium hydroxide, neither at an elevated temperature nor at room temperature, and is followed up in the present work
