Green biosynthesis of magnetic iron oxide nanoparticles using Mentha longifolia for imatinib mesylate delivery

Abstract

In this work, the rapid, facile, and eco‐friendly green process was introduced in the preparation of β ‐cyclodextrin/magnetic iron oxide nanoparticles by using the aqueous Mentha longifolia extracts of Mentha longifolia . The obtained nanoparticles were characterised by Fourier transform infrared spectroscopy, x‐ray powder diffraction, field emission scanning electron microscope, and thermogravimetric analysis. Also, effective factors on the synthesis of magnetic nanocomposites including temperature, concentration of the Mentha longifolia extract, and concentration of FeSO 4 solution were optimised by Taguchi design. Moreover, important effective parameters on the adsorption efficiency; such as adsorbent dosage, pH, contact time, and temperature were investigated. The prepared magnetic nanocomposite was applied as a nanocarrier for imatinib mesylate delivery. In vitro studies confirmed imatinib mesylate release over 6 h. The nanocarrier showed pH‐dependent imatinib mesylate release with higher drug release at simulated cancer fluid (pH = 5.6) compared to neural fluid (pH = 7.4). Moreover, the sorption isotherms and kinetics for the magnetic nanocomposite were fitted into Langmuir and pseudo‐second order models, respectively. Based on the thermodynamic results, the adsorption of imatinib mesylate onto the nanoadsorbent was found to be spontaneous and exothermic.

Mentha longifolia assisted nanostructures: An approach to obliterate microbial biofilms

“…According to research conducted by Rao et al ., [ 18 ], the key advantage of using plants for the synthesis of nanoparticles is that they are biosafe, simple to use, and contain a diverse range of metabolites involved in the ion reduction procedure. Nanoparticle synthesis via physical and chemical synthetic approaches is extremely expensive, but this cost can be significantly reduced by using natural herbs in the synthesis process [ 19 ].…”
