Abstract We discuss ways of an improvement of the analytic technique for characterization of magnetic nanoparticles and their chemical transformation to ferritin-like forms after their injection in a living organism by means of measuring and analyzing the Mossbauer spectra and magnetization curves. This is based first on the theoretical achievements in developing models of magnetic dynamics of antiferromagnetic nanoparticles for describing thermodynamic properties of ferritin and related proteins. Generalization of the approach for ferrimagnetic nanoparticles allows one to take directly into account the magnetic nature of nanoparticles in analyzing the corresponding experimental data. Another way is to extend this technique with measuring and analyzing non-equilibrium magnetization curves (hysteresis loops) which allows one to more reliably evaluate time changes in the residual nanoparticles and iron-containing proteins characteristics during biodegradation.

用于表征来自穆斯堡尔和磁化测量的体内纳米颗粒生物降解的新型磁动力学模型

摘要 我们通过测量和分析 Mossbauer 光谱和磁化曲线,讨论了改进表征磁性纳米粒子的分析技术及其在将其注入生物体后化学转化为铁蛋白样形式的方法。这首先基于在开发反铁磁纳米粒子的磁动力学模型以描述铁蛋白和相关蛋白质的热力学特性方面的理论成就。亚铁磁性纳米粒子方法的推广允许人们在分析相应的实验数据时直接考虑纳米粒子的磁性。
