Abstract

An ensemble of nanosystems can be considered to improve magnetic resonance imaging (MRI) transverse relaxivity. Herein, an interacting superparamagnetic competing structure of an isotropic-anisotropic trimagnetic hybrid nanosystem, γ-Fe₂O₃@δ-MnO₂@NiFe₂O₄, is considered for MRI relaxivity exploration. The interacting superparamagnetic system reveals fascinating dynamic magnetic behavior, where flower-shaped two-dimensional flakes are decorated over nanoparticles. The hybrid nanosystem exhibits modulated shape anisotropy with spin blocking and energy barrier broadening, which help in achieving faster MR transverse relaxivity. The hierarchical architecture ensemble of the trimagnetic landscape shows effective MR transverse relaxivity with a transverse (r₂)/longitudinal (r₁) relaxivity of 61.5 and potential cell viability. The competing trimagnetic system with regulated activation energy is found to be the underlying reason for such signal enhancement in MRI contrast efficiency. Hence, this study displays a novel pathway correlating MR transverse relaxivity with dynamic magnetic behavior and competing landscape of hierarchical trimagnetic ensembles.

用于增强磁共振横向弛豫的相互作用三磁性组合体

纳米系统的组合可用于提高磁共振成像（MRI）的横向弛豫性。在此，我们考虑了各向同性-各向异性三磁混合纳米系统（γ-Fe2O3@δ-MnO2@NiFe2O4）的相互作用超顺磁性竞争结构，以探索磁共振成像的弛豫性。这种相互作用的超顺磁性系统显示出迷人的动态磁性行为，纳米粒子上装饰着花形的二维薄片。这种混合纳米系统表现出具有自旋阻滞和能障增宽的调制形状各向异性，有助于获得更快的磁共振横向弛豫性。三磁景观的分层结构组合显示出有效的磁共振横向弛豫性，横向（r2）/纵向（r1）弛豫性为 61.5，具有潜在的细胞活力。研究发现，具有调节活化能的竞争三磁性系统是磁共振成像对比效率信号增强的根本原因。因此，这项研究展示了一种新的途径，将磁共振横向弛豫度与动态磁行为和分层三磁性组合的竞争景观联系起来。
