Targeted drug delivery by magnetic nanoparticles (MNPs) is at the leading edge of the rapidly developed methods for the diagnosis and treatment of various diseases. Functionalization of nonsteroidal anti‐inflammatory drugs (NSAIDs) onto MNP‐based platforms constitutes a challenging endeavor, as it is based on the physicochemical characteristics of the final carrier/system. MnFe2O4 MNPs of relatively
通过磁性纳米颗粒(MNP)靶向药物递送是快速发展的各种疾病的诊断和治疗方法的前沿。非甾体类抗炎药(NSAID)在基于MNP的平台上的功能化是一项具有挑战性的工作,因为它基于最终载体/系统的理化特性。锰铁2 O 4在十八烷基胺(ODA)存在下,通过合成变化溶剂热法制备了尺寸相对较小且具有胺化(AmMNPs)和非胺化(Non-AmMNPs)表面的磁化强度增强的MNP。三种具有不同药理特性的非甾体类抗炎药(NSAIDs),乙酰水杨酸(ASA),甲芬那酸(MEF)和萘普生(NAP)用于装载纳米平台。在AmMNP的情况下,NSAID的连接是通过羧酸盐供体与NH 2的直接偶联实现的通过形成酰胺键形成基团,而利用PEG化方法将药物通过包封间接偶联到Non-AmMNPs上。FT-IR和UV / Vis数据证实了独特的药物释放行为,这归因于不同的交联力,具体取决于功能化方法。对MNPs @ NSAIDs的生
