Modelling of magnetoimpedance response of thin film sensitive element in the presence of ferrogel: Next step toward development of biosensor for in-tissue embedded magnetic nanoparticles detection.

组织内嵌磁性纳米颗粒（MNPs）检测是癌症研究中的重要问题。为阐明磁生物传感器检测三维介观分布MNPs时灵敏度的来源、极限及改进途径，作者开发了一种磁阻抗（MI）生物传感器原型，其矩形敏感元件为[Cu(3 nm)/FeNi(100 nm)]5/Cu(500 nm)/[FeNi(100 nm)/Cu(3 nm)]5多层膜。通过测量有无...
