NMR（Nuclear－Magnetic－Resonance）为核磁共振的应用介绍
核磁共振适合于液体、固体。如今的高分辨技术,还将核磁用于了半固体及微量样品的研究。核磁谱图已经从过去的一维谱图(1D)发展到如今的二维(2D)、三维(3D)甚至四维(4D)谱图,陈旧的实验方法被放弃,新的实验方法迅速发展,它们将分子结构和分子间的关系表现得更加清晰。在世界的许多大学、研究机构和企业集
链霉亲和素磁珠（SA－magnetic－bead）性能比较研究
磁性聚合物微球兼具高分子微球特性和磁响应性，因此，广泛应用于靶向给药、生物诊断、催化剂制备、磁成像等领域。目前，大部分的生物分子是通过表面的氨基或者羧基与磁性微球表面的基团共价结合的方式直接固定化在磁性微球的表面。这种方法不仅复杂，还会使固定化的生物分子活性受到较大影响，例如抗体可能会失去与抗原的特
