二次离子质谱生物成像

Bioimaging By Secondary Ion Mass Spectrometry

二次离子质谱作为目前空间分辨率最高的质谱成像技术,以其免标记、高灵敏、多组分检测优势和亚微米级高空间分辨成像优势为诸多生命科学问题的研究提供了全新的分析手段,在基础细胞生物学、组织生理病理学、生物医药与临床医学等领域的研究中得到了广泛应用。本文综述了二次离子质谱在生物组织、细胞、仿生生物膜等体系中的质谱成像研究进展。

Secondary ion mass spectrometry(SIMS), as the highest spatial resolution mass spectrometry imaging technique, holds label-free, high sensitivity, multi-component detection advantages and sub-micron high spatial resolution imaging advantage, providing new analysis method to study life science problems. SIMS has been widely used in cell biology, tissue pathological physiology, biological medicine, clinical medicine and other fields. This paper reviews the progress of SIMS imaging in biological tissue, cell, bionic biofilm and other bio-samples.
