随着生物医学的发展,科学研究对生物成像技术和成像分辨率的要求越来越高,纳米技术和材料被越来越多地应用到生物医学领域中来.在细胞和生物组织的成像分析中,纳米金由于其特殊的表面等离子共振特性和优良的生物相容性,常被用作对比剂、靶向载体、增强剂、示踪剂和传感器而广泛应用于生物成像领域中.我们将课题组的研究方向与目前该领域的研究热点相结合,从纳米金辅助细胞及细胞内成像和动物活体成像两个方面就纳米金在生物成像、医学诊断等领域中的应用进展进行了阐述.
With the development of biomedicine, the scientific research on biological imaging technology and imaging resolution is more and more demanding, nanotechnology and materials are increasingly used in the field of biomedicine.In imaging analysis of cells and biological tissues , Nano gold has been widely used in the field of bioimaging due to its special surface plasmon resonance and excellent biocompatibility, which is often used as contrast agent, targeting carrier, enhancer, tracer and sensor.We will The research direction of the research group is combined with the current research hotspot in this field. The application progress of nanometer gold in bioimaging, medical diagnosis and other fields are described from the aspects of nanogold-assisted cells, intracellular imaging and animal living imaging.
