提出了一种新的两步种子聚合法制备核/壳结构的AFDFM。通过透射电镜和扫描电镜对其形貌进行了表征，并利用红外光谱、荧光显微镜、激光共聚焦荧光显微镜和荧光光谱对其进行了表征。TEM和SEM图像提供了核/壳结构的明确证据。荧光光谱表明，AFDFM表现出可调谐的荧光特性与一个或两个发射波长（515和575 nm）取决于激发波长。AFDFM壳层上的酰胺基和羧基允许与生物分子形成连接，用于生物成像或分子检测，为生物医学应用开辟了机会。
A novel two-step modified seeded polymerization method for the preparation of AFDFMs with a core/shell structure is developed. Their morphology is characterized by means of TEM and SEM, further characteristics are studied using FT-IR, fluorescence microscopy, laser confocal fluorescence microscopy, and fluorescence spectroscopy. TEM and SEM images provide clear proof of a core/shell structure. Fluorescence spectroscopy shows that AFDFMs exhibit tunable fluorescence characteristics with one or two emission wavelengths (515 and 575 nm) depending on the excitation wavelengths. Amido and carboxy groups on the AFDFM shell layer allow the formation of linkages with biomolecules for biological imaging or molecule detection, opening opportunities for biomedical applications.
