研究目的
Investigating the application of fluorescent nanodiamonds (FNDs) in cell labeling and fluorescence imaging for biomedical studies.
研究成果
The research demonstrates that FNDs are a promising nanoparticle platform for biomedical applications, particularly in cell labeling and fluorescence imaging. Their unique properties, such as high biocompatibility, low cytotoxicity, and superior photostability, make them ideal for tracking and imaging cells in vitro and potentially in vivo. The study opens up new avenues for diagnostic and therapeutic applications, though further optimization and research are needed to overcome current limitations.
研究不足
The study acknowledges the aggregation problem of FNDs in certain mediums and the potential interference of large protein molecules like BSA in specific labeling processes. The photophysical properties of FNDs, while advantageous, also present challenges in terms of excitation and detection methodologies.

The study focuses on the use of FNDs for cell labeling and imaging, leveraging their superior magneto‐optical properties, ability to be functionalized with diversified bioactive groups, inherent biocompatibility, and high sensitivity detection at the single particle level.
2：Sample Selection and Data Sources:
Various cell lines and primary cells were used, including HeLa cells, HepG2 cells, and mesenchymal stem cells, among others.
3：List of Experimental Equipment and Materials:
Equipment includes fluorescence microscopy, confocal fluorescence microscopy, total internal reflection fluorescence microscopy (TIRFM), and two‐photon excitation (TPE) microscopy. Materials include FNDs, bovine serum albumin (BSA), poly‐l‐lysine (PLL), and various bioactive molecules for surface functionalization.
4：Experimental Procedures and Operational Workflow:
The process involves labeling cells with FNDs, either specifically or nonspecifically, followed by fluorescence imaging using various microscopy techniques to track and analyze the cells.
5：Data Analysis Methods:
Flow cytometric analysis was used to quantify the uptake of FNDs by cells, and fluorescence imaging techniques were employed to visualize the distribution and behavior of FND-labeled cells.
