Problems solved by technology

[0002] The research of biological macromolecules by fluorescence technology (such as protein conformation, DNA separation and sequencing, etc.), the in situ research of cell growth, apoptosis, and mutation have so far mainly focused on the introduction of small molecule fluorescent probes into the research system. Although this method is simple, fast and sensitive, some small molecular fluorescent probes are non-water-soluble and may cause some side effects (such as inducing carcinogenesis), and it is difficult to optimize the required additives (such as surfactants) and poor repeatability, which limits its application in life sciences, medicine and other fields
