However, its low aqueous dispersity with severe emission quenching has limited its biological application. Herein, chlorophyll-derived CDs from mulberry leaf (MCDs) have been successfully coated with polyethylenimine (PEI) via a simple and mild solution-mixing method at room temperature. Experimental optimization proved that the MCDs produced at a reaction temperature of 120 °C and a reaction time of 4 h had the best PL strength, while the PEI-MCDs produced at a PEI/CDs ratio of 0.4 ‰ had the best PL strength. The PEI-MCDs composites demonstrate good aqueous dispersity and exceptional fluorescence stability under various conditions like UV irradiation, temperature fluctuations, salt and various substances. A strong narrow-band deep-red emission at 670 nm with quantum yield (QY) of 45.44 % is obtained in PEI-MCDs aqueous solution. The mechanism of lipophilic-hydrophilic transformation and emission recovery in aqueous solution is confirmed to be the amphiphilicity shell of PEI on MCDs, which effectively improves the aqueous dispersity and suppresses the occurrence of aggregation-caused quenching. Selective imaging of lysosomes in various cells has been realized by utilized PEI-MCDs without targeting ligands. Furthermore, clear tissue structures were shown in the in vivo fluorescence imaging of zebrafish embryos and larvae. The results indicate PEI-MCDs own notable amphiphilicity, superior stability and excellent deep-red emission, which hold great promise for biological imaging applications.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"239 ","pages":"Article 112799"},"PeriodicalIF":4.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, organic small-molecule fluorescent probes have gained widespread application in LD imaging due to their simple structure, ease of operation, and good biocompatibility. This review summarizes recent advances in organic small-molecule fluorescent probes for bioimaging LD-related diseases, focusing on design strategies, optical properties, biological applications, and current challenges. Furthermore, we discuss future directions in this field, including the development of novel probes with higher specificity, sensitivity, in vivo stability, and deep tissue penetration capabilities.

In this study, A carrier-free rigid fluorescent small molecule CF<sub>3</sub>/S-containing BODIPY probe (BODIPY-CF<sub>3</sub>/S) was designed and synthesized by introducing benzothiophene groups and trifluoromethane groups into the probe structure. By using the benzene ring large conjugate system to modify the parent structure of BODIPY, a rigid conjugate structure with large π-bonds was formed, improving the photophysical characteristics, increasing the fluorescence wavelength, and improving the intensity and stability of the fluorescence emission. The introduction of benzene ring system and trifluoromethane group makes the probe have good fat solubility. Solvent evaporation was used to create single crystals, and the rigid large conjugate structure of the crystals was seen. Following testing, the probe's photophysical characteristics at various pH values held up well and were largely stable. The BODIPY-CF<sub>3</sub>/S fluorescent marker exhibits good biocompatibility with both HCT-116 and HeLa tumor cells, and can enter the cell interior without any carrier due to its excellent fat solubility. Its ability to emit a distinct green fluorescent signal makes it useful for follow-up observation and visualization. As such, it has potential applications as a fluorescent marker. In addition, in vitro cytotoxicity studies, the probe showed good inhibition on A549 cancer cells and HCT-116 cancer cells. In summary, the prepared BODIPY-CF<sub>3</sub>/S fluorescent probe has the advantages of long wavelength, strong conjugation stability, good photophysical quality, no carrier and strong fat solubility. These attributes will give researchers and designers of BODIPY rigid conjugated fluorescent probes new ideas for their future research and development.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"239 ","pages":"Article 112791"},"PeriodicalIF":4.1,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
