Overview of rhodamine dyes

Rhodamine dyes are a kind of basic xanthene dyes. The basic skeleton of rhodamine compounds is mainly composed of two fragments of a xanthene matrix with a substituted amino group at the 3 and 6 positions and an aromatic ring connected by a carbon atom at the 9 position. Rhodamine derivatives modified by introducing different functional groups into the structure can meet various detection needs. Compared with other commonly used fluorescent dyes, rhodamine-based fluorescent dyes have many advantages such as good light stability, insensitivity to pH, large extinction coefficient, longer absorption and emission wavelengths (generally >500 nm), and fluorescence quantum production. The rate is higher. Therefore, rhodamine compounds are extensively used in medicine, biology, environmental chemistry, information science and other fields, and are the most general used fluorescent dyes in biotechnology fields such as analytical chemistry and biomedical science.

Application of rhodamine dyes

Rhodamine dyes are a kind of very fundamental analytical reagents, which are extensively used in photometric analysis, fluorescence analysis and electrochemical analysis of inorganic components. In addition, rhodamine compounds with good molecular labeling and selection functions are also used for the detection of organic and bioactive molecules. As one of the most extensively used fluorescent probes in biology, rhodamine dyes are extensively used in the detection of small molecules in living cells, the analysis of biological macromolecules and the study of complex biological systems. Rhodamine dyes have been extensively used in gene analysis, DNA sequencing and microarray biological experiments. Rhodamine dyes can be used to label proteins, nucleic acids and other biomolecules. It should be noted that researchers should select appropriate fluorescent molecules when using rhodamine dyes to label proteins, in order to avoid protein aggregation, fluorescence quenching and other problems.
