Abstract

The invention provides a polythymine template, a fluorescent copper nano-cluster based on the same, a preparation method of the fluorescent copper nano-cluster and an ATP detection method. The polythymine template has a single-chain DNA sequence and comprises at least one polythymine sequence which is (T)n, wherein n refers to natural number ranging from 15 to 40. The polythymine template can be used for preparing the fluorescent copper nano-cluster, preparation cost is low, and operation is simple and convenient. The ATP detection method is low in cost, simple and easy-to-implement in detection step, obvious in phenomenon, easy for observation and capable of quickly detection concentration of ATP in a sample in a high-sensitivity manner.

Description

technical field [0001] The invention relates to the field of nanomaterials and molecular detection, in particular to a polythymine template, a fluorescent copper nanocluster based on the polythymine template and a preparation method thereof, and an ATP detection method. Background technique [0002] ATP has an important influence on the activity of many enzymes, and its increase or decrease will cause various diseases, such as hypoxia, hypoglycemia, Parkinson's disease and malignant tumors. Therefore, simple and rapid detection of ATP is crucial for the treatment of related diseases. The current method for detecting ATP mainly uses luciferin and luciferase detection. Although its detection accuracy is high, the cost is high and the steps are relatively complicated, so it is not suitable for rapid detection. [0003] Therefore, it is necessary to provide a low-cost, easy-to-operate method that can detect ATP quickly and with high sensitivity. Contents of the invention ...
