Abstract

The invention provides a preparation method of copper sulfide nano rose. The preparation method comprises the following steps: cleaning treatment of a copper bar: the copper bar is washed with acetone, ethanol, 2 mol / L dilute hydrochloric acid and distilled water under an ultrasonic condition; (2) preparing of copper sulfide nano rose: monovalent silver salt and sulfur source are dissolved in the distilled water respectively and then stirred up; the cleaned copper bar is placed into a 5 mL test tube, a monovalent silver salt solution is dropped into the test tube by a dropper, then a sulfur source solution is dropped into the test tube, the test tube is shaken to enable the two solutions to be uniformly mixed and then sealed, the mixture is allowed to react for 10 min-12 h at normal temperature; after the reaction is ended, and the copper rod with black substance is washed with distilled water and allowed to naturally dry in the air. The preparation method disclosed by the invention is high in reproducibility, simple and convenient to operate, low in synthesis cost and suitable for industrial preparation; and the prepared nanometer rose is large in specific surface area and can be in full contact with an to-be-detected object as a sensor material.

Description

Technical field [0001] The invention relates to a preparation method of cuprous sulfide nano rose. Background technique [0002] Cholesterol has a wide range of physiological functions in the body, and its concentration is a key indicator in many diseases, such as arteriosclerosis, venous thrombosis and gallstones. Therefore, it is very meaningful to find a method to quickly and accurately determine cholesterol, and we have been working hard to develop a reliable cholesterol biosensor. Due to its simple operation, high selectivity and low cost, it can measure current The cholesterol biosensor has received widespread attention. Among them, the focus is on biological enzyme sensors, which have high sensitivity and good selectivity, but the enzyme activity will decrease during use. Due to its inherent instability and enzyme activity, it is susceptible to pH, temperature, and toxic chemicals. In the process of fixation, the enzyme is easy to denature. In addition, the reproducibil...
