Embodiment 1
[0022] The sample is tested to determine whether it contains the virus - Bovine Viral Diarrhea Virus.
[0023] 1. KMnF 4 Nanoparticle preparation: KMnF 4 Nanoparticles can be purchased from the market, and can also be prepared by the following method: Weigh 1.6mmolMnCl 2 4H2O was added to the reaction kettle, then 10mL of absolute ethanol was added, and the solution was stirred until it was completely dissolved; 3 mmol of potassium oleate was weighed and added to the above solution, and stirred for 1-2min to mix well; 5-6g of fluoride Potassium (KF) is ground for more than 10 minutes. When the particle size becomes smaller and finer, weigh 4.98mmol and add it to the previous solution; add absolute ethanol again, usually 30mL; Put the kettle into the oven, adjust the temperature to 160°C, and react for 24 hours; when the reaction kettle drops to room temperature, it usually takes 3-4 hours after closing the oven. Open the reaction kettle, pour out the supernatant, wash with ...
