Embodiment 1
[0063] A kind of manufacture method of nano selenium, it is characterized in that the method has the following steps:
[0064] In 800 milliliters of solutions containing 8 volume percent plasma protein and 0.5 volume percent hemoglobin, add 2.0 grams of sodium selenite, keep warm in a water bath at 50-60 ° C, and accurately add 1.0 milliliters of hydrazine hydrate (H 4 N 2 ·H 2 O), to complete reaction, the reaction time is 4 hours. At this time, the solution is red, and the particle size is 100 nm or about 100 nm under an atomic force microscope. (see picture 1).
Embodiment 2
[0066] A kind of manufacture method of nano selenium, it is characterized in that the method has the following steps:
[0067] In 1200 milliliters of solutions containing 12 volume percent plasma protein and 1.5 volume percent hemoglobin, add 2.4 grams of sodium selenite, keep warm in a water bath at 50-60° C., and accurately add 2.0 milliliters of hydrazine hydrate until the reaction is complete.
[0068] At this time, the solution is red, and the particle size is 100 nm or about 100 nm under an atomic force microscope. (see picture 1).
Embodiment 3
[0070] A kind of manufacture method of nano selenium, it is characterized in that:
[0071] In 1000 ml of solution containing 10 volume % plasma protein and 1.0 volume % hemoglobin, add 2.2 g of sodium selenite to make 1 g of selenium in it, keep it warm in a water bath at 56°C, add 1.5 ml of hydrazine hydrate accurately, and pass spectroscopic The photometer measures the absorbance of 546nm wavelength to detect the completeness of the reaction, and the reaction is carried out until the absorbance is stable and no longer increases, and the reaction time is 4-6 hours.
[0072] At this time, the solution is red, and the particle size is 100 nm or about 100 nm under an atomic force microscope. (see picture 1).
