Embodiment 1
[0036] [Example 1] Adjusted raw materials of platinum tetrachloride 10% hydroxyapatite 90% antitumor agent
[0037] 1. Hydroxyapatite (HAP)
[0038] 2. Platinum tetrachloride (PtCl 4 )
[0039] 3. Sodium hydroxide: pH adjuster
[0040] 4. Citric acid: dispersant
[0041] 1 g of weighed platinum tetrachloride was added to previously distilled water, and after stirring, sodium hydroxide was added to adjust the pH to a neutral range (pH 6.8-7.4). Add 9g of weighed hydroxyapatite to this solution, stir under reduced pressure, add distilled water to this solution, adjust the total amount to 500ml, and carry out about 1 test in a sealed container at a constant temperature of 50-60°C in a dark place. month of stirring.
[0042] Stirring was stopped, concentrated with an evaporator, and freeze-dried to obtain a powder.
[0043]Distilled water was added to the powder to adjust the powder concentration to about 2%, and a dispersant was added to adjust the pH of citric acid to abou...
Embodiment 2
[0057] [Example 2] Adjusted raw materials of platinum hexachloride 10% hydroxyapatite 90% antitumor agent
[0058] 1. Hydroxyapatite (HAP)
[0059] 2. Platinum hexachloride (H 2 PtCl 6 )
[0060] 3. Sodium hydroxide: pH adjuster
[0061] 4. Sodium citrate: dispersant
[0062] 1.005 g of weighed platinum hexachloride was added to previously distilled water, and after stirring, sodium hydroxide was added to adjust the pH to a neutral range (pH6.8-7.4). Add 9 g of weighed hydroxyapatite to this solution, stir under reduced pressure, add distilled water to this solution, adjust the total amount to 200 ml, and stir in a sealed container in a dark place for about 2 months.
[0063] Stirring was stopped and freeze-drying was performed to obtain the powder of platinum hexachloride and hydroxyapatite.
[0064] Distilled water was added to the powder to adjust the powder concentration to about 1%, and sodium citrate was added as a dispersant to make the concentration 10 mM / l.

Embodiment 3
[0072] [Example 3] Raw material for adjustment of sodium hexachloroplatinate 10% hydroxyapatite 90% antitumor agent
[0073] 1. Hydroxyapatite (HAP)
[0074] 2. Sodium hexachloroplatinate (Na 2 PtCl 6 )
[0075] 3. Sodium hydroxide: pH adjuster
[0076] 4. Citric acid: dispersant
[0077] 1 g of weighed sodium hexachloroplatinate was added to previously distilled water, and after stirring, sodium hydroxide was added to adjust the pH to a neutral region (pH 6.8-7.4). Add 9g of weighed hydroxyapatite to the solution, stir under reduced pressure, add distilled water to the solution, adjust the total amount to 500ml, and carry out about 1 hour at a constant temperature of 50-60°C in a sealed container in the dark. months of stirring.
[0078] Stirring was stopped, concentrated with an evaporator, and freeze-dried to obtain a powder.
[0079] Distilled water was added to the powder to adjust the powder concentration to about 2%, and a dispersant was added to adjust the pH of...
