Method for Producing Fluorescent Nanodiamonds |
| abstract |
The present invention, a first step of preparing nanodiamonds having an average particle diameter of 10 nm or less; a second step of implanting plasma ions into the nanodiamond; a third step of heat-treating the nanodiamonds implanted with plasma ions under a vacuum or inert gas atmosphere; a fourth step of oxygenating the surface of the nanodiamonds by heat-treating the heat-treated nanodiamonds in a gas atmosphere containing oxygen; a fifth step of acid-treating the oxygenated nanodiamonds; a sixth step of centrifuging and washing the acid-treated nano-diamonds; and a seventh step of drying the washed nanodiamonds, wherein the second step is to implant plasma ions with an incident ion density of 10 13 ions/cm 2 or more and 10 20 ions/cm 2 or less. It relates to a method for manufacturing nanodiamonds. Fluorescent nanodiamonds according to an exemplary embodiment of the present invention have no cytotoxicity, so they can be freely used in biological fields such as bio-imaging and drug delivery. Since explosive nanodiamonds having a size of 10 nm or less are used as a basic material, a complicated grinding process is required. No, it is possible to increase productivity by applying a plasma ion implantation process that effectively forms pores in a large-area sample. |
