Abstract
Provided are a surface-modified nanoparticle that can be easily produced and can selectively deliver boron atoms into cancer cells and maintain the boron atoms, and a method for producing the surface-modified nanoparticle. The surface-modified nanoparticle of the present disclosure includes a nanocarbon material, and a surface-modifying group of the nanocarbon material, and has a group containing a boron atom as the surface-modifying group.
Claims15
A surface-modified nanoparticle comprising:
- a nanocarbon material;
- and
- a surface-modifying group of the nanocarbon material, wherein
- the surface-modified nanoparticle comprises a group containing a boron atom and a hydrophilic polymer chain as the surface-modifying group, wherein the hydrophilic polymer chain is a polyglycerol chain;
- the nanocarbon material comprises a nanodiamond particle, and
- a mass ratio of the nanodiamond particle [ND] to the surface-modifying group [ND/surface-modifying group] in the surface-modified nanoparticle is from 0.2 to 1.5.
