Abstract

This invention is a functionalized diamond crystal with high dispersibility in high ionic strength solution and/or with specific targeting ability, which comprise a diamond crystal and a fatty acid layer. The fatty acid layer works a surfactant and provides a specific targeting feature for the diamond crystal. The feature of the surfactant makes the diamond crystal being easily dispersed in biological surrounding (e.g., phosphate saline buffer) and the feature of specific targeting ability provides the diamond crystal with specific recognizing specific targets. This invention allows researchers to use diamond crystal as a marker for specific labelling.
