Claim:
1. A thiolation method for modifying nanodiamonds comprising: providing nanodiamonds synthesized by a detonation method; providing a carboxylation step, wherein the nanodiamonds are reacted with an oxidant for generating carboxyl groups on surfaces of the nanodiamonds so as to form carboxylated nanodiamonds; providing a hydroxylation step, wherein a reductant is added for transforming the carboxyl groups of the carboxylated nanodiamonds into hydroxyl groups so as to transform the carboxylated nanodiamonds into hydroxylated nanodiamonds, and the reductant is lithium aluminium hydride (LiAlH providing a thiolation step, comprising:
