Nine major applications of nanodiamond powder in medical fields

In recent years, as scientists have studied the biological properties of nano-diamonds, they have found that nano-diamonds have good biocompatibility, low toxicity, and fluorescence but no photobleaching. These excellent biological properties, chemical inertness and the modifiability of its surface genes make nanodiamonds have attracted the attention of many scientists in the field of biomedicine, and breakthroughs have been made. 1. Medical knives Surgical knives used for tissue resection have high requirements on the hardness, wear resistance, stability and biocompatibility of materials. The diamond material can not only meet the relevant requirements, but also the knives prepared with it have little extrusion and tear damage to the surgical site during the operation, and the wound edges are neat and easy to heal. At present, diamond surgical knives are mainly used in ophthalmology, neurosurgery, orthopedics and stomatology, as well as biological tissue slicing. 2. Medical materials Human tissues and organs may be damaged or lost due to diseases, trauma or natural aging. In order to replace this part of the tissue, people study the use of other materials to make implants into the human body. Among them, the material of the implant is very important: in order to meet the physiological and...
