摘要：
The present invention relates to a resorbable implant material made of magnesium or magnesium alloy and to a process for the production thereof. A disadvantage of the known resorbable implants is that their resorption has hitherto only been trackable using x-ray or CT examinations. The invention provides a resorbable implant material comprising homogeneously distributed fluorescent nanodiamonds in a matrix of magnesium or a magnesium alloy. Fluorescent nanodiamonds are biologically nonhazardous and provide a stable emission in the near infrared range due to nitrogen-vacancy centers (NV centres). This allows detection of the implant material in the blood plasma of the patient.The resorbable implant material according to the invention is produced by a process wherein magnesium or a magnesium alloy is melted, nanodiamonds are added to the melt and the melt of magnesium or a magnesium alloy provided with nanodiamonds is subjected to an ultrasound treatment.
