Materials used in biomedicine must be characterized by controlled biodegradability, sufficient strength and total absence of toxicity to the human body. The search for such materials is, therefore, not a simple task. In this context, scientists have been interested in magnesium for a long time. Recently, using such techniques as positron annihilation spectroscopy, the researchers were able to demonstrate that magnesium subjected to surface mechanical attrition treatment obtains the properties necessary for a biocompatible material.
