In recent years many studies have highlighted the great potential of microbial analysis in human identification for forensic purposes, with important differences in microbial community composition and function across different people and locations, showing a certain degree of uncertainty.
The possibility of using the human microbiome as a means of personal identification undoubtedly represents a fascinating and innovative field of research. The establishment of dedicated biobanks for the development of research in this area would allow for the obtaining of reproducible and robust results to allow these techniques to be used in the very near future, even in real criminal cases. Applying new technologies or considering new applications of technologies that have already been consolidated in the forensic and judicial field means proceeding on two tracks: on the one hand, research, to update knowledge; and on the other, to keep in consideration the regulatory and ethical aspects.
