The human microbiome has been used to create microbial profiles, which is an intriguing field of forensic science research that can be used to identify a person. According to recent research, each person has a highly customized microbial fingerprint that can be used in forensics to recognize or connect a person with any criminal activity. Since this technique is still in its early stages, using a source tracker to locate the sink (microbial population) can be useful. On the basis of phospholipid, DNA, or RNA, microbial fingerprinting methods are being used to isolate and classify an individual community of microbes.
