Abstract

With the rapid advancement of biological technologies, their application in forensic science has become increasingly widespread, serving as a crucial pillar for case investigation and judicial identification. This paper systematically reviews the progress in the application of DNA technology, proteomics, and microbiological techniques in forensic science. It compares the advantages and limitations of various technologies and explores the prospects for their integrated application. The study indicates that DNA extraction and analysis techniques, protein mass spectrometry imaging, and microbiome analysis hold significant value in individual identification, time-of-death estimation, bodily fluid identification, and drowning diagnosis. Research indicates that methods such as DNA extraction and analysis, protein mass spectrometry imaging, and microbiome analysis hold significant value in individual identification, time-of-death estimation, bodily fluid identification, and drowning diagnosis. Looking ahead, the integration of automation, artificial intelligence, and multi-omics technologies will propel forensic biology towards greater efficiency, precision, and intelligence, providing stronger scientific foundations for judicial practice.
