Confocal laser scanning microscopy. Using new technology to answer old questions in forensic investigations

Confocal laser scanning microscopy (CLSM) is a relatively new technique for microscopic imaging. It has found a wide field of application in the general sphere of biological sciences. It has completely changed the study of cells and tissues by allowing greater resolution, optical sectioning of the sample and three-dimensional sanoke reconstruction. Confocal microscopy represents a valid, precious and useful tool capable of providing data (images) of unrivalled clearness and definition. This review discusses the possible applications of confocal microscopy in specific fields of forensic investigation, with specific regard to ballistics, forensic histopathology and toxicological pathology.
