The concept of immune-chromatography is a combination of chromatography (separation of components of a sample based on differences in their movement through a sorbent) and immunochemical reactions. When the liquid sample is dropped on the sample pad, the antigen in the sample forms an immunocomplex (Ag-Ab complex) with the antibody labelled with colloidal gold. As a result, digital forensic scientists have had to develop methods for collecting, analyzing, and evaluating data collected from the cloud. It is based on the same principle as that of ELISA sandwich technique, differing on that the immunological reaction is carried out on the chromatographic paper by capillary action. Here are six major forensic breakthroughs related to technology that are changing the way crimes are processed.
