The principle hours of a crime scene investigation are usually of critical prominence for the police/forensic analysts to get more information and insights about the identity of potential suspects; and to obtain relevant facts and data. The development of portable methods that allow forensic analysis at scene of crime with good sensitivity and precision is extremely desirable. In this sense, the detection of toxic substances is of great importance to strategic and humanitarian demining, forensic criminal investigation, as well as remediation of the victim at the crime scene. In cases of poisoning a simple change in colour or intensity may indicate alertness for critical decision.Pesticides are major poisonous substances encountered in suicide as well as in accidental cases. Profenos and Cypermethrin are two such OP pesticides reported in several poisoning cases. In the present study, to detect these pesticides, Nimbdin (Azadirecta indica), is used as sensing media. When sample is diluted and added into this extract, its fluorescence intensity decay.The decay of fluorescence is measured by fluorescence spectrophotometry, fluorometric graph shows the decay of fluorescence is decreased when volume of sample is added in it.
