Because expenditure on research and development of forensic science is pitifully small, forensic scientists will have to adapt developments occurring in other fields. In analytical chemistry, the underlying trend lies in improving resolution and sensitivity of techniques. In forensic science, this means that chromatography will be applicable to a wider range of fluids and can deal with smaller and smaller quantities. Improvements in spectrometers based on digital techniques and the use of Fourier transforms will increase sensitivity, also critical in forensic examinations. The successful coupling of liquid chromatography with mass spectrometry should improve forensic analysis of drugs and metabolics in body fluids. Other advances in spectroscopic techniques will find considerable application in the examination of small specimens. Molecular biology research into DNA someday may allow individuals to be identified reliably by chemical analysis instead of blood tests or fingerprints. The miniaturization of electronics opens the possibility of taking the laboratory to the crime scene instead of vice versa. Computerized information systems can increase laboratory efficiency to meet increasing demands with limited manpower sources. In order to tap these resources, forensic scientists must call attention to the effectiveness of existing services and how they have benefited from recent expenditures. In addition, the private sector must be encouraged to spend more money on such crime prevention and detection research.
