Future Prospects • MeV SIMS : in air analyses • Will allow larger molecular fragments to be imaged – i.e. chemical in<strong>for</strong>mation from fingerprints • Can we develop fingerprints on difficult surfaces – Patterned surfaces : e.g. money – Reagent development issues : covert analyses • Can we use SIMS/MeV SIMS to detect the sequencing of fingerprint /i ink
Conclusions • PIXE / PIGE / RBS / IBIL can be carried out simultaneously and are highly discriminating compared with other non-destructive techniques. • Work is in progress to establish the use of these techniques in police casework • SIMS / MeV SIMS are useful techniques <strong>for</strong> new types of fingerprint analysis
