TI  - Expanding the Efficacy of Fingermark Enhancement Using ToF-SIMS.
LID - 10.3390/molecules28155687 [doi]
LID - 5687
AB  - Time-of-flight secondary ion mass spectrometry (ToF-SIMS) has been shown to 
      enhance fingermark recovery compared to standard processes used by police forces, 
      but there is no data to show how generally applicable the improvement is. 
      Additionally, ToF-SIMS can be run in either positive or negative ion mode (or 
      both), and there is no data on which mode of operation is most effective at 
      revealing fingerprints. This study aims to fill these gaps by using ToF-SIMS to 
      image fingerprints deposited on two common exhibit-type surfaces (polyethylene 
      and stainless steel) using 10 donors and ageing fingerprints in either ambient, 
      rainwater, or underground for 1 and 5 months. In all, 120 fingerprints were 
      imaged using ToF-SIMS, and each was run in positive and negative modes. A 
      fingerprint expert compared the fingerprint ridge detail produced by the standard 
      process to the ToF-SIMS images. In over 50% of the samples, ToF-SIMS was shown to 
      improve fingerprint ridge detail visualised by the respective standard process 
      for all surfaces tested. In over 90% of the samples, the ridge detail produced by 
      ToF-SIMS was equivalent to standard development across all different ageing and 
      exposure conditions. The data shows that there is a benefit to running the 
      ToF-SIMS in both positive and negative modes, even if no ridge detail was seen in 
      one mode.
