Nanoplasmonic imaging of latent fingerprints and identification of cocaine.
Search for traces: Aptamer-bound Au nanoparticles (Au NPs) were used to provide high-resolution dark-field microscopy images of latent fingerprints (LFPs) with level 2 and level 3 details. Furthermore, the cocaine-induced aggregation of Au NPs results in a true green-to-red color change of the scattered light, providing a quasi-quantative method to identify cocaine loadings in LFPs.
متن کاملA Study of Latent Fingerprint Matching Approaches
Fingerprint based identification is one of the most mature and proven technique compare to the all biometric technique. In crime sense fingerprints have been extensively used for identification of criminals. Fingerprints are classified as rolled, plain and latent fingerprints. Latent fingerprints are lifted from surface of objects that are unintentionally touched by person. Latent means poor qu...
متن کاملIdentification of recently handled materials by analysis of latent human fingerprints using infrared spectromicroscopy.
Analysis of fingerprints has predominantly focused on matching the pattern of ridges to a specific person as a form of identification. The present work focuses on identifying extrinsic materials that are left within a person's fingerprint after recent handling of such materials. Specifically, we employed infrared spectromicroscopy to locate and positively identify microscopic particles from a m...
متن کاملForensic applications of chemical imaging: latent fingerprint detection using visible absorption and luminescence.
Chemical imaging technology is a rapid examination technique that combines molecular spectroscopy and digital imaging, providing information on morphology, composition, structure, and concentration of a material. Among many other applications, chemical imaging offers an array of novel analytical testing methods, which limits sample preparation and provides high-quality imaging data essential in...
متن کاملDevelopment of latent fingerprints on non-porous surfaces recovered from fresh and sea water
BACKGROUND Criminal offenders have a fundamental goal not to leave any traces at the crime scene. Some may suppose that items recovered underwater will have no forensic value, therefore, they try to destroy the traces by throwing items in water. These traces are subjected to the destructive environmental effects. This can represent a challenge for forensic experts investigating fingerprints. ...
