Studying the Activity of Organic and Inorganic Materials for Identifying Fingerprints on Different Surfaces

Abstract

Organic and inorganic chemical compounds were chosen to play as developer for pattern fingerprint and convert to visible fingerprint. The process was used two chemical compound sodium carbonate Na₂CO₃ as inorganic material and succinic acid C₇H₆O₂ as organic material. The methodology was powder method three surface for compare which was iron, aluminum and wood surface. the infra red spectrum and optic microscopy were used to identified the nature of interaction between the surface under tasting and the powder of organic and inorganic material. The results were shown abilities for organic materials (succinc acid) to make patterns fingerprint for visible fingerprint in two types of surfaces iron and aluminium which failed to make that on wood surface.
