How do nanoparticles help fingerprinting?
The use of silica nanoparticles (SiO2-NPs) serves as a novel method of improving the detection of latent fingerprints because of their ease of synthesis and their ability to coat dyes, which prevents photo-decomposition 10.
What are the 3 different types of fingerprints investigators use?
The three fingerprint class types are arches, loops, and whorls. Arches are the least common type of fingerprint, occurring only about 5% of the time.
What is Nano forensics?
Nano-forensics is use of nanotechnology for the development of new tools for DNA isolation, fingerprint visualization, explosive detection, gunshot residue analysis, identification of body fluids, detection of illicit drugs, etc. in forensic science.
Which metal oxide is used to detect fingerprints?
The powders of metal oxides nanoparticles which include titanium dioxide, zinc oxide nanoparticles, iron oxide nanoparticles, europium oxide nanoparticles, silica nanoparticles have been used for latent fingerprint detection [10].
Who first used nanotechnology?
Norio Taniguchi
After fifteen years, Norio Taniguchi, a Japanese scientist was the first to use and define the term “nanotechnology” in 1974 as: “nanotechnology mainly consists of the processing of separation, consolidation, and deformation of materials by one atom or one molecule” [6].
What is the rarest fingerprint pattern?
Plain
1: The Arch. Plain Arch – Raised ridges characterize this pattern and they extend from one side of the finger to the other in a continuous fashion. This pattern makes up a mere 5% of the total population, making it the rarest type.
What is nanotechnology in criminal justice?
Nanotechnology is also helping differentiate forged products from originals. With the use of nanofibers and nanodots, police can prevent and detect counterfeiting crimes. Bio-Nanosensors are also finding application for detection of bioterror agents, drugs, explosives and identification of toxins.
Which country invented nanotechnology?

Is nanotechnology the future of forensic fingerprinting?
“Nanotechnology has proved to be a promising area of research for forensic fingerprint scientists and it is generally considered that nanotechnology may lead to the development of new materials and reagents with superior characteristics to conventional ones” says Maynard.
What is the best anti-fingerprint solution?
NBD Nano has invented a solution that makes fingerprints virtually invisible on glass, plastic and metal surfaces. This solution is unique because it uses an innovative approach for hiding fingerprints. It is a mechanism that is completely different from all other anti-fingerprint coatings.
What is anti-fingerprint coatings?
A thin yet durable protective layer. NBD Nano has created a solution that makes fingerprints virtually invisible on glass, plastic and metal surfaces. This solution uses an innovative approach for hiding fingerprints, completely different from all other anti-fingerprint coatings.
How to choose the right technique for fingerprint development?
Usually, the choice of the technique for fingerprint development is dependent on the composition of latent fingerprints, on the type of substrate and on the ability of the technique to be applied in sequence in the context of the case.
