Forensic nanotechnology uses nano-sensors, microfluidic devices, and nanoparticles to aid in criminal investigations. Nano-sensors allow for toxicological analysis with low cost and effectiveness. Microfluidic devices improve DNA analysis through shorter examination times and minimal contamination. Gold nanoparticles target amino acids to better analyze latent fingerprints, while magnetic nanoparticles extract high quality PCR samples. Nanomaterials also help detect explosive residues from bomb blasts and create sensors to identify conventional bombs and grenades. Instruments like SEM imaging and X-ray spectrometry analyze gunshot residue particles.

5. APPLICATIONS OF FORENSIC
NANOTECHNOLOGY

6. Forensic nanotechnology is applied to real
specimens in order to illuminate the
applicability of the Nano-sensors for
toxicological analysis.
They are low of cost, active and effective.

7. Microfluidic devices are the recent
advanced devices used in forensic DNA
analysis.
They take shorter examination time, risk
of contamination is minimal, and it is
directly applicable at the scene of crime.

8. Nano-powders have been developed
and used with SALDI-TOF2-MS to
develop the finger-prints.
Gold nanoparticles are used to target
amino acids on non-porous surfaces,
allowing in better analysis of latent
fingerprints.

9. Silica based magnetic nanoparticles and copper
nanoparticles are used in order to extract
excellent quality of PCR.
The magnetite nanoparticles with carboxylic
compounds are used as adsorbents for PCR
amplification

10. Here, Nanotechnology is useful in post
blast explosive residue analysis,
as when the fragmentation of explosives
occur in bomb blast incidents
and traces of explosive residues remain
at the spot,

11. Nano materials provide an active
potential to create sensors for detection
of explosives.
Advanced Nano-sensor devices like
electronic noses, nanotube and
nanomechanical devices are used to
detect the conventional bombs, plastic
explosives and grenades.

12. Instruments like High-resolution
SEM imaging is used to locate
gunshot residue particles, and X-
ray spectrometry is used to
determine the composition of the
elements.
