and suspensions provide much be er contrast and definion,
producing sharper images with less background staining
ArroGen Ltd is the leading innovator in the field of fingerprint
development and finger mark analysis. Our advanced
technology based on SupraNano
par cles is revolu onising forensics and will boost the fight
against crime and terrorism. A range of stable core silica
nano-par cles has been engineered at the Supranano scale
to produce a targeted set of proper es suitable for a wide
range of powder products. The end par cle size is within the
normal powder range while employing standard opera onal
procedures and conforming to normal health and safety requirements.
Improving the Forensic Field
SupraNano Powders and Suspensions are applied using standard protocols
and have been demonstrated in
several studies to offer a superior li ed print resul ng in 20%- 40% be er
contrast and defini on across a range
of surfaces when compared to standard commercial powders: Specially formulated to develop latent marks on
non porous (e.g. glass, ceramics,) semi porous surfaces (e.g. plas cs, non ferrous metals,) and porous surfaces
up to twenty-eight days a er deposi on.
Features and Benefits
1. SupraNano Powders are both hydrophobic and hydrophilic meaning that they s ck much more closely to
finger mark surfaces and features with the poten al to provide much higher defini on and contrast than conven
onal powders.
2. SupraNano Suspension Sprays are especially suitable for li ing prints in wet condi ons and where water contamina on is present.
3. Applied in the normal way SupraNano magne c powders are designed not to clump and excess powder
is easily removed from the brush. Less propensity for staining compared to standard commercial powders.
4. Latent marks may be developed up to twenty-eight days a er deposi on.
5. Safe to use with no addi onal HSE requirements.
6. SupraNano Powders are available in both magne c and non-magne c forms in a wide range of
colours and fluorescents for use on different surfaces.
Independent Studies
Independent studies show a marked improvement in image and contrast across a range of surfaces
• Laminate Wood Surface – increase of 42% in defini on and 41% in contrast
• White Ceramic Tiles - increase of 27 % in defini on and 24 % in contrast
• Brown packing tape- increase of 34 % in defini on and 36 % in contrast
• Covering All Latent Fingerprin ng requirements

Applica on – Reported Comments
POWDERS
• The SupraNano powders li well and have much less propensity to smudge on acetate sheet
• In general SupraNano powders are finer and give a much smoother applica on.
• The SupraNano black magne c powder gives much less background staining.
• The SupraNano Black powder can be enhanced with a sweeping mo on while the excess is removed using
a clean brush.
• SupraNano magne c powders also work well with large flat magne c wands.
• SupraNano Fluorescent magne c powders with UV light are ideal for use on busy backgrounds e.g. paper
currency giving good contrast and defini on.
SUPRANANO SUSPENSION SPRAY
• The suspensions are at their best in outdoor scenes that have been we ed and dried or are s ll wet.
For example the outside of vehicles, UPVC windows/doors, glass, painted surfaces like fences and
even engineered/glazed bricks. Any semi smooth, no-porous/semi porous surface can be sampled.
• The Black suspension has been shown to work successfully on painted surfaces and Zinc coated security fences.
• The suspensions are designed to fluoresce at different wavelengths within the light spectrum while elimina ng
background interference under certain wavelengths. For example the Yellow Suspension is highly fluorescent
under UV long wave and blue light (300 – 450 nm) and is an excellent choice for many surfaces. The Green
Suspension is op mal under blue light (400 – 450 nm) and can be filtered using a band pass filter (yellow 470nm) for more specific searching.
Suspension Spray User Guide:
1. Shake the bo le to suspend the par cles. (Ensure that
the bo le nozzle is set to OFF in order to prevent spla er
when shaking)
2. Switch the nozzle bo le to SPRAY and aim the
suspension at the desired surface that you wish to
develop ridge detail on. On large surfaces start at the
bo om and work your way up sampling areas about
50cm x 50cm.
3. Gently spray the suspension evenly across the surface,
allow to run down the surface for a few moments and to
fully soak the area.
4. The spray can be concentrated on areas to build up
ridge detail as needed for weak marks.

5. Rinse the surface to remove excess suspension. This
can be done by either pouring or spraying water from
above that then flows down the surface removing excess
powder. This can be done using a standard garden pump
sprayer or jug. Ensure that the surface is completely clean
of un-adhered suspension. Do not spray water with force
directly at a visible mark as it may damage the developed
ridge detail.
6. If available to do so allow the visible mark to dry
before a emp ng to li . The mark can be li ed using
standard fingerprint li ing tape, hinge li er, Crystal
tab or Gel li er however, if me is of the essence then
photograph the mark in situa on before using a standard
gel li er to li the wet mark. This should be done very
gently and do not allow the Gel to slip as the mark will
be damaged. Once li ed onto the gel place into a gel
box and allow the gel to dry in a vehicle or lab. DO NOT
cover the gel with acetate whilst the mark is s ll wet.
7. Once all the visible marks have been
li ed the area that
has been examined can be cleaned down
using soap
and water.
8. The developed ridge detail can be visualised
using the
correct light source and band pass filter.

Fiber Duster Smooth
Fiber Duster Smooth now is guaranteed to offer you up to 40% lower print distoron
when processing for prints with regular powders.
Years ago, we were inspired by the research of some NASA polymer chemists and
engineers. Took us a while...and some money. But we finally came up with a patent-pending
treatment process that reduces the fric on coefficient of the actual
fiberglass filaments involved. Again, a minimum of 40-50% less print distor on.
Each durable, perfectly balanced Fiber Duster is carefully wound and trimmed by
us by hand…quality that you simply won’t get from other overseas or machine
made brushes. Smooth is quan ta vely be er. Heavy-handed techniques, possible
inexperience, one bad swipe or the fragility of the print you are working
on...all factors for choosing this brush.
Our brushes consistently work. They are affordable, durable and perfectly balanced.
They are also pre-broken-in and ready for any powder. They are even
washable.

ULTRA PURE CSI DFO
DFO (1,8-Diazafluoren-9-one) is a reagent that (like ninhydrin) reacts with the amino acids present in fingerprints.
The areas of applica on are the same: porous surfaces like paper, unpainted wood and the like.
A fingerprint developed with DFO is less visible in white light than a er treatment with ninhydrin but with
green light (about 530 nm), it fluoresces strongly. The fluorescence is viewed and photographed through
orange or red filter (goggles). Our DFO is prepared exclusively for Crime Sciences Inc. by the Casali Ins -
tute of Applied Chemistry. Purity makes the difference, and our DFO is of the highest purity (>99%), with
each batch analyzed by HPLC, with a cer ficate of analysis available. Don’t take a chance: eliminate one
more poten al variable in your formula on, by only using our highest purity material. We can supply any
size vial you require!

ULTRA PURE CSI 1,2-Indanedione
Indanediones can visulalize latent fingerprints as well as, or even be er than, DFO. Its ease of prepara
on, lower cost, and good solubility make it an excellent addi on to your fingerprint development
arsenal. Professor Yosef Almog, former head of the Israel Police division of iden fica on
and forensic science (DIFS) and now a researcher at the Casali Ins tute of Applied Chemistry, coordinated
the team that developed the reagent, including Professor Madeleine Joullié and her graduate
students, Dr. Diane Hauze and Dr. Olga Petrovskaia, from the University of
Pennsylvania (Upenn). During the evalua on of the compounds at the
U.S. Secret Service (USSS) by Dr. Tony Cantu and Robert Ramotowski, it
was discovered that these compounds were also capable of visualizing
latent prints. The powdered compound is very stable. However,
working solu ons should be made up whenever needed and should not be kept for extended periods. Like Ninhydrin,
latent prints visualized with Indanediones can be treated with zinc chloride to slow the fading of visible and luminescent
detail. In general, an increase in fluorescence is also observed a er treatment with zinc chloride. Prints developed
this way fluoresce at 530 nm like DFO, and can be viewed with a filter at 570 to 590 nm. Picture on le shows a
fingerprint cut in half, and treated with DFO on le side, and 1,2-IND on right side, under green light.
