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