Next-generation explosives detection

Arbsense is a state-of-the-art explosives detection solution for military, law enforcement and transport security use.

The sensing technology is based on dendrimers, a new class of highly selective materials.

Arbsense is available as a prototype only.
A market-ready solution is currently under development.


Arbsense is a highly selective detection device for explosives containing nitro groups, such as TNT, DNT or Nitro-glycerine.

Features include:

Proprietary sensing technology

Uses light-emitting dendrimers, a new highly customisable sensing materials platform that can be tuned to respond to different triggers


Reliable detection and avoidance of false positives


Vapour-sensing suitable for mass screening and detailed threat examination


Simple, user friendly with clear "go / no go" response using vibration, audio and visual alarms


Highly portable and versatile: small, lightweight device with Android-based app

The Arbsense App

Arbsense is operated by a custom Android application.

Communication between Arbsense and the Android device is via Bluetooth / wireless connectivity.

The app displays the response signal received from Arbsense.

It also provides additional warnings to the user including audio, visual signals and vibration.

The received signal is recorded by the app for later reference.

The app is capable of simultaneously managing and monitoring up to seven Arbsense sensing devices

Sensing Materials

Arbsense is based on functional dendrimers.

Functional dendrimers are a new class of organic semi-conductor sensing materials. Dendrimers are macro-molecules that consist of a core which is surrounded by branched ('dendritic') structures.

Functional dendrimers are highly flexible and can be used for a variety of opto-electronic applications, such as light emitting diodes, solar cells, chemical sensors and image sensors.

For the application of explosives sensing, Arbsense uses light-emitting (fluorescent) dendrimers. When excited by light, the core of the dendrimer re-emits light at a longer wavelength. When the dendrimer comes in contact with an explosive, the signal strength of the light decreases. This decrease is measured by Arbsense and is used to alert the user about detected explosives.

About Us

Arborescent was founded in 2003 by the management and research team behind Opsys.

Opsys commercialised functional dendrimers for use in organic light-emitting diodes and was later sold to CDT.

Arborescent's objective is to commercialise the many additional applications from functional dendrimers, including sensors for explosives detection, image sensors and solar cells.

Arborescent works in close partnership with researchers led by Professor Paul Burn of the Centre for Organic Photonics and Electronics at the University of Queensland, Australia.
