NanoScent has developed and designed VOCID®, a platform for Volatile Organic Compound identification, patent-protected breakthrough technology is based on sensors capable of detecting volatile biomarkers at concentrations as low as 50 PPB. .
VOCID® can be tuned for multiple industrial applications by machine learning and hardware design.
Three Key System Components
The various parts of the platform work together to create three key system components, namely:
The pneumatic system sucks in the sample.
An electronic computing system with algorithms to provide predictions.
The core sensing element which is a sensor that NanoScent has developed for capturing molecules and their fingerprints
The VOCID® Sensor
The sensor is 1cm x 1cm and on it are 12 sensing elements and each one of them is really small and has a source and a drain. Distance between them is 10 microns. What we do at NanoScent is print this on a silicon chip and add in nanoparticles.
How do nanoparticles work?
So imagine on one side is the source and the other side the drain, in between the nanoparticles come in that are surrounded by organic compounds called ligands. These ligands are like little hairs. Now, when an organic compound comes in, these ligands move, either extracting or contracting and through this the electrical resistance pattern changes.
We take this pattern and we see if it exceeds the normal threshold, for example for COVID-19 diagnostics.
