Technology

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.

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.
