We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector.

We have successfully performed some experimental evaluations of the detection principle and are in the stage of optimization of several parts of the system. As shown in the figure of the experimental system there are three parts of the system that need to be optimized: the nucleation-condensation part, the sensor part and the electronics. Here we will present some numerical modeling results of sensor operation and expose some further possible improvements and collaborations.
