Our miniaturized sensor for nanoparticles is based on the detection of the time-dependent capacitance. The measured change of the capacitance is caused by the impact of a nanoparticle covered with condensed water, to the water situated in the sensor. The impact of the nanoparticle, causes a crater in the water, which causes the change in the capacitance. A proof-of-concept was already demonstrated, patented (US 9,151,724 B2), and published in peer reviewed journals.

Our sensor can be used for: (1) Air Quality: Measuring the distribution and size of aerosols in indoor air; (2) Medical: Testing of inhaler-dosed drugs; (3) Meteorology: Analysis of droplet size in the atmosphere.
