Abstract
Processes for depositing functionalized nanoparticles upon a non-conductive substrate are disclosed herein. The processes may include the step of aerosolizing one or more particles into suspension within a gas, each of the one or more particles comprising functionalized nanoparticles having an electric charge. The processes may include the step the step of attracting the one or more particles onto a non-conductive substrate by a static electric charge opposite of the electric charge, wherein at least portions of the non-conductive substrate are having the static electric charge. The processes may include the step of depositing the functionalized nanoparticles onto the non-conductive substrate
Claims1
A sensor, comprising:
- a sensor element made by a process comprising the steps of:
- aerosolizing one or more particles into suspension within a gas, each of the one or more particles comprising functionalized nanoparticles having an electric charge;
- attracting the one or more particles onto a substrate by a static electric charge opposite of the electric charge, at least portions of the substrate having the static electric charge, the substrate being porous and non-conductive;
- and
- depositing the functionalized nanoparticles onto the substrate;
- and
- a detector in operable communication with the sensor element to measure a change in an electrical property of the sensor element.
