Abstract
A method of fabricating a multi-functional platform including at least one gas sensor. The method comprises the steps of providing a printed circuit board (PCB) including a chip integrated on the PCB, and providing a picoliter dispenser having a moveable dispenser head with a nozzle. Then, a gas sensor base layer is formed by depositing a nanostructure directly on a substrate of the chip. The nanostructure includes an unfunctionalized nanomaterial. Next, the gas sensor base layer is functionalized by deposing a functional group of nanomaterial to the gas sensor base layer using the picoliter dispenser so as to form the at least one gas sensor. Alternatively, the gas sensor is fabricated by preparing a suspension of unfunctionalized nanomaterials, then functionalizing the suspension of the unfunctionalized nanomaterials by mixing the unfunctionalized suspension with one of different functional groups, then depositing the functionalized suspension directly to the chip using the picoliter dispenser.
