(a) The picture of the free-hand measurement with the illustration of sample vapor. (b) The optical microscope image of MSS Chip I. Channels 1 to 4 are coated with poly(vinylidene fluoride), polysulfone, poly(4-methylstyrene) and polycaprolactone, respectively. (c) Sensing signals of MSS Chip I measuring ethyl acetate through the free-hand measurement; manually moving the chip at roughly 3 Hz.
