In the context of POC diagnostic, spatial information is often not required. The information can be read by a singlepixel detector or in combination with a one-dimensional scan. Si PIN photodiodes have peak sensitivity in the NIR between 960 nm and 1000 nm, which is in the wavelength range of the (6,5)-SWCNT emission (Figure ). The price of these photodiodes (< 1€) is considerably lower than for InGaAs due to the high demand in consumer and telecommunication optoelectronics. Surprisingly, until now, no one utilized these photodiodes for the detection of NIR fluorescence signals of SWCNTs. The simulation results, as well as the low costs, suggest that Si PIN photodiodes have the potential to be as sensitive as InGaAs detectors and could be integrated into POC devices for biosensing with (6,5)-SWCNTs.
