The quantification of nonanal in armpit sweat was initially undertaken using solid-phase micro-extraction-gas chromatography-mass spectrometry (SPME GC-MS) with an external calibration standard. Nonanal concentrations in a sample exceeding 104 L are predicted to be linked with COVID-19 positivity, characterized by a sensitivity of 87% and a specificity of 89%, compared against RT-PCR data. In order to implement this in a practical setting, ethyl cellulose encapsulating helicene dye,
