Schematic diagram of the DNA-derived electronic nose. a A sequence of 20 amino acids associated with DNA serving as a blueprint for mammalian olfactory receptor cells. Each selected DNA sequence was implanted into a M13 bacteriophage using genetic engineering methods. b Sequence listing of genetically engineered M13 bacteriophage. c Arrangement of the phage film. d Mean colour distance measured by respiration of 31 healthy subjects (left) and 31 patients (right). e classification success scores (CSS) histograms calculated for all possible combinations of 20 films. f HCA dendrograms based on the best multi-array colourimetric sensor combination selected via neural pattern separation (NPS). Labels i, ii, and iii represent patients with tumours all in the upper lobe and peripheral lesions
