A first prototype of an electro-optical nose has been designed, assembled and tested. This new system is made up of a matrix of silicon integrated photodiodes (the electro-optical transducers), coated by different thin films of metalloporphyrins (used as chemically interactive material -CIM- with a function of incident light filter), and of a blue LED source with an emission peak centred in the main absorption band of the CIM (the Soret Band, around 430 nm).

Abstract
A first prototype of an electro-optical nose has been designed, assembled and tested. This new system is made up of a matrix of silicon integrated photodiodes (the electro-optical transducers), coated by different thin films of metalloporphyrins (used as chemically interactive material -CIM- with a function of incident light filter), and of a blue LED source with an emission peak centred in the main absorption band of the CIM (the Soret Band, around 430 nm).File in questo prodotto:
