Abstract: The present invention concerns a sensitive field effect device (100) comprising a semiconductor channel (110), a source electrode (120) connected to said semiconductor channel (110), a drain electrode (130) connected to said semiconductor channel (110), such that said semiconductor channel (110) is interposed between said source electrode (120) and said drain electrode (130), a gate electrode (140) and a dielectric layer (150) interposed between said gate electrode (140) and said semiconductor channel (110), characterized in that said semiconductor channel (110) is a layer and is made of an amorphous oxide and in that said sensor means (170, 171, 172, 173, 174, 175, 175) are configured to change the voltage between said gate electrode (140) and said source electrode (120) upon a sensing event capable of changing their electrical state. The present invention also concerns a sensor and a method for manufacturing said field effect device (100).

Abstract: The present invention relates to a system and process for detection and/or qualitative and quantitative identification of the biological material, such as specific sequences of nucleic acids or proteins as antibodies, present in biological samples. The system is composed by one or more light sources (1) combined with one or more integrated optical photo sensors, or not, and various electronic components (4), necessary for obtaining/processing of the signal emitted by the metal nanoprobes functionalized with a solution of biological composite, as well as also a micro-controller and a microprocessor, fixed or portable. This photosensor structure is able to detect and to quantify the color variations produced by metal nanoprobes, being this preferentially gold, functionalized by oligonucleotides complementary to specific DNA/RNA sequences, proteins, as for instance antibodies and/or antigens related with certain disease, or other sample or solution of biological composite, that are to be investigated.
