The used technique allowed the investigation of the effects coming out from the interaction between P. polycephalum and polyaniline. Thus, the contactless method of the analysis of polyaniline conductivity state resulted from the slime mold metabolism was suggested. Indeed, it is here demonstrated that P. polycephalum can modify properties of polyaniline due to its internal activity in contact zones.

In this interesting branch the self-assembly approach is highly exploited; it consists in spontaneous formation of highly ordered monolayers on various substrate surfaces. Self-assembled monolayers (SAMs) have found their applications in various areas, such as nanoelectronics, surface engineering, biosensing, etc. An important area in biosensing is the electrochemical detection, that enables sensing of dierent biomarkers with an important role, for many dierent applications in biomedical diagnostics or in monitoring of biological systems. Various test structures have been developed in order to carry out characterizations of self-assembled molecules, and numerous reports have been published in the past several years on the transport characteristics. This thesis' purpose is the single protein biomolecular sensing, that could become the starting point for monitoring drugs, developing cle...

Whereas demonstrations of simple neural networks (e.g., a single-layer perceptron) based on memristors already exist, the implementation of more complicated networks is more challenging and has yet to be reported. In this study, we demonstrate linearly nonseparable combinational logic classification (XOR logic task) using a network implemented with CMOS-based neurons and organic memrisitive devices that constitutes the first step toward the realization of a double layer perceptron. We also show numerically the ability of such network to solve a principally analogue task which cannot be realized by digital devices. The obtained results prove the possibility to create a multilayer ANN based on memristive devices that paves the way for designing a more complex network such as the double layer perceptron.

The concept of memory is particularly well suited for mimicking learning behavior in biosystems and in information processing systems being capable of coupling inherently memory and logic capabilities. Bio-electronics is another challenging platform, mostly if we consider organic devices based on conductive and biocompatible polymers. This chapter deals with several examples of devices developed by joining unconventional computing, organic memristors and living being. Starting from organic memristors we realized logic gates with memory and a single layer perceptron. We developed hybrid systems based on living beings as key elements for the proper device working, in particular with Phyarum polycephalum and neurons. These devices enable new and unexplored opportunities in such emerging field of research.

In particular, organic-based memristors allow the construction of circuits capable of learning. Physarum Polycephalum slime mold is well suited for the implementation of the functional properties of smart living systems into electronic devices. Physarum has memory patterns that can be associated to learning, generally considered a feature of more complex species. Here we presents the characteristics of an hybrid memristor developed by interfacing poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate), (PEDOT:PSS), with Physarum Polycephalum (PP). The device has memristive features resulting by electrochemical changes occurring into the polymer upon application of anodic potentials across the semiconducting PEDOT:PSS channel.
