Nanotechnology, as enabler of the miniaturization of devices in a scale ranging from 1 to few hundreds of nm , represents a viable solution for " alternative" communication paradigms that could be effective in complex networked systems, as body area networks. Traditional communication paradigms are not effective in the context of joint body and nano-networked systems, for several reasons, and then novel approaches have been investigated such as nanomechanical, electromagnetic, acoustic, molecular, etc. On the other hand, quantum phenomena represent a natural direction for developing nanotechnology, since it has to be considered as a new scale where new phenomena can occur and can be exploited for information purpose. Specific quantum particles are phonons, the quanta of mechanical vibrations (i.e., acoustic excitations), that can be analyzed as potential information carriers in a body networked context. In this paper we will focus on the generation of phonons from photon-phonon interaction, by irradiating a sample of human tissue with an electro-magnetic field, and then we will theoretically derive the information capacity and the bit rate in the frequency range [10 - 10] Hz.

“…For instance, in nanomedicine, the use of nanodevices (i.e. nanorobots and nanosensors, opportunely functionalized with medicament) are intended to both diagnostic and therapeutic purposes [1]- [3] by enhancing their effectiveness, as well as increasing their tolerability in the body by interfering at a minimum level with the immune system [4]. Novel nanomedicine applications arise to the term "theragnostics", which is intended as a treatment Valeria strategy combining therapeutics with diagnostics.…”

Innovative diagnostic approaches and therapies are more and more based on the use of injections or oral delivery of nanoparticle sized substances. For a better understanding of the overall phenomena, aiming to facilitate a safe application at large scale, the development of accurate models and analysis techniques are required. These techniques take into consideration different aspects of the overall process: accurate numerical modeling of the different phases of the nanoparticles in the body, and knowledge of the local environment, that can be varying very fast within a short-range in the body itself. Such aspects should be taken into account to correctly predict the amount of drug and its timely release for the specific disease. Deep and accurate analysis of the interaction between the nanoparticles and the biological fluid where the nanoparticles are immersed is mandatory for an efficient correlation of all these aspects. Because of their biocompatibility, in this paper, we focus our attention on systems of Titanium (Ti), and its oxide (e.g., TiO2), given their specific features in terms of density, lack of cytotoxic effects, etc. Specifically, we present the study and design of an in-body system by characterizing each of the emission, diffusion, and reception processes with a proper realistic model. The theoretical investigation is further supported by experimental study of the morphology and other important characteristics (e.g., the pH of the particles, and thermal stability) of TiO2 systems when immersed in a Ringer solution, in order to derive important information related to their potential toxicity inside the human body.

“…Specific features of human body need to be taken into account in order to derive a biological propagation model for nanocommunications. Di↵erent communication alternatives have been considered, such as molecular and nano-communications [1], acoustic [2], molecular communications based on Forster Resonance Energy Transfer (FRET) phenomenon [3] just to mention some of them. A step towards the miniaturization at nanoscale level can be also moved by considering quantum phenomena.…”

Quantum phenomena represent a natural direction for developing nanotechnology, since it has to be considered as a new scale where new phenomena can occur and can be exploited for information purpose. Specific quantum particles are phonons, the quanta of mechanical vibrations (i.e., acoustic excitations), that can be analyzed as potential information carriers in a body network context.In this paper we derive the theoretical expression of the channel capacity of a phonon-based quantum network. By irradiating a sample of biological human tissue with an electromagnetic field, we obtain the generation of phonons from photon-phonon interaction, and can observe the information capacity in the frequency range [1012 ] Hz.
