Characterization of molecular communications among implantable biomedical neuro-inspired nanodevices
Publication date: June 2013 Source:Nano Communication Networks, Volume 4, Issue 2 Author(s): Laura Galluccio , Sergio Palazzo , G. Enrico Santagati In the next future nanodevices are expected to be implanted in the human body and communicate with each other as well as with biological entities, e.g. neuronal cells, thus opening new frontiers for disease treatment, especially in neurological therapy and for drug delivery. Moreover, considering that these nanoscale devices will be small in size, will have limitations in terms of energy consumption and processing and will be injected into a biological system, they will ...

Nano-machine molecular communication over a moving propagation medium
Publication date: September 2013 Source:Nano Communication Networks, Volume 4, Issue 3 Author(s): Hoda ShahMohammadian , Geoffrey G. Messier , Sebastian Magierowski In this paper, we study a molecular communication system operating over a moving propagation medium. Using the convection–diffusion equation, we present the first separate models for the channel response and the corrupting noise. The flow-based molecular channel is shown to be linear but time-varying and the noise corrupting the signal is additive white Gaussian with a signal dependent magnitude. By modelling the ligand–receptor binding process, it i...

Communication theoretic analysis of the synaptic channel for cortical neurons
Publication date: September 2013 Source:Nano Communication Networks, Volume 4, Issue 3 Author(s): Derya Malak , Murat Kocaoglu , Ozgur B. Akan In this paper, we develop a realistic model of the synaptic multiple-input single-output (MISO) communication channel for cortical neurons. The synaptic channel weights change adaptively according to the rules of spike timing-dependent plasticity (STDP) to enable learning and memory within neuronal connections. We calculate the ergodic capacity of the synaptic multiple-input multiple-output (MIMO) communication channel, and investigate its performance using the statistical pr...

Optimal coding for transmission energy minimization in wireless nanosensor networks
Publication date: September 2013 Source:Nano Communication Networks, Volume 4, Issue 3 Author(s): Kaikai Chi , Yi-hua Zhu , Xiaohong Jiang , Xianzhong Tian Wireless nanosensor networks (WNSNs), which consist of nanosensors with the size of just a few hundred nanometers, can sense new types of events at nanoscale and thus are promising for lots of important applications, like intrabody drug delivery, air pollution surveillance, etc. Since nanosensors are highly energy-constrained, it is critical to adopt energy-efficient protocols for communications in WNSNs. This paper focuses on WNSNs adopting the on–off keying ...

Noise properties of linear molecular communication networks
Publication date: September 2013 Source:Nano Communication Networks, Volume 4, Issue 3 Author(s): Chun Tung Chou Molecular communication networks consist of transmitters and receivers distributed in a fluid medium. The communication in these networks is realised by the transmitters emitting signalling molecules, which are diffused in the medium to reach the receivers. This paper investigates the properties of noise, or the variance of the receiver output, in molecular communication networks. The noise in these networks come from multiple sources: stochastic emission of signalling molecules by the transmitters, diffusi...

On Delaunay triangulation automata with memory
This study focuses on the analysis of the dynamics of parity automata on Delaunay triangulations (DTs): a kind of relatively highly connected proximity graphs endowed with a very active rule. The inertial effect of memory of past states is fully considered in this context, whereas other related contexts, such as cellular DT automata, are briefly tackled.

Introducing purely hydrodynamic networking functionalities into microfluidic systems
Publication date: December 2013 Source:Nano Communication Networks, Volume 4, Issue 4 Author(s): Andrea Biral , Andrea Zanella Microfluidics is a multidisciplinary field with practical applications to the design of systems, called lab-on-chip (LoC), where tiny volumes of fluids are circulated through channels with millimeter size and driven into structures where precise chemical/physical processes take place. One subcategory of microfluidics is droplet-based microfluidics, in which discrete volumes of fluids disperse into a continuous stream of another immiscible fluid, which acts as the droplet carrier. Droplets can...

Artificial nanotube connections and transport of molecular cargo between mammalian cells
We present a set of microfabrication procedures for the deliberate formation of intercellular nanotube links between single mammalian cells, employing microneedle manipulation protocols, developed earlier for nanotube-vesicle networks. Cell-to-cell connections were established, and their effectiveness for intercellular transport of molecular cargo was demonstrated. We initiate transport of Ca 2 + ions and fluorescein diphosphate, a prefluorescent enzyme substrate, between cells, and demonstrate the validity and effectiveness of artificially created nanotube connections for cell-to-cell communication. We thus prov...
