Posted to arXiv: Biophysical Model for Signal-Embedded Droplet Soaking into 2D Cell Culture

Our paper "Biophysical Model for Signal-Embedded Droplet Soaking into 2D Cell Culture" has been posted to arXiv. This paper presents our group's first experimental work with bacteria where we develop a model for liquid droplets soaking into an agar plate. We derive a channel response to describe the molecule dynamics within the agar and the molecules that get absorbed by bacteria growing on top of the agar. We use a basic experiment to estimate the droplet soaking parameters and use particle simulations for the diffusion and absorption processes. This work will be the foundation for us understanding how signals can propagate within and between surface bacterial communities. The paper was co-authored with Christophe Corre (University of Warwick School of Life Sciences and Department of Chemistry).

New CFP - Molecular Communication in Crowded and Multi-Cellular Environments

We are pleased to announce an upcoming special issue in IEEE Transactions on Molecular, Biological, and Multi-scale Communications, entitled "Seeing Through the Crowd: Molecular Communication in Crowded and Multi-Cellular Environments". You can find the full CFP on the T-MBMC websiteLink opens in a new window. Please consider submitting to the issue and sharing this call with your collaborators.
We do welcome contributions from authors outside of IEEE/ComSoc. To facilitate this, initial submissions do not need to follow the IEEE formatting guidelines, as long as the scientific and technical ideas are conveyed clearly.
In short, the aim of this Special Issue is to raise a spotlight on the diversity of complex environments and the tools that are needed to describe molecular signaling and communication in these systems. We have a particular interest in biophysical models that have not yet been subject to extensive molecular communication analysis, but contributions using any models that are appropriate for “large” cellular systems are welcome.
The list of invited topics includes (but is not limited to) research articles and surveys on the following:
  • Signal propagation models designed for intercellular environments such as organoids, tissues, organs, tumors, and biofilms
  • Signal propagation models designed for intracellular environments such as cytoplasm, nuclei, and organelles
  • Signal propagation models designed for crowded environments (biological or non-biological) such as porous media
  • Unconventional diffusion modeling, including anisotropic diffusion, anomalous diffusion (superdiffusion or subdiffusion), fractional Brownian motion, and multi-phase diffusion
  • Biophysical flow modelling, including turbulent and laminar flow
  • Multi-cellular chemical reaction networks
  • Design of synthetic or natural communication systems in multi-cellular environments
  • Communication system analysis in multi-cellular environments
  • Decentralized cellular decision-making and computation
  • Experimental methods to apply or detect signals in multi-cellular environments, either in aggregate or at single-cell resolution

Manuscript Submission Deadline: 15 September 2023
Publication Date: March 2024

Paper Accepted: Diffusive Molecular Communication with a Spheroidal Receiver for Organ-on-Chip Systems

Our paper "Diffusive Molecular Communication with a Spheroidal Receiver for Organ-on-Chip Systems" was accepted for presentation at IEEE ICC this May in Rome, Italy. This paper will be our group's first publication focused on organ-on-chip systems. We model an organoid of cells as a receiver and derive the channel response from a nearby point transmitter. We approximate the porous organoid receiver as a sphere with a lower diffusion coefficient and show its impact on the received signal. This paper was co-authored with Hamidreza Arjmandi and Mitra Rezaei from our group, in addition to Mohamad Zoofaghari (Yazd University, Iran) and our SIMBA project collaborators at AstraZeneca Sweden (Kajsa Kanebratt, Liisa Vilen, David Janzen, and Peter Gennemark).

Paper Accepted: Membrane Fusion-Based Transmitter Design for Static and Diffusive Mobile Molecular Communication Systems

Our paper "Membrane Fusion-Based Transmitter Design for Static and Diffusive Mobile Molecular Communication Systems" (alternative arXiv link) was accepted for publication in IEEE Transactions on Communications. This paper considers a novel molecular communication system where the transmitter is a membrane-bound sphere and vesicles bind to and fuse with the sphere in order to release molecules into the propagation environment. Such a system is more reflective of cellular signalling than the point- or volume-based transmitters that are usually modelled. We derive the resulting molecule release probability and the corresponding impact on what is observed at an absorbing receiver. Our simulation results show how the hitting probability at the receiver is impacted by slow vesicle diffusion or a low membrane fusion probability. The paper was co-authored with Xinyu Huang (Australian National University), Yuting Fang (Melbourne, Australia), and Nan Yang (Australian National University).
