Practical Transmitters for MC: Functionalized Nanodevices Employing Cooperative Transmembrane Transport Proteins

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Communication Systems

Background:

• Molecular Communication (MC) systems require practical transmitter designs.
• Current MC transmitters lack precise external control over signaling molecule release.
• Vesicular nanodevices offer potential for optical-to-chemical signal conversion.

Purpose of the Study:

• To propose and model a novel optically controllable molecular communication transmitter (TX) using vesicular nanodevices (NDs).
• To enable externally controlled release of signaling molecules for advanced MC systems.
• To bridge the gap between MC theory and practical implementation through chemically realizable components.

Main Methods:

• Design of a transmitter based on functionalized vesicular nanodevices (NDs).
• Development of a general system model with two cooperating modules (energizing and release).
• Mathematical analysis of signaling molecule concentration, including buffering media and multiple NDs, validated by numerical methods.

Main Results:

• Derivation of exact and approximate analytical expressions for released signaling molecule concentration.
• Validation of the proposed model using numerical methods.
• Inclusion of the impact of buffering media and parameter randomness from vesicle synthesis.

Conclusions:

• The proposed optically controllable nanodevice-based transmitter is chemically realizable.
• The developed models facilitate system parameter optimization for future experimental realization.
• This work advances the practical implementation of molecular communication systems.
