Bit Sequence
≤10 bits
Only 0s and 1s. Each bit triggers a molecule release at its start.
count
0
Molecules released when transmitting a '0'.
count
300
Molecules released when transmitting a '1'.
%
50%
Fraction of max(mol₀, mol₁). Received count above threshold → infer the higher-molecule bit.
s
10 s
Duration of each bit period. Unreceived molecules persist (ISI).
Channel
μm
60 μm
Edge-to-edge gap between transmitter and receiver membranes.
μm²/s
70 μm²/s
Diffusion coefficient of the signaling molecule in the medium (Stokes–Einstein relation).
μm/s
0 μm/s
Bulk flow along TX→RX axis. Zero = pure Brownian motion.
Cell Geometry
μm
300 μm
Horizontal extent of the diffusion boundary.
μm
300 μm
Vertical extent of the diffusion boundary.
μm
10 μm
Radius of the transmitter cell.
μm
10 μm
Target cell radius. Larger receiver captures more molecules.

Each bit triggers a molecule release at the start of its period. Unreceived molecules persist in the channel, causing inter-symbol interference (ISI). The simulation stops after the last bit period ends.
