However, most theoretical results predict more simple, ordered shapes, such as single-particle width chains. To account for this discrepancy we have created a theoretical model that phenomenologically includes the bridging or \"stickiness\" between ligands on nearby nanoparticles. This interaction is accounted for through a unitless stickiness parameter c that can be varied between 0 (no bridging between ligands) and 1 (irreversible bridging or sticking together on impact).
