The design and analysis of the resulting system can potentially be simplified to a few key functions and requirements by using these standardized BioBricks. With these benefits,BioBricks makes it possible for users to create several distinctive characteristics of the system. For instance, Bio-Bricks of the Las quorum sensing system, a cell-cell communication device created in iGEM 2011, were used as basic components of a positive feedback system between two engineered bacteria species in iGEM 2012 [8, 9]
