Consistent with the collisional mechanism that we have proposed, the performance of the M.HhaI and TBP sensors are sensitive to probe packing density on sensor surface. For example, while maximum signal suppression is obtained for the TBP sensor (left) at very low probe densities, the optimal density for the M.HhaI sensor (right) is achieved at intermediate densities.
