  Interference alignment (IA) is a promising scheme to increase the throughput
of the system with shared mediums. In this paper, we propose a novel IA scheme
in molecular interference channels (IFCs) based on the choice of
releasing/sampling times. To cancel the aligned interference signals and reduce
the signal dependent noise, we use molecular reaction in the proposed IA
scheme. We obtain the feasible region for the releasing/sampling times in the
IA scheme using reaction. Further, we investigate the error performance of the
proposed scheme. Our results show that the proposed IA scheme using reaction
improves the performance significantly.
