This web feature image illustrates a two-stage process. First, the microRNAs (seen in pink) bind to peptides (seen in blue). The paired particles are then encased in a hydrogel matrix (seen at the bottom of the image) which can be applied to tissue surfaces via a spray or syringe. The peptides help deliver the microRNAs directly into residual cancer cells to kill them.
