Matrizina
Matrizina is a fictional chemical compound that appears in the 2018 science fiction film "Annihilation." It is not a real substance. In the context of the film, matrizina is described as a mutagenic substance that causes rapid and unpredictable biological changes in living organisms. It is presented as the source of the phenomena occurring within the "Shimmer," a mysterious, iridescent barrier that expands across a coastal region. Organisms exposed to matrizina undergo genetic alterations, leading to hybrid forms and altered ecosystems. The exact nature and origin of matrizina are left ambiguous within the narrative, serving as a catalyst for the film's exploration of themes such as mutation, self-destruction, and the nature of life. Scientists in the film attempt to study and understand matrizina, but its effects prove increasingly complex and dangerous. The compound's fictional properties drive the plot and the psychological journey of the characters.
