Living matter also performs computation. Recent years have featured a rise in the exploration of the inherent information processing capabilities of biological material as a foundation for computing systems. Biocomputing is the use of biological components, such as DNA, proteins, and cells, to perform calculations, similar to a traditional computer, but on a molecular scale. This technique offers an entirely new way of encoding and processing information, yielding some improved capabilities compared to traditional architectures, such as massive parallelism and energy efficiency. Although still an experimental field with technical challenges to be overcome (e.g., speed, scalability), research related to biocomputing is expected to continue, with this approach getting closer to real-world applications, especially in healthcare, in the next decades.
