“Nanobot” is a diegetic prototype envisioned in a possible near future—approximately a century from now—when air pollution has gotten out of control, and humans can no longer step outdoors without an oxygen kit. This project is a speculative and critical design of the anticipated technology; it showcases the tech’s effects on society, its potentials, and its flaws through the art of storytelling, with the state of the current world and a number of promised technologies set as the project’s backbone.
