84. Dirt™

Pound-for-pound the most popular nanoswarm in the system, it is Dirt™ that allows Earth's plant-life to flourish on Mars, just as it once served as the backbone for the Saharan reclamation projects. Dirt™ can be mixed into hydroponics, mixed into soil, or even serve in place of soil, all while acting as simple medichines for plants. Dirt™ will kill harmful microbes, support beneficial microbes, sequester toxins, hold water, accelerate composting, and deliver nutrients, seeing to it that your plants' health is served from the molecule up.
