Solutyppi

Solutyppi is a term used in speculative biology and science fiction to denote a hypothetical class of engineered cellular-scale transport devices that mediate selective movement of solutes across biological membranes.

The word solutyppi appears to be a constructed term; in the fictional works where it is used, it combines “solu-” from solute or cell-related language with a suffix “-typpi” that marks a category or type.

In the imagined design, solutyppi are nanoscale assemblies embedded in membranes, consisting of a programmable core, selective gates, and an energy-coupling mechanism that leverages ion gradients or similar energy sources to drive transport. They are described as capable of recognizing specific solutes and adjusting transport rates in response to cellular conditions.

In narrative contexts, solutyppi is used to explore themes of autonomy, safety, and ethical regulation of powerful transport technologies; real-world scientists tend to treat it as a thought experiment rather than a real molecule. The concept is sometimes employed to illustrate discussions around membrane transport, energy use, and the potential societal impact of advanced nanotechnologies.
