If anyone cares to read my take/suggestion along this topic:
the first item required would be Injectors/syringes:
(tin ingot is either tin or iron (balancing decision); iridium plates are glass. reactor plating is blank.)
makes 8 syringes. syringes can be used to inject nanobots into your body.
nanobots are created at the:
Nanobot assembler
(iridium is glass again, power crystals are lap. crystals.)
takes up to 512 EU/t. placing raw materials into the nanobot assembler will create different nanobots depending on the ingredients. the nanobot assembler has a crafting slot for power-storage (increases duration) power-transmission (increases intensity) nanobot type (place cell here; determines effect) and raw material (determines # of nanobots created)
also in the nanobot assembler there is an output slot. syringes must go in here, and the nanobots will be placed in them when they are created. the raw material determines the number of syringes filled by the nanobots.
if you craft the quantum suit together with a syringe on each side, you will get the quantum injector suit. same capabilities, except when you use the quantum injector suit, the suit will automatically inject nanobots into you when they are needed, if the syringes are in your hotbar.
the nanobots would work very similarly to potions, though the syringes would be used instantly, rather than having to drink a potion. they would have an effect of a certain intensity, for a certain duration, that does...something. F.e. a nanobot injection that lets you jump higher and run faster, or automatically heals you (not instantly, but over time; like peaceful-mode healing, although a bit slower, and only lasts until the nanobots run out of power)
