The meaning of 'microinjection' is clearly based on 'injection' with 'micro-' meaning very small, but the exact laboratory technique is specialized.

Etymology

The word microinjection comes from micro- meaning 'small', a part you see in words like microscope and microphone, and from inject or injection meaning 'to put in'. So, microinjection literally means 'putting small things into' something, which is why it names the laboratory method of putting tiny bits directly into a cell with a very fine needle.
