In a way that does not involve biological processes or living organisms.
The experiment was conducted nonbiologically to avoid any interference from living cells.
Nonbiologically → It is formed from "non-" (meaning not) and "biologically" which comes from "bio-" (from Greek "bios", meaning life) and "-logy" (from Greek "logia", meaning study of). The word refers to something that is not related to the study of life or biological processes.
Think of 'not' ('non-') related to 'life' ('bio-') and the 'study of' ('-logy') — that's why nonbiologically means not related to biological processes.
