What does biohacker mean?
A biohacker is someone who brings the experimental, do-it-yourself ethos of computer hacking into the realm of biology. The term covers a spectrum of activity: some biohackers work in community laboratories or their own homes, running genetic experiments with affordable equipment; others focus on 'self-hacking', using implants, supplements, wearables, and rigorous data collection to enhance their own physical or mental performance. The word blends 'bio-', from the Greek bios meaning life, with 'hacker', evoking both technical cleverness and a disregard for conventional gatekeeping. Biohackers are generally amateurs working outside universities and corporations, which makes the term carry connotations of both democratic science and potential risk — regulators and ethicists have debated whether such unsupervised experimentation is safe. The word is informal to neutral in register and appears frequently in technology journalism, where figures like Josiah Zayner have become well-known representatives of the movement.
nounA person who applies the methods and mindset of hacking—experimentation, improvisation, and do-it-yourself ingenuity—to biology, often conducting experiments on their own body or with low-cost equipment outside traditional institutions.
- A member of the DIY biology movement who conducts biological experiments outside formal institutions, often using inexpensive or repurposed lab equipment.
- A person who uses technology, implants, supplements, or data tracking to modify or optimize their own body and performance.
"The biohacker tracked her glucose levels continuously, treating her own metabolism as an open-source project."
"In a rented community lab space, the biohacker sequenced a strain of bacteria she had cultured at home."
"Silicon Valley biohackers swear by fasting regimens and wearable sensors that monitor every metric of their health."
Regular plural; used freely in both countable and collective senses.
"Biohackers gathered at the conference to share open-source protocols."
Some biohackers have implanted magnets and RFID chips in their own bodies — turning themselves into walking experiments.

Etymology of biohacker
The word 'biohacker' is a compound of 'bio-', from Greek bios ('life'), and 'hacker', a term that emerged from American computing culture in the 1960s–70s to describe a skilled, resourceful programmer. It arose in the late 2000s and early 2010s alongside the DIY biology ('DIYbio') movement, when cheap gene-editing tools and open-source protocols made home laboratory work feasible. Its cognates include other 'bio-' compounds such as biopsy, biography, and symbiosis, all drawing on the same Greek root.

How biohacker is actually used
The term is informal to neutral in register and carries mixed connotations: it can suggest admirable ingenuity and scientific democratization, but also recklessness or unsafe experimentation. In journalistic and academic contexts it is often paired with qualifiers such as 'garage', 'amateur', or 'grinder' (for implant enthusiasts).
Easily confused with biohacker
A bioterrorist deliberately uses biological agents to cause harm, whereas a biohacker experiments with biology out of curiosity or self-improvement, usually without malicious intent.
