Start sourcing today: a path for students and tiny startups
You don’t need a factory to start. You need a design you can test cheaply, a mentor or facility, and a bill of materials. Here is a realistic path.
Step by step
- Simulate or design first, for free. Use caDNAno or scadnano for DNA, the oxDNA web server to check a design, nanoHUB for simulations, and KiCad or FreeCAD for hardware.
- Build a tabletop analogue. Magnet tiles, bristlebots, floating capillary tiles, and pipe-cleaner bundles teach the same ideas as the lab versions. See Experiments.
- Write a bill of materials (BOM). One row per part: quantity, vendor link, lead time, hazard note. Mark each row buy / borrow / print / skip. See the starter BOMs.
- Find access, not equipment. A school teacher, university outreach office, makerspace, or community lab can open doors. US students and startups can look at NNCI sites , which serve outside users.
- Order through the institution. Research reagents (oligos, proteins, nanoparticles) usually ship only to a lab address with a responsible person.
- Build ten, not a thousand. Make ten reliable units and measure how often they assemble correctly before you scale.
- Outsource the hard steps. PCB fabs, 3D printing services, MPW foundry runs, and shared microscopes let a tiny team act like a big one.
Which domain should you start in?
| If you have… | Start with | Why |
|---|---|---|
| A 3D printer and a soldering iron | Modular and swarm robots | Every part is hobbyist-available |
| A laptop only | DNA nanotech design | Design tools are free |
| A school lab with a microscope | Colloids and active matter analogues | Optical microscopy works above 1 µm |
| A university mentor | Any domain, plus characterization access | Unlocks reagents and facilities |
For a startup
- Your first customers will mostly be other labs: designs, reagents, kits, software, and services, not finished self-assembling products.
- Budget for lead time (weeks for oligos and PCBs, months for MPW runs) as carefully as for money.
- Expect suppliers and regulators to ask about safety and end use. Read Safety and regulation early.
