Step 01 — Capture t = 0s
Capture.
Receptors on the graphene surface grab the target out of the sample — bacteria, viruses, spores, or smaller molecules.
Live · Sensor reading
Pathogens,
detected in minutes.
Not days.
We build a portable sensor for food producers. Test for Listeria right where the food is made, and get clear results in minutes instead of waiting days for the lab.

§ 01 — The shift
Time to result
<0 min
From sample to results in under fifteen minutes. Your operator does it. No lab, no shipping.
Recalls caused by Listeria & Salmonella
Two bugs drive almost half of microbial food recalls. Both are still caught days late by the standard lab workflow.
Consumers who would stop buying
One recall is enough. Most shoppers walk and don't come back. The cost of catching it late is the customer.
Today, microbial testing means shipping samples to a lab and waiting two to four days. By the time the results come back, the product has usually already shipped. We bring the test to the line, so you catch contamination before it leaves the building.
§ 02 — How the test works
A simple, 3 step workflow and results in 15 minutes.
Today's sensor is tuned for Listeria monocytogenes, built for the line, not the lab.
- Step 01 ≈ 30s
Swab where Listeria hides.
Drains, slicers, belts, surfaces. Drop the swab onto a new sensor.
- Step 02 on-site
Connect the biosensor.
Connect the sensor to the read-out system, press start. Keep the line running.
- Step 03 < 15 min
Listeria: yes or no.
Pass or fail in under fifteen minutes — before the batch ships.

§ 03 — The technology behind it
Underneath: a graphene field-effect transistor.
A graphene field-effect transistor (gFET) is a charge sensor. We add receptors that grab the target; when something binds, the signal changes. No amplification, no thermal cycling, no reagents. We target Listeria monocytogenes today, but the same chip can be tuned for other bacteria, viruses, and analytes.
Step 02 — Transduce t ≈ 02:00
Transduce.
When something binds, the electric field across the channel shifts. The chip reads it straight away as a change in current.
Step 03 — Read t < 15:00
Read.
The device turns that signal into a clear pass or fail, in under fifteen minutes from sample.
§ 04 — The science
A biosensor, made specific.
01 · Graphene as biosensor
Graphene is one atom layer thick. Every electron sits at the surface, which makes the channel sensitive to whatever lands on it. There's no bulk to drown out the signal, so even a single binding event shows up as a measurable change in conductance.
02 · Surface functionalization
The receptors are what make the chip pick out one thing and ignore the rest. We bond receptors to the graphene with a linker chemistry that holds up in real food matrices. Want to detect something else? Swap the receptor.
03 · Patented manufacturing
We've developed a low-cost way to make lab-grade gFETs at volume, cheap enough to ship as a single-use sensor. That's what lets the device sit next to the production line instead of inside a research lab.
04 · Adaptable across analytes
The same platform can answer different questions. Bacteria now, viruses next, mycotoxins after that. Re-functionalize the surface, re-validate, deploy.
