BacMan’s two-signal biosensor
BacMan describes a prototype platform pairing a target-specific gold sensor with a low-cost digital reader for biological testing.

Field notes
The measurement architecture pairs an active, phage-coated gold interdigitated electrode with a passive dummy channel; subtracting their frequency signals is intended to suppress shared background changes, while a separate reference channel monitors the electronics. The site says the August validation used an earlier Board 6 configuration, while the pictured continuing prototype uses a compact Feather board. It also notes that each new target needs its own recognition layer and biological validation.
