System overview
From Levskyaya et al.
| "We have designed a bacterial system that is switched between different states by red light. The system consists of a synthetic sensor kinase that allows a lawn of bacteria to function as a biological film, such that the projection of a pattern of light on to the bacteria produces a high-definition (about 100 megapixels per square inch), two-dimensional chemical image." |
Sample photos
Here are a selection of sample coliroid taken with the bacterial photography system.

Device implementation
This system consists of two devices.
- A light sensor which takes red light as an input and produces PoPS as an output.
- A color generator which takes a PoPS signal as input and generate color as an output.

Parts implementation
This diagram shows the list of parts that make up each of the two devices.
