We search nature for proteins that can sense.

Orbion is building Nebula to find natural proteins for quantum sensing. A protein whose emitted light changes with an applied magnetic field could help distinguish a reporter from fluorescent background.

We connect structural discovery, detailed physics and independent experiments. With Qnity, we are also developing a separate electrical readout.

We search molecular structures for reactions worth testing.

Some proteins hold a cofactor, a small molecule that takes part in their chemistry. Its surroundings influence how electrons move and which reactions follow.

Nebula searches flavin binding enzymes and electron transfer proteins. Structural checks and inexpensive calculations narrow the search. Detailed models will test whether structure can predict a useful spin response before an independent sensing experiment.

Read the discovery rationale

A magnetic field can change how a radical pair reacts.

Light can initiate electron transfer, creating two radicals with unpaired electrons. Electron spin is a quantum property that affects which reactions this pair can undergo.

In suitable systems, a magnetic field changes the reaction balance and the emitted light. Published protein experiments establish this starting point for Nebula’s search. Abrahams et al., 2026 ↗ · Meng et al., 2026 ↗

Structural screening has run. Independent tests come next.

Our discovery engine has completed structural screening with inexpensive physical checks. We are developing models of electron transfer and spin dynamics for individual proteins.

Independent electron paramagnetic resonance measurements will test the predicted radical states. Separate optical and electrical experiments will establish whether the response repeats across preparations and improves a measurement.

Read our current progress and next tests

Magnetic modulation could distinguish a reporter from background light.

A microscope collects light from the reporter and its surroundings. Changing a reporter’s fluorescence with a magnetic field can help distinguish its signal from background, as published protein experiments show. Abrahams et al., 2026 ↗

A first study would test this possibility in a purified candidate, against an existing reporter under matched illumination, buffer and observation time.

Read the proposed comparison

An electrode could read a protein’s response to light.

With Qnity, we will test proteins attached to an electrode during repeated periods of light and darkness. We will look for changes in capacitance, impedance or current beyond the electrode’s own response.

A repeatable electrical response would establish that the interface responds to light. Detecting magnetic or biochemical change would require a separate calibrated comparison.

Read the electrical approach and its limits

Each experimental result will change what we test next.

We will compare each result with a prediction recorded for the same protein and conditions. Disagreement will guide revisions to the model and the choice of another protein or experiment.

The next test must resolve a remaining uncertainty and address the original measurement requirement. Results that reject a candidate are part of this discovery process.

See how experiments will guide discovery

We are developing paid protein discovery studies.

We are developing studies for microscopy and bioelectronics teams. Tell us where your current method falls short, such as fluorescence obscured by background light or a molecular response you want to read electrically.

A paid study would test one measurement requirement.

Preliminary tests would establish whether a candidate merits comparison with your current method. A paid study would deliver preparation methods, predicted and measured performance, and reproducible analysis.

A pilot would test the protein with your equipment.

We would check whether the response remains useful with your instrument, routine samples and operating conditions.

Reliable results could support a licence.

Repeat studies and licensing could make the discovery workflow or a validated sensing application part of your product development.

Discuss a first study

Protein sensors could help us follow living systems as they change.

Five application hypotheses guide our longer term research. Each depends on a protein response that can be measured reliably in the intended setting.

Monitor the muscle in a biohybrid robot.

A molecular signal could link the muscle’s condition to its mechanical output.

Studies and proposed tests

Nebula is built by Orbion.

Orbion develops computational tools for protein expression, stability and developability. With Nebula, we are extending that work into the discovery of natural protein quantum sensors.
