Your own sentinel for estimating DNA damage

Reading the breaks
in every strand.

POLEX™ is our DNA break detection platform — powered by nanopore sequencing and AI. We map single- and double-strand breaks at base resolution. We propose to use our novel chemistry of photon oxidation, turning raw ionic signal into genome-wide damage landscapes in hours, not weeks.

About · Mission

We build at the interface of biology and engineering.

Where single-molecule genomics, deep bioinformatics, and machine learning converge to make DNA damage visible at the resolution disease actually happens.

Mission

To turn invisible DNA damage into actionable signal — giving every patient, every therapy, and every cell a clear readout of genome integrity.

Vision

A future in which DNA damage is no longer the silent driver of disease, but a measurable, interpretable, and treatable signal at the heart of every diagnosis and every cure.

Approach

Proposed photon-oxidation chemistry + long-read nanopore sequencing + deep learning, productised as POLEX™ — the first platform to map double-strand breaks at single-base resolution, genome-wide.

Application areas

DNA break detection, across the spectrum of disease.

POLEX maps chromosomal fragility in every condition where DNA damage matters — pick a domain to see the disease atlas.

POLEX™ · Proprietary Platform

Signal to break call, end-to-end.

The POLEX platform pairs nanopore sequencing with purpose-built AI to resolve DNA breaks at base resolution. See the full pipeline, the neural network, and the zoom from cell to base pair.

PIPELINE

Nanopore → calls

Signal capture, transformer basecalling, CNN break detection, genome mapping, interactive report.

AI MODELS

Three core models

NeuroBase for basecalling, BreakSeer for break classification, ContextNet for genomic context.

OUTPUT

Base-resolution break map

Single-strand breaks (SSB), double-strand breaks (DSB), complex lesions, with motif context and confidence scores.

For Investors

Pre-seed round opening.

We’ve raised £140k in non-dilutive grant funding to date — from BBSRC and the Guy Newton Translational Award via the Sir William Dunn School of Pathology, University of Oxford. We’re now opening a pre-seed round to scale the wet lab, build out the AI and clinical team, and validate POLEX across our first oncology and neurodegeneration cohorts.
