The Electrochemical Engine Behind Guanine

Stackable, reversible tags and encoded electrochemical signatures
enabling ultra-low detection across hundreds of analytes from a single sample.

Electrochemistry has long promised fast, inexpensive diagnostics, but traditional sensors could only detect redox molecules or simple redox tags—leaving most of modern medicine out of reach. Early attempts to expand capability through DNA oxidation failed because the DNA itself decomposes, creating unstable signals and making multiplexing impossible.

Guanine overcomes this foundational limitation with reversible quadruplex redox tags that remain intact through repeated measurements and can be loaded by the thousands or millions onto a magnetic particle. This transforms electrochemistry into a broadly applicable detection engine with any ligand type, capable of measuring proteins, nucleic acids, metabolites, redox species, and even whole cells through a single, low-cost interface.

This universal chemistry forms the base of Guanine’s next-generation signal architecture. On top of it, Guanine integrates two major breakthroughs—Composite Multiplex Encoding (CME) and Adaptive Multi-Domain Waveform Control (MDWC)—that dramatically extend the platform’s range, sensitivity, and multiplexing capacity. Together, these systems allow Guanine to uniquely separate, identify, and quantify hundreds of signals that would otherwise overlap.


⭐ Core Technology Overview

Multi-omic multiplex architecture

Guanine’s universal chemistry and signal-engineering architecture: magnetic particles loaded with reversible tags create strong amplified signals; CME and MDWC decode and extract multi-omic information with extreme sensitivity, precision, and multiplexing.

Without exposing proprietary algorithms or waveform structures, these innovations turn a simple, inexpensive electrochemical reader into a multi-omic, extreme-plex diagnostic engine. The result is a platform capable of addressing use cases traditionally served by multiple legacy technologies (PCR, immunoassay, metabolomics) with faster turnaround times, lower cost, and seamless adaptability across clinical and OEM applications including sepsis, oncology, neurology, cardiology, infectious disease, and precision health.


⭐ Technical Pillars

Six Core Technology Pillars

Six core technology pillars power Guanine’s competitive advantage: a unified architecture that integrates breakthrough chemistry with advanced signal engineering to deliver rapid, culture-free, multi-omic analysis at multiplexing and sensitivity levels unattainable by traditional platforms. Each pillar contributes independently to performance, while together forming a tightly integrated diagnostic engine.
