⭐ A New Detection Standard
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.
