WHAT WE DO

Guanine’s electrical smart phone tests and AI tools accurately detect and diagnose infections in minutes

Consumer enters symptoms
on a smart phone, and
AI algorithm recommends
a specific test if warranted

Consumer collects sample
and inserts into cartridge
that is tested with
a smart phone adapter

AI algorithms provide a
preliminary diagnosis for
consumers and doctors who
can treat by telehealth

OUR INNOVATION

Guanine transforms current detection applications from optical to electrical

Guanine has invented a synthetic DNA detection tag that enables electrical detection of low level pathogens. Millions of synthetic DNA (aka oligonucleotides) fit on a microparticle with ligands that captures targets for detection, then forms sandwiches on a sensor electrode. When voltage is applied a burst of electrons is given off to produce a current peak proportional to the target’s concentration. This allows fast and accurate detection of infective pathogens with an inexpensive mobile smart phone potentiostat as used in measuring glucose concentrations. 

Guanine's technology amplifies detection signals by attaching millions of tags instead of replicating millions of copies to provide accurate results in a rapid, simple and inexpensive test. The technology can detect nucleic acids, proteins and microbes in minutes using a mobile test; provide quantitative results for microbes and antibodies; and detect up to 24 targets from a sample.
