How is Check4™ different from other pathogen tests?

The Pandemic has taught the public much about medical testing, its limitations and effectiveness. Check4™ by IdentifySensors, is not a PCR test, an antibody test or an antigen test. These are all outdated technologies developed 50 years ago, yet they still make up the vast majority of testing for infectious diseases today.

Check4™ is new patented technology that moves medical testing from a chemical reaction to a digital readout. It uses electronic nanosensors to measure precise levels of micro-electric currents that pass through viruses and bacteria. Each disease carries a digital signature, which now can be quickly identified in saliva and decoded through a small portable reader. When used, the reader transmits results wirelessly to the user’s smartphone in minutes.

In May 2021, this proprietary and patented technology moved from development stages at Purdue University to the commercialization stage, where new devices soon will be manufactured by the millions for governments, health care systems and corporations.

INVESTMENT OVERVIEW

IdentifySensors Biologics and Purdue University have partnered to create Check4™ — a highly accurate, over-the-counter device intended for anyone quickly self-test for multiple diseases. Anywhere, anytime.

The system is a major breakthrough because it does not rely on the current chemical-based hospital tests developed 50 years ago. Instead, patented nanosensors electronically pinpoint viruses and bacteria with ultra-high accuracy in minutes. The system requires no doctors, labs or high costs. Tests are performed entirely at home or on the go. Results appear on a smartphone in about 10 minutes.

Each test cartridge is intended to cost less than $25. This patented technology is close to FDA EUA approval. However, IdentifySensors has started marketing the product to corporations and governments that do not require FDA approval for testing their employees or citizens.

This new digital technology is intended to significantly disrupt the $50-billion chemical testing industry. It is intended that consumers soon will have a testing laboratory in their home medicine cabinets to test for multiple diseases.

In Partnership with Purdue University

When IdentifySensors developed the concept for digital disease testing, the company knew it needed a world-class academic institution to verify the discovery and move the technology to the next step.

In 2019, IdentifySensors partnered with the world-renowned Department of Inflammation, Immunology and Infectious Diseases at Purdue University. The department’s leading scientists have personally overseen the research and have served as company advisors ever since.

In the spring of 2021, IdentifySensors moved the technology from the research lab the commercialization stage, where the work as Purdue is being optimized for large-scale, roll-to-roll manufacturing.

Proprietary and Patented Technology

Years ago, IdentifySensors began developing and patenting nanosensors that detect pathogens that grow in food during long-distance transport. When the pandemic struck, scientists turned their research to a rapid COVID test based on the same technology.

Soon into the development stage, researchers realized the technology could serve as an all-new disruptive platform that could forever change the medical testing industry. Check4™ currently has several utility patents, with others pending.

Why this Breakthrough is Significant

Disease testing has remained essentially unchanged for the past 50 years. The pandemic exposed that current methods can be clumsy, slow and inefficient. By moving the testing from a chemical-reaction model to a digital readout, IdentifySensors is projected to significantly disrupt the $50 billion diagnostics industry that will make most existing tests obsolete.
