Overview

Biosensing is under pressure to deliver faster, more reliable, and cost-effective diagnostics, but the materials behind it are limiting progress. Noble metals, graphene and screen printed carbon increase costs, create supply chain risks, and struggle to scale, slowing innovation when manufacturers need to accelerate development.

iGii has developed Gii, a breakthrough 3D carbon nanomaterial designed to replace traditional sensing materials whilst delivering superior sensitivity, cost efficiency, and scalability. With its large surface area, natural antifouling properties, and high electrochemical activity, Gii provides manufacturers with a high-performing, commercially viable alternative to noble metals.

More on Gii Sens

Unlike traditional materials, Gii can be manufactured anywhere with electricity, eliminating reliance on mined or geopolitically sensitive resources.

It offers fast electrochemical response, high reproducibility, and multi-analyte detection, making it ideal for next-generation sensing applications across healthcare, veterinary diagnostics, water quality, environmental monitoring and food safety. With our proof-of-concept sensing platform, manufacturers can validate, test, and integrate Gii seamlessly, reducing risk and accelerating time-to-market.

Use the Gii Assay to test performance, validate fit, and move faster toward integration.
