Kevin Land | Global Access Diagnostics (GADx): How can printed electronics enable real-time data connectivity in a disposable diagnostic?

Can you develop a molecular diagnostic that costs less than $10?

Affordability is arguably the single greatest challenge in developing diagnostics for global health and pandemic preparedness. While advanced technologies may offer superior performance, their adoption is often completely blocked by cost. This constraint applies not only in low and middle-income countries but also in high-income nations when frequent, mass testing is required.

The cost targets are extremely aggressive and set by major global health organizations like the WHO. For simple antigen-based lateral flow tests, the benchmark is under $1 per test. This is driven even lower by the existing market for malaria diagnostics, where tests are available for as little as 20 US cents, creating a formidable price-performance competitor for any new technology.

For more complex molecular diagnostics, which offer higher sensitivity, the WHO has established a target price point of around $10 per test. Achieving this in a fully integrated, disposable format that includes sample preparation, nucleic acid amplification, and detection is a monumental technical challenge. It requires a fundamental rethinking of device architecture, materials, and high-volume manufacturing processes to drive the bill of materials down to a viable level.

In this short video, you can learn:
* Why affordability is the primary barrier to widespread diagnostic adoption.
* The aggressive cost targets for point-of-care tests: under $1 for lateral flow and around $10 for molecular diagnostics.
* How existing ultra-low-cost tests create a competitive landscape that new technologies must navigate.
📋 **Clip Abstract** This clip breaks down the extreme cost constraints for global health diagnostics, a critical factor for market success. Kevin Land reveals the target price points, including sub-$1 for lateral flow tests and a challenging $10 for fully integrated molecular tests.

Can we merge the simplicity of a paper test with the power of a molecular lab using roll-to-roll manufacturing?

A promising solution for next-generation diagnostics is a hybrid approach that combines the best of existing technologies. The strategy involves taking the well-understood, incredibly scalable, and low-cost lateral flow device platform and augmenting it with functional intelligence. This moves beyond a simple visual result and integrates the capabilities of more complex, equipment-based diagnostics into a single, disposable format.

The speaker explicitly identifies the printed and flexible electronics community as a key enabler for this vision, specifically citing its expertise in high-volume manufacturing. Processes like roll-to-roll and sheet-to-sheet manufacturing are perfectly suited for assembling complex, multi-layered devices at low cost. This capability is essential for integrating the various layers of functionality—fluidics, chemistry, electronics, and power—into a cohesive and affordable product.

This concept is not just theoretical; the speaker presents a tangible example of a laminated molecular diagnostic currently in development. This device functionally combines a molecular test with a simple lateral flow readout and an integrated power source. This multi-layer, laminated architecture is a prime example of how printed electronics manufacturing techniques can be used to build sophisticated, all-in-one diagnostic tests for the point of need.

In this short video, you can learn:
* A hybrid strategy: adding functional intelligence to proven, scalable lateral flow platforms.
* How roll-to-roll manufacturing is key to integrating complex functions into a low-cost, single-use format.
* A real-world example of a laminated molecular diagnostic that combines multiple technologies into one device.

He highlights roll-to-roll manufacturing as the key enabler and showcases a laminated molecular device that combines multiple functions into a single consumable.
