The hidden role of gold nanoparticles in Southeast Asian diagnostics
Gold nanoparticles are essential components in rapid diagnostic tests used across Southeast Asia for detecting infectious diseases like COVID-19 and dengue. These particles act as labels that translate biological interactions into visible results on test strips.
Why it matters
Understanding the role of nanotechnology in diagnostics is critical for public health infrastructure and the efficacy of rapid testing in resource-constrained regions.

Rapid diagnostic tests are used across a range of healthcare applications, including the detection of infectious diseases. Across Southeast Asia, immunochromatographic test technologies are applied to respiratory infections such as influenza and COVID-19, as well as mosquito-borne diseases including dengue, chikungunya, and Zika.
These applications have particular relevance in the region, where both respiratory and mosquito-borne infectious diseases present ongoing healthcare challenges.
Although the diseases and specimens being tested may differ, the basic challenge is similar: recognising a target and making the result visible in a practical test format.
