This document proposes a new method for detecting HIV at the point-of-care using cascade amplification of DNA probes conjugated to gold nanoparticles. The probes are designed to form hairpin structures that open upon binding to the HIV target sequence, triggering a cascade reaction and aggregation of gold nanoparticles, resulting in a color change that indicates a positive or negative result. This new method aims to provide faster, cheaper detection of HIV compared to the current PCR-based methods, in order to improve disease management. Experiments have not been conducted yet but are projected to be successful.
