Summary
Monitoring HIV-1 viral load is crucial for antiretroviral treatment (ART). New microfluidic and nanotechnology approaches offer low-cost, rapid point-of-care (POC) tests for resource-limited settings.
Area of Science:
- Virology
- Biotechnology
- Public Health
Background:
- Commercial HIV-1 RNA viral load assays are standard for ART monitoring but require extensive infrastructure, limiting use in resource-limited settings.
- Existing alternatives like p24, RT, and in-house RT-qPCR assays are often time-consuming, complex, and unsuitable for point-of-care (POC) use.
Purpose of the Study:
- To review current HIV-1 viral load monitoring technologies.
- To discuss emerging microfluidic and nanotechnology-based approaches for developing simple, rapid, and low-cost POC HIV-1 viral load assays.
Main Methods:
- Literature review of state-of-the-art HIV-1 viral load monitoring technologies.
- Analysis of recent advances in microfluidics and nanotechnology for diagnostic applications.
Main Results:
- Current commercial assays are effective but inaccessible in many regions.
- Alternative methods have limitations in speed, complexity, and suitability for decentralized testing.
- Microfluidics and nanotechnology show promise for developing next-generation POC viral load assays.
Conclusions:
- There is a critical need for accessible HIV-1 viral load monitoring in resource-limited settings.
- Emerging microfluidic and nanotechnology platforms offer a viable path towards affordable and rapid POC HIV-1 diagnostics.
- These advancements could significantly improve ART management and patient outcomes globally.
