These methods help detect low-abundance biomarkers, which is crucial for early disease diagnosis. Improved signal detection allows for more reliable test results in healthcare and research. These advancements are shaping the next generation of highly sensitive immunoassays, making them more accurate and efficient.
• Lateral Flow Immunoassays (LFIA): Lateral flow immunoassays (LFIA) are gaining popularity due to their affordability and ease of use. They deliver quick results, making them ideal for point-of-care testing. Researchers are now enhancing their sensitivity and accuracy. New materials and improved detection methods are making them more quantitative. This means they can now provide measurable results instead of just positive or negative readings. With better performance, LFIAs are being used in infectious disease diagnosis, pregnancy testing, and even cancer detection. Their growing reliability ensures broader adoption in both clinical and home settings.
• Digital Microfluidic Platforms: Digital microfluidics is revolutionizing immunoassay technology. These systems allow precise control of tiny liquid samples, improving efficiency.
