Abstract: In diagnostic technologies, search for quick, accurate, and cost-efficient ways to confirm
diseases has prompted the investigation of alternative methodologies to classic PCR-based tests. This
article delves into the growing field of nanoparticle-based immunoassays, offering a comprehensive
evaluation of their potential as viable alternatives to PCR for disease diagnostics. We discuss the
basic principles of nanoparticle-based immunoassays, highlighting their distinctive ability to combine
the specialized binding characteristics of antibodies with the improved detection capacities of
nanoparticles. The article compares the performance attributes of nanoparticle-based immunoassays
with PCR, focusing on sensitivity, specificity, and detection speed. We further delve into a novel
diagnostic technology, immuno-PCR, which integrates the strengths of immunoassays and PCR
techniques. Healthcare systems and stakeholders must comprehend and implement novel diagnostic
procedures emphasizing accuracy and sensitivity as the diagnostic landscape advances globally. This
review contributes to the advancement of diagnostics by synthesizing current research and suggesting
future directions for development. It highlights the transformative potential of current and emerging
methods in shaping the future of disease diagnostics.
