Nanotechnology has emerged as a transformative force in biomedical research, offering unprecedented capabilities for bioanalysis. Its inherent properties allow for enhanced sensitivity, specificity, and the ability to conduct multiplexed analyses, which are crucial for advancing diagnostics and therapeutic strategies. Nanomaterials, including nanoparticles, quantum dots, and nanowires, serve as fundamental components in the construction of sophisticated biosensors. These nanosensors facilitate the early detection of disease biomarkers, a critical step towards effective disease management and personalized medicine [1].
