Cancer is one of the most lethal diseases and has distinct variants that affect over 60 organs in human body. The necessity advanced methodologies for early diagnosis cancer grown past decades. Among various biomarkers, microRNAs (miRNAs) have emerged as highly specific minimally invasive indicators detection, prognosis, treatment monitoring. Their stability biological fluids their critical role gene regulation make them valuable targets diagnostic applications. Plasmonic biosensors gained massive attention owing to unique optical properties, such surface plasmon resonance, making promising tools sensitive selective analysis cancer-associated biomarkers. In contrast previous reviews, this work offers a comprehensive overview advancements from approximately five years, particularly detection miRNAs. It emphasizes emerging plasmonic sensing strategies, integration with novel nanomaterials, enhanced signal amplification techniques. By focusing on these recent innovations, review provides new insights into potential improve treatment.
