Surface plasmon resonance (SPR) has emerged as a powerful technique with significant potential for disease diagnosis. By leveraging the interactions between biomolecules, such as antibodies and antigens, SPR enables the label-free and real-time detection of disease markers in complex biological samples. It has been extensively utilized for studying protein-protein interactions, DNA hybridization, drug-target interactions, and even the detection of pathogens and pollutants. Surface plasmon resonance continues to push the boundaries of scientific understanding and paves the way for groundbreaking discoveries in the nanoscale realm.
SPR-based biosensors offer several advantages for disease diagnosis. They provide rapid and sensitive detection of biomarkers, allowing for early disease detection and monitoring of treatment efficacy. The label-free nature of Surface Plasmon Resonance eliminates the need for time-consuming and expensive labeling processes, making it a cost-effective and efficient diagnostic tool. The versatility of SPR enables the detection of a wide range of diseases, including infectious diseases, cancer, cardiovascular disorders, and autoimmune conditions.
By integrating SPR with microfluidic systems, point-of-care testing and multiplexed analysis can be achieved, bringing the benefits of SPR-based diagnostics to resource-limited settings. As research continues to advance, surface plasmon resonance holds immense potential for transforming disease diagnosis, enabling personalized medicine, and improving patient outcomes.
