A Closer Look at Plasmonics

Chapter 1- Plasmonic Sensor for Detection of Biomolecular and Medical Diagnostics

A. R. Sadrolhosseini, S. Mehri Hamidi and S. Akbari

The plasmonic sensor is a versatile technique to recognize biomolecular and toxic chemicals. The plasmonic sensor can display the interaction of biomolecules with biomarker and linker. The biomolecules including DNA, RNA, antibodies, enzyme, and blood sugar can interact with biomarkers, bio-linker, and nanostructures such as gold and silver. The plasmonic sensor can detect the biomolecules and it is an accurate and reliable technique to recognize them. The plasmonic sensor is capable to investigate the interaction of biological cells with antibodies, enzymes, electrolytes, and hormones in the blood and other body fluids, and can detect the IgG (the main type of antibody that can be found in blood and extracellular fluid). Hence, the plasmonic sensors can sense and diagnose the hepatitis antigen, diabetes, leukemia, and cancer. In this study, a brief history of the plasmonic sensor, the analytical method to analyze the plasmonic signals, and the application of plasmonic sensor for displaying DNA, RNA, antibodies, sugar hepatitis, diabetes, leukemia, and cancer have been presented. Recently, the plasmonic sensor is a powerful and accurate method to investigate the brain activity and the neuroplasmonic is an interest intent issue. Hence, the plasmonic senor and the detection of brain enzymes have been considered in this chapter.
