The Principle of Nanomaterials Based Surface Plasmon Resonance Biosensors and Its Potential for Dopamine Detection

Abstract: For a healthy life, the human biological system should work in order. Scheduled lifestyle and lack of nutrients usually lead to fluctuations in the biological entities levels such as neurotransmitters (NTs), proteins, and hormones, which in turns put the human health in risk. Dopamine (DA) is an extremely important catecholamine NT distributed in the central nervous system. Its level in the body controls the function of human metabolism, central nervous, renal, hormonal, and cardiovascular systems. It is close… Show more

“…Various types of prepared thin films can give different refractive indices that then will affect the resonance intensity [ 69 , 70 , 71 , 72 , 73 ]. This method has been widely applied in food control, environmental monitoring and drug delivery with outstanding repeatability and reproducibility [ 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 ]. Due to their superior performance, SPR sensor is gaining more attention in detecting insecticides.…”

“…In addition to the successes found using PNPs for the detection of AChE and Aβ, PNPs have also been widely employed to determine the concentrations of other AD hallmarks (e.g., dopamine, fetuin B, tau, etc.) for early AD diagnosis and prediction [22,57,[61][62][63][64][65][66][67][68][69][70][71]. The concentration of dopamine is considered to be a critical AD indicator [62][63][64][65][66].…”

“…The detection of hybridization can be obtained through changes in the electrochemical properties or changes in the optical properties due to nonspecifically adsorbed target molecules. The physical absorption of DNA target molecules can be monitored with the surface plasmon resonance (SPR) method [1][2][3][4].…”
