Localized surface plasmon resonance sensor of gold nonorod with improving sensitivity, method of preparing the same and method of detecting bioproduct using the same

摘要

The invention nano by modifying the aspect ratio of the gold nanorods, optimize the size and gold nanorod surface and downsized to a level, and the detection limit due to the reduced steric hindrance excellent, excellent sensitivity relates to the localized surface plasmon resonance sensor and a method of gold nano-rods having the gold nano-rods and which is formed on the surface of the gold nano-rods comprises a self-assembled monolayer, and wherein the self-assembled monolayer is a terminal thiol group, a carboxyl group and a hydroxyl group that is formed by an organic absorbent which is bonded to the feature, and localized surface plasmon of the gold nano-rods of the present invention resonance sensor is the optimized aspect ratio, has a physical property such as size, as by the gold nano-rods, and modifying the surface of an organic absorbent, enabling a reduction in the size of a nano-scale in the sensor size, and the steric hindrance in the detection sensitivity reduction can lead to a significant improvement of the detection limit. Thus, the detection of complex mixtures, the early detection of cancer, infections, and the gold nano-rods sensor according to the invention in the early prevention of neurological disorders such as may be utilized in various ways. ;
