Preparation of Au Nanostructure Arrays for Fluorometry and Biosensors Applications

摘要

The paper describes the fabrication of random and ordered gold nanostructure arrays (NSA) of differentudmorphology using island film thermal annealing and nanoimprint lithography techniques. Structuraludparameters of obtained NSA were investigated using atomic force microscopy method. Spectral characteristicsudof obtained NSA were studied in air atmosphere, and NSA light extinction spectra exhibited an expressedudplasmon peak. Spectral position of localized surface plasmon resonance can be tuned depending onudgeometrical parameters of nanostructures, which is an important factor for resonant investigation methodsudof various types of molecular structures. Proposed technological approaches can be used to implement theudresonance fluorometry in electromagnetic field of nanostructures (surface-enhanced fluorescence) methodudand in chemical and biosensors based on localized surface plasmon resonance.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34962
