In this study, the localized surface plasmon resonance (LSPR) effects of Au nanoparticles (AuNPs) modified on glass substrate were used for glucose sensing. AuNPs were fabricated by using photochemical method, then the AuNPs film was prepared by using self-assembly method. Finally, AuNPs film was used to detect the different concentrations of glucose solutions. The result shows obvious peaks of absorbance...
This study presents a novel biochip containing a gold-nanoparticles modified quartz crystal microbalance (nano-Au-QCM) sensor and a piezoelectric transducer which enhances performance by production of ultrasonic standing waves (USW). Biotin-streptavidin binding is used as a model in experiments with the developed biochip to verify that nano-Au-QCM and USW enhancement greatly improves biochip detection...
