In this work, we investigated the fabrication of surface plasmon resonance (SPR) nanosensor using gold nanoparticles (AuNPs) chemisorbed onto self assembled monolayer of 10-(3-amino phenoxy) decane-1-thiol on gold substrate. The fabrication process of SPR nanosensor was characterized using different techniques such as infrared reflection-absorption spectra (IRRAS), xX-ray photoelectron spectroscopy (XPS), and atomic force microscope (AFM). The fabricated SPR nanosensor was used for detection of Cu 2þ in an aqueous solution using surface plasmon resonance refractometer. The results confirm the fabrication of new SPR nanosensor. The fabricated SPR nanosensor showed a good activity toward the detection of Cu 2þ . The detection of Cu 2þ in an aqueous solution using the fabricated SPR nansensor was enhanced in the presence of gold nanoparticles.

“…However, SPR biosensors are unable to detect extremely small change in refractive index, which has reduced development in fields needed very high sensitivity. Several sensitization materials have been applied to overcome this problem, such as the biotin-avidin system (Birkert et al 2000), titanium dioxide , gold nanoparticles (Azzam et al 2009;Ko et al 2009), Ag nanoparticles (Yao, Zhang, and Yin 2012), and gold-silver nanoparticles (Tu, Sun, and Grattan 2013;Wang et al 2011).…”

Two novel Fourier transform-surface plasmon resonance immunosensors were fabricated for the determination of the subgroup J avian leukosis virus. The immunosensors were based on a functionalized gold substrate and immobilized gold-silver nanoparticles. For the first immunosensor, the gold substrate was functionalized with a dense self-assembled monolayer of 3-mercaptopropionic acid through gold-sulfur bonds, and then protein A which can combine subgroup J avian leucosis virus antibody on the antigen nonbinding site was modified on the sensor chip surface via covalent bonds formed between the amino groups and the activated carboxyl groups of 3-mercaptopropionic acid. After inactivation by ethanolamine, the sensor chip immobilized the antibody by the combination with protein A to produce a sensor. For the second immunosensor, 1,6-hexanedithiol formed a self-assembled monolayer on the sensor chip surface through gold-sulfur bonds. Then gold-silver nanoparticles were immobilized on the sensor chip by gold-sulfur and silver-sulfur bonds. The modification by various reagents and determination of the subgroup J avian leukosis virus antigen were the same as in the first immunosensor. The immunosensors determined the subgroup J avian leukosis virus antigen to analyte concentrations of 659 TCID 50 · mL −1 and 1054 TCID 50 · mL −1 , respectively. The result suggested that introducing gold-silver nanoparticles to the Fourier transform-surface plasmon resonance immunosensor is beneficial to effectively improving the sensitivity of the immunosensor. Moreover, the contrast experiment presented that the immunosensors showed high specificity for the subgroup J avian leucosis virus detection.

There is an increasing interest to realize smarter sensors and actuators that can deliver a multitude of sophisticated functionalities while being compact in size and of low cost. We report here combining both sensing and actuation on the same device based on a single microstructure. Specifically, we demonstrate a smart resonant gas (mass) sensor, which in addition to being capable of quantifying the amount of absorbed gas, can be autonomously triggered as an electrical switch upon exceeding a preset threshold of absorbed gas. Toward this, an electrostatically actuated polymer microbeam is fabricated and is then functionalized with a metal-organic framework, namely, HKUST-1. The microbeam is demonstrated to absorb vapors up to a certain threshold, after which is shown to collapse through the dynamic pull-in instability. Upon pull-in, the microstructure can be made to act as an electrical switch to achieve desirable actions, such as alarming.
