Abstract

The plasmonic sensor has been developed for the detection of toxic materials in solution form. This system consists of a light source that is connected to a fiber optic duplex system with two arms. The first arm transmits light from the light source beam to the sample and the second arm sent the reflected light from the sample to the spectrophotometer. The sensing process was done in the sensor chamber made from Teflon with a sliding sample drawer is used to place the sample or known as sensing material. OOIBase32 was used to analyze the recorded spectrum from the spectrophotometer. In this study, the testing of the plasmonic sensor was carried out using targeted analyte namely boric acids with deionized water that is set as a reference medium. Two gold nanoparticles shapes which are gold nanosphericals and gold nanoplates were used as sensing materials. As a result, it was found that the plasmonic sensors with the gold nanoparticles as their sensing materials are sensitive toward the presence of targeted analyte. The sensing parameters are based on changing of their resonance peak position and its intensity.
