Functionalized Gold Nanoparticles As Optical Nanosensors For Determination Of Aluminum (iii) Ions In Water Samples

Over the last decade, researchers have paid more attention to gold nanoparticles (AuNPs) due to their unique optical properties that can be used for a nanosensor platform based on colorimetry and fluorescence detection. AuNPs are developed via functionalization as a sensing element based on colorimetric or fluorimetric detection for the target analyte, such as metal ions in water samples. In this chapter, we have focused on novelties of the functionalized AuNPs as sensors for Al3 + ion detection. The novel sensing approaches were discussed using functionalized AuNPs to enhance the possibility of developing nanosensors for detection of Al3 + ions that exhibit desirable characteristics, such as high sensitivity, selectivity, rapid, and simple. The recent advantages of functionalized AuNPs that highlight the reliability of their applications for detection of trace Al3 + ions in water samples are evaluated.
