| Abstract: |
| Copper plays a fundamental role in a wide range of environmental and biochemical processes. However, copper is greatly toxic to the biological tissue if the concentration exceeds cellular requirements. Cu (II) ion is common hazardous pollutant and one of the most widespread heavy metal contaminants in the environment. The costly instrumentations, sampling, storage, handling, time-consuming and complicated pretreatment of common measurement methods of Cu (II) ions make them unsuitable for on-line or field monitoring. Therefore, there is an urgent demand for designing new sensors that can determine the existence of Cu (II) ions which show significant quantitative and qualitative changes in the presence of the ion. A metal ion sensor generally composes of a recognition site designed to bind the target ion and a readout system. Nanostructured silica materials are good solid bases for the fabrication of organic-inorganic hybrid materials by introducing specific functional groups into the frameworks or channels due to their abundant surfaces. Moreover, due to their nontoxicity and biocompatibility, composites based on nanostructured silica have good potential applications in biosystem. This review reports on application and efficiency of nanosensors using several nanostructured silica platforms which functionalized with different reagents for Cu (II) selective adsorption in aquatic ecosystems. |
