Brilliant Green Decorated Graphene Oxide for the Detection of Cucurbit[7]uril

Abstract

Among the synthetic receptors, Cucurbiturils have gained much attention recent days due to their unique binding potential with variety of drugs and dyes. However, no facile detection method using UV-vis spectroscopy has been developed. Here, we have developed the brilliant green decorated graphene oxide (BGGO) for the detection of cucurbit[7]uril (CB[7]) with good selectivity and sensitivity. Thus, BGGO could able to detect the CB[7] and turn on the release of brilliant green quantitatively. Among the sensors for CB[7], BGGO is the low-cost and sensitive sensor for CB[7] with high selectivity
