Constraining the Teratogenicity of Pesticide Pollution by a Synthetic Nanoreceptor.

The teratogenicity of the pesticide nereistoxin (NTX) and its derivative thiocyclam (THI) towards aquatic life was dramatically constrained by a synthetic nanoreceptor, cucurbit[7]uril, through selective encapsulation of the pesticides (K of 3.24(±0.31)×10  m and K of 7.46(±0.10)×10  m ), as evidenced by the rate of hatchability, morphology development, and tyrosinase activity of zebrafish larvae incubated with the pesticides (3-300 μm) in the absence and in the presence of 300 μm cucurbit[7]uril, demonstrating the significant potential of the nanoreceptor in managing ecological pollution of these pesticides.
