AB  - In this study, a colorimetric sensor was developed for the detection of 
      organophosphorus pesticides (OPs) using a heterogeneous nanozyme with 
      phosphatase-like activity. Herein, this heterogeneous nanozyme (Au-pCeO(2)) was 
      obtained by the modification of gold nanoparticles on porous cerium oxide 
      nanorods, resulting in synergistic hydrolysis performance for OPs. Taking methyl 
      parathion (MP) as the target pesticide, the catalytic performance and mechanism 
      of Au-pCeO(2) were investigated. Based on the phosphatase-like Au-pCeO(2), a 
      dual-mode colorimetric sensor for MP was put forward by the analysis of the 
      hydrolysis product via a UV-visible spectrophotometer and a smartphone. Under 
      optimum conditions, this dual-mode strategy can be used for the on-site analysis 
      of MP with concentrations of 5 to 200 muM. Additionally, it can be applied for MP 
      detection in pear and lettuce samples with recoveries ranging from 85.27% to 
      115.87% and relative standard deviations (RSDs) not exceeding 6.20%, which can 
      provide a simple and convenient method for OP detection in agricultural products.
