AB  - Based on our developed sodium hyaluronate-functionalized urea-formaldehyde 
      (HA-UF) monolith, a silver nanoparticles-coated monolithic column has been 
      fabricated via the interaction between silver nanoparticles (Ag NPs) and HA. The 
      successful coating of Ag NPs on the parent monolith was proven by SEM, EDAX, 
      UV-vis spectrum and XPS. Nitrogen adsorption desorption isotherms and 
      Barret-Joyner-Halenda (BJH) pore size distributions of the parent and resultant 
      monolith were also performed. Due to the Ag(+)-like affinity interaction caused 
      by the contact of unsaturated compounds and Ag NPs, the Ag NPs-coated monolith 
      showed satisfactory extraction efficiency towards these compounds, and was 
      applied for in-tube solid-phase microextraction (SPME) of monounsaturated fatty 
      acid methyl esters (MUFAMEs). Several factors for in-tube SPME, such as ACN 
      percentage in the sampling solution, elution volume, sampling and elution flow 
      rate, were investigated with respect to the extraction efficiency of model 
      MUFAMEs. Under the optimized SPME conditions, a simple in tube SPME-Ag(+)-HPLC 
      method for detection of model MUFAMEs has been proposed, the limits of detection 
      (LODs) were less than 5.2 mug/kg, and the recoveries of spiked French fry samples 
      were ranged from 86.6% to 96.1% with relative standard deviations (RSDs) less 
      than 5.2%. This study provided an Ag NPs-coated monolith with good 
      reproducibility and repeatable extraction performance, and developed an efficient 
      method for in-tube SPME of MUFAMEs in practical food samples.
