TI  - Selective Recognition of Gallic Acid Using Hollow Magnetic Molecularly Imprinted 
      Polymers with Double Imprinting Surfaces.

AB  - Gallic acid is widely used in the field of food and medicine due to its 
      diversified bioactivities. The extraction method with higher specificity and 
      efficiency is the key to separate and purify gallic acid from complex biological 
      matrix. Herein, using self-made core-shell magnetic molecularly imprinted 
      polymers (MMIP) with gallic acid as template, a hollow magnetic molecularly 
      imprinted polymer (HMMIP) with double imprinting/adsorption surfaces was prepared 
      by etching the mesoporous silica intermediate layer of MMIP. The characterization 
      and adsorption research showed that the HMMIP had larger specific surface area, 
      higher magnetic response strength and a more stable structure, and the 
      selectivity and saturated adsorption capacity (2.815 mmol/g at 318 K) of gallic 
      acid on HMMIP were better than those of MMIP. Thus, in addition to MMIP, the 
      improved HMMIP had excellent separation and purification ability to selectively 
      extract gallic acid from complex matrix with higher specificity and efficiency.
