Photoresponsive hollow molecularly imprinted polymer for trace triamterene in biological samples

Designing and controlling the morphology of spherical molecularly imprinted polymers

“…In this method, the step of removing cores is added on the basis of preparing core-shell MIPs, and selective etching is used to remove cores. Usually, PS, 158,159 SiO 2 , [160][161][162][163][164][165][166][167][168][169] mesoporous silica, [170][171][172][173] 174 CaCO 3 175 and Fe 3 O 4 @ SiO 2 [176][177][178][179] are used as the sacrificial material to prepare H-MIPs. This method is widely used because both organic and inorganic H-MIPs can be prepared.…”

“…22,23 Stimuli-responsive MIPs are easily obtained by using stimuli-responsive functional monomers. [24][25][26][27][28][29][30][31] Photoresponsive MIPs that are prepared by using photo-responsive azobenzene derivatives as the functional monomers have been used to determine trace pesticide residue in fruits and vegetables, 32 phthalate esters in plastics, 33 bisphenol A in water, 34,35 uric acid in physiological uids, 36 triamterene in human urine and serum, 37 4-ethylphenol in red wine, 38 and illegal additives (melamine) and antibiotics (griseofulvin) in milk. 30,39 Those photo-responsive MIPs are generally prepared by free radical polymerization between the azobenzene functional monomers and crosslinkers.…”

Selective enrichment‐release of trace dibutyl phthalate via molecular‐imprinting based photo‐controlled switching followed by high‐performance liquid chromatography analysis

“…Stimulus response polymers can change their physicochemical properties under stimulus from the external environment [15][16][17][18][19]. In the preparation process of molecularly imprinted polymers, responsive functional monomers are introduced to make it have the properties in pH, temperature, optical, and magnetic response [20][21][22][23][24][25]. The monomers commonly used in photo-response molecular imprinting are azobenzene and its derivatives, which are mainly composed of photo-response chromophobe group, recognition group and polymerization group [26].…”

“…Moreover, the geometrical structure and dipole moment of azobenzene and its derivatives change greatly during photoisomerization [20]. Because of their rapid and reversible photoisomerization, photo-response molecular imprinting of azobenzene has been widely used in drug release and uptake, food pollutants and catalysis [21]. Based on this functional monomer 4-[(4-methacryloyloxy) phenylazo] benzenesulfonic acid (MAPASA), previous studies have developed water-soluble functional monomers containing azobenzene and demonstrated the potential of stimulating response to molecularly imprinted polymers [22].…”
