Monodisperse, molecularly imprinted polymers for creatinine by modified precipitation polymerization and their applications to creatinine assays for human serum and urine

Molecularly imprinted polymer for chlorogenic acid by modified precipitation polymerization and its application to extraction of chlorogenic acid from Eucommia ulmodies leaves

“…MIPs for CGA and non-imprinted polymers (NIPs) were prepared by a modified precipitation polymerization method as previously reported [20,21], as shown in Table 1. Briefly, CGA (1.5 mmol) dissolved in 1.0 and 0.5 mL of methanol (MeOH) and 1.0 mL of dimethylsulfoxide (DMSO), respectively, as a template molecule, MAA (6 mmol) as a functional monomer, DVB (28.8 mmol) as a crosslinker and AIBN (1.9 mmol) as an initiator were added in 128 mL of acetonitrile-toluene (3/1, v/v).…”

“…Previously, we prepared a monodisperse MIP for creatinine by modified precipitation polymerization [20,21]: creatinine was first dissolved in a small portion of water, and then a MIP for creatinine was prepared by precipitation polymerization. Three MIPs for CGA, which is hydrophilic, were prepared using MeOH or DMSO as a co-solvent for dissolving a template molecule, CGA, by modified precipitation polymerization.…”

“…Recently, we prepared a monodisperse MIP for creatinine by modified precipitation polymerization [20,21]. Because creatinine is hydrophilic, it does not dissolve in porogenic solvents.…”

“…The use of water to dissolve creatinine distinguished this method from other precipitation polymerizations. The method was called modified precipitation polymerization [20,21]. CGA did not dissolve in porogenic solvent, a mixture of acetonitrile and toluene.…”

Preparation of bio‐based keratin‐derived magnetic molecularly imprinted polymer nanoparticles for the facile and selective separation of bisphenol A from water

“…The mixture was sonicated and degassed with nitrogen for 10 min to eliminate the oxygen. The polymerization was allowed to proceed in a water‐bath at 60°C for 24 h. The prepared MMIP was collected by applying an external magnet, washed with ethanol three times, and dried in vacuum oven at 50°C . Mixture of 5% acetic acid/methanol solution was used to remove the BPA molecules existing in MMIP.…”
