“…This method begins with a homogenous system that becomes heterogeneous in the continuous phase. Initially, all components are completely soluble, but the polymer becomes insoluble and precipitates during initiation [28][29][30][31][32]. The interaction of andrographolide with MAA is depicted in Figure 2, while the scheme of reaction is shown in Figure 3.…”

Molecularly Imprinted Polymer (MIP) has a specific cavity in which the conformity of shape, size, and functionalities corresponds with its template molecule and has been widely used in separation processes. Therefore, this study aims to examine the application of MIP for the purification of andrographolide. The MIP was synthesized by precipitation polymerization using methacrylic acid (MAA) and ethylene glycol dimethacrylate (EGDMA) as the functional monomer and cross-linker, andrographolide as a template, and acetonitrile:toluene (3:1) as porogen solvent. The results showed that the binding capacity of Synthesized MIP was 1.2486 mg/g, while the particle size was 295.5 nm with a polydispersity index of 0.064. Furthermore, the imprinting and selectivity factors were 1.148 and 12.37, respectively. The purification process by MIP increased the purity from 55.37 ± 0.69 to 94.94% ± 0.34, while the isolate characterization showed that purified andrographolide had a similar character compared to the standard.

“…It can overcome the disadvantages of low binding capacity and difficulty in elution of traditional MIPs. Core-shell structured MIPs are the major type of surface imprinting MIPs, owing to the increased surface area and larger binding capacity, and thus, they are widely used for detecting antibiotic residues (Ji et al, 2018;Liu et al, 2018;Negarian et al, 2019;Qin et al, 2019;Zhu et al, 2019a).…”

“…Moreover, the nanostructured MIPs can be directly used without grinding, simplifying the experimental operation. The commonly used methods to synthesize nano-MIPs microspheres include precipitation polymerization (Liu et al, 2018), sol-gel (Li G. et al, 2018;Diaz-Alvarez et al, 2019), and core-shell polymerization (Qin et al, 2019). Nanoimprinting technology can be divided into zero-dimensional, one-dimensional, and two-dimensional types (Li and Wang, 2020).…”

Abuse and residues of antibiotics cause great harm to organisms and the environment. Appropriate sample pretreatment is usually required for sensitive determination, because of the low content presence of a variety of antibiotics in complicated matrices. Molecular-imprinting-based solid-phase extraction (MISPE) has been widely used for sample pretreatment of antibiotics, using molecularly imprinted polymers (MIPs) as adsorbents. Herein, we comprehensively review the recent advances of MISPE of antibiotics, followed by chromatographic analysis. Various solid-phase extraction (SPE) modes based on MIPs are briefly introduced, such as conventional SPE, dispersive SPE, magnetic SPE, matrix solid-phase dispersion, and pipette-tip SPE. Then, several emerging preparation techniques for antibiotics MIPs are summarized including surface imprinting, nanoimprinting, living/controlled radical polymerization, multitemplate imprinting, multifunctional monomer imprinting, and dummy template imprinting. Subsequently, applications of MISPE to analysis of a variety of antibiotics residues since 2018 are overviewed, including sulfonamides, quinolones, tetracycline, and others. Finally, the preparation and application of antibiotics MIPs are prospected.
