“…To this end, new synthetic methodologies have been important research topics in the past two decades [ 13 ]. Consequently, several methods have been successfully established for the fabrication of spherical MIPs beads, including inverse suspension polymerization [ 20 ], emulsion polymerization [ 21 ], solution polymerization [ 22 ], multi-step swelling polymerization [ 23 ], and precipitation polymerization [ 13 , 24 ]. However, these methods are either complicated in manipulation, require a long time to complete polymerization, or require surfactants (which are difficult to remove from MIPs) to prevent aggregation of polymer particles formed in the process of polymerization.…”

Abstract:To fabricate molecularly imprinted polymer nanospheres via click reaction, five different clickable compounds were synthesized and two types of click reactions (azide-alkyne and thiol-yne) were explored. It was found that molecularly imprinted polymer nanospheres could be successfully synthesized via thiol-yne click reaction using 3,5-diethynyl-pyridine (1) as the monomer, tris(3-mercaptopropionate) (tri-thiol, 5) as the crosslinker, and hypericin as the template (MIP-NSHs). The click polymerization completed in merely 4 h to produce the desired MIP-NSHs, which were characterized by FTIR, SEM, DLS, and BET, respectively. The reaction conditions for adsorption capacity and selectivity towards hypericin were optimized, and the MIP-NSHs synthesized under the optimized conditions showed a high adsorption capacity (Q = 6.03 µmol·g −1 ) towards hypericin. The imprinting factors of MIP-NSHs towards hypericin, protohypericin, and emodin were 2.44, 2.88, and 2.10, respectively.

“…The synthesis and performance of the imprinted system is affected by the type of solvent 23 and the amount of functional monomers 24 and crosslinkers 25,26 used. In addition, the structure of ADPD may vary between keto and enol forms under conditions of altered solvent polarity, which can impact the interactions between it and the template ions.…”

“…ISP was developed as an alternative method to resolve the above‐mentioned problem. Accordingly, the small volume of the aqueous phase [ 98 ] or organic porogen [ 99 ] (oil‐in‐oil SP), containing water‐soluble functional monomers as well as template molecules, is dispersed in an immiscible organic phase containing the required amount of surface‐active agent to prevent droplet coalescence. Meanwhile, the stabilizer can act as an impurity and influences the efficiency of the formation of particles.…”

Large quantities of organic solvents and reagents are usually required in the fabrication of these materials. Moreover, the use of excess reagents in solvent extraction, purification, filtration/ centrifugation, and cleaning processes is essential for adequate product purity. Because of the numerous practical applications of advanced materials, some are synthesized on a large scale and commercialized. [3] The excessive consumption of nonrenewable, hazardous chemicals is an unsustainable practice and a prominent criticism of these materials. Nonetheless, the use of advanced materials in sensing applications, medicine, electronics, and catalysis is inevitable. [4] During various research activities, such as fabricating advanced materials, as well as in the subsequent stage, i.e., industrial operations, new challenges have arisen that impact not only almost every aspect of human life but also other living creatures and ecosystems. It is estimated that the impact of these practices will endure into the next century. [5] Since the advancement of science, industry, and technology is inevitable, scientists have been persuaded to search for methods to counteract or minimize the negative impacts of human activities. [6] Thus, green chemistry has advanced and green principles have been defined for most sciences, including synthesis, [7] analytical chemistry, [8] engineering, [9] and pharmaceutical science. [10] Fortunately, contemporary society has great awareness of deleterious environmental side effects, resulting in a sense Advances in revolutionary technologies pose new challenges for human life; in response to them, global responsibility is pushing modern technologies toward greener pathways. Molecular imprinting technology (MIT) is a multidisciplinary mimic technology simulating the specific binding principle of enzymes to substrates or antigens to antibodies; along with its rapid progress and wide applications, MIT faces the challenge of complying with green sustainable development requirements. With the identification of environmental risks associated with unsustainable MIT, a new aspect of MIT, termed green MIT, has emerged and developed. However, so far, no clear definition has been provided to appraise green MIT. Herein, the implementation process of green chemistry in MIT is demonstrated and a mnemonic device in the form of an acronym, GREENIFICATION, is proposed to present the green MIT principles. The entire greenificated imprinting process is surveyed, including element choice, polymerization implementation, energy input, imprinting strategies, waste treatment, and recovery, as well as the impacts of these processes on operator health and the environment. Moreover, assistance of upgraded instrumentation in deploying greener goals is considered. Finally, future perspectives are presented to provide a more complete picture of the greenificated MIT road map and to pave the way for further development.
