“…For environmental or biological monitoring, molecularly imprinted polymers are also actively used. For instance, a fluorescence surface imprinted sensor towards tetracycline (TC) detection was reported by Wang et al [ 8 ]. When combined with conductive fabrics, as Yinben et al reported [ 157 ], a hybrid triboelectric nanogenerator fabricated by silk fibroin and poly(vinylidene fluoride) possesses great power-density performance and electrical properties.…”

“…As well-established terminology in human intelligence and artificial intelligence [ 6 , 7 ], it is the intellectual power that gives human cognitive capabilities along with self-awareness to reason and understand, think and resolve, innovate and design, plan and predict, communicate and interact with each other. In a word, human intelligence can be seen as the ability to define, solve and learn from problems in various scenarios [ 8 , 9 , 10 ]. Similarly, from the deduction of parallel interpretation, the “intelligence” of a material could be considered to be the capability of property changes responsive to environmental stimuli with corresponding molecular-level structural rearrangement [ 11 , 12 , 13 ].…”

Intelligent materials, also known as smart materials, are capable of reacting to various external stimuli or environmental changes by rearranging their structure at a molecular level and adapting functionality accordingly. The initial concept of the intelligence of a material originated from the natural biological system, following the sensing–reacting–learning mechanism. The dynamic and adaptive nature, along with the immediate responsiveness, of the polymer- and fiber-based smart materials have increased their global demand in both academia and industry. In this manuscript, the most recent progress in smart materials with various features is reviewed with a focus on their applications in diverse fields. Moreover, their performance and working mechanisms, based on different physical, chemical and biological stimuli, such as temperature, electric and magnetic field, deformation, pH and enzymes, are summarized. Finally, the study is concluded by highlighting the existing challenges and future opportunities in the field of intelligent materials.

“…Using allyl fluorescein as the fluorescent functional monomer, Wang et al [93] prepared FIPs with specific response to tetracycline using the surface imprinting method and applied them to the fluorescence analysis of tetracycline in human serum and pig urine. Using malachite green as the template molecule, (3-Aminopropyl)triethoxysilane (APTES)as the functional monomer, and tetraethoxysilane (TEOS) as the crosslinking agent, Wu et al [94] prepared a MIFs for specific recognition of malachite green by embedding CdTe QDs.…”

Molecular imprinting technology (MIT), also known as molecular template technology, is a new technology involving material chemistry, polymer chemistry, biochemistry, and other multi-disciplinary approaches. This technology is used to realize the unique recognition ability of three-dimensional crosslinked polymers, called the molecularly imprinted polymers (MIPs). MIPs demonstrate a wide range of applicability, good plasticity, stability, and high selectivity, and their internal recognition sites can be selectively combined with template molecules to achieve selective recognition. A molecularly imprinted fluorescence sensor (MIFs) incorporates fluorescent materials (fluorescein or fluorescent nanoparticles) into a molecularly imprinted polymer synthesis system and transforms the binding sites between target molecules and molecularly imprinted materials into readable fluorescence signals. This sensor demonstrates the advantages of high sensitivity and selectivity of fluorescence detection. Molecularly imprinted materials demonstrate considerable research significance and broad application prospects. They are a research hotspot in the field of food and environment safety sensing analysis. In this study, the progress in the construction and application of MIFs was reviewed with emphasis on the preparation principle, detection methods, and molecular recognition mechanism. The applications of MIFs in food and environment safety detection in recent years were summarized, and the research trends and development prospects of MIFs were discussed.

“…Tetracycline hydrochloride (Figure 1) is one of the most common broad-spectrum tetracycline-based antibiotics, which is widely used for treating bacterial infections and as a feed additive in a variety of animal husbandry and aquacultures, due to its advantages such as its low cost, obvious effects, low toxicity and wide antimicrobial spectrum [1,2]. However, the abuse of antibiotics has become a major global issue since it causes serious environmental and food safety issues, due to their persistence and biological accumulation, and this abuse poses a latent threat to human health [3,4].…”

Serious environmental and human health problems caused by the abuse of antibiotics have attracted worldwide concern. Recently, metal–organic frameworks (MOFs) with high porosity have drawn wide attention for their effects in the adsorption and removal of pollutants from complex matrices. Herein, a high-stable metal organic framework (MOF), i.e., ((ZnCl2)3(L)2·DMF)n, where L=1,3,5-tris((pyridin-4-ylthio)methyl)benzene), MOF 1, was applied to adsorb and remove tetracycline from sewage and dairy products. The results showed that MOF 1 exhibited a strong performance in the adsorption of tetracycline. The effects of initial pH values, adsorbent dose, contact time and ionic strength of the adsorption performance of MOF 1 were investigated. The adsorption kinetics best fit the pseudo-second order model, and the adsorption isotherms matched the Langmuir adsorption model well. It was indicated that both chemical adsorption and physical adsorption play an important role in the adsorption process, and the adsorption of tetracycline was homogeneous and occurred on a monolayer on the surface of MOF 1. Additionally, the stability of MOF 1 and the details of the adsorption mechanism were also investigated. Thus, this study provides a new candidate for the application of MOFs-based adsorbents in the removal of antibiotics from sewage and dairy products.
