Abstract Molecular imprinting technology (MIT) produces artificial binding sites with precise complementarity to substrates and thereby is capable of exquisite molecular recognition. Over five decades evolution, it predicted that the resulting host imprinted materials will overtake natural receptors for research application purposes, but in practice, this has not yet been realized due unsustainability their life cycles (i.e., precursors, creation, use, recycling, end‐of‐life). To address issue, greenificated molecularly polymers (GMIPs) are a new class plastic antibodies have approached sustainability by following one or more greenification principles, while also demonstrating far‐reaching applications compared counterparts. In review, most recent developments delicate design advanced GMIPs six fast‐growing emerging fields surveyed, namely biomedicine/therapy, catalysis, energy harvesting/storage, nanoparticle detection, gas sensing/adsorption, environmental remediation. addition, distinct features highlighted, optimal means utilize these attaining incredibly discussed. Importantly, obscure technical challenges MIT revealed, conceivable solutions offered. Lastly, several perspectives on future directions proposed.

The abuse and residues of antibiotics have a great impact on the environment organisms, their determination has become very important. Due to low contents, varieties complex matrices, effective recognition, separation enrichment are usually required prior determination. Molecularly imprinted polymers (MIPs), kind highly selective polymer prepared via molecular imprinting technology (MIT), used widely in analytical detection antibiotics, as adsorbents solid-phase extraction (SPE) recognition elements sensors. Herein, recent advances MIPs for antibiotic residue analysis reviewed. Firstly, several new preparation techniques detecting briefly introduced, including surface imprinting, nanoimprinting, living/controlled radical polymerization, multi-template multi-functional monomer dummy template imprinting. Secondly, SPE modes based summarized, namely packed SPE, magnetic dispersive matrix extraction, microextraction, stir-bar sorptive pipette-tip SPE. Thirdly, basic principles MIP-based sensors three sensing modes, electrochemical sensing, optical mass also outlined. Fourthly, research progress molecularly SPEs (MISPEs) electrochemical/optical/mass various environmental food samples since 2018 comprehensively reviewed, sulfonamides, quinolones, β-lactams so on. Finally, application prospects

Molecular Imprinting-Based SERS Detection Strategy for the Large-Size Protein Quantitation and Curbing Non-Specific Recognition

Analytical Chemistry, Год журнала: 2024, Номер 96(16), С. 6417 - 6425

Опубликована: Апрель 12, 2024

Molecular imprinting-based surface-enhanced Raman scattering (MI-SERS) sensors have shown remarkable potential from an academic standpoint. However, their practical applications, especially in the detection of large-size protein (≥10 nm), face challenges due to lack versatile sensing strategies and nonspecific fouling matrix species. Herein, we propose a reporter inspector mechanism (RRIM) implemented on protein-imprinted polydopamine (PDA) layer coated SERS active substrate. In RRIM, after recognition, permeability PDA imprinted cavities undergoes changes that are scrutinized by molecules. Target proteins can specifically bind fully occupy cavities, whereas species cannot. Then, molecules with suitable size introduced serve as both inspectors recognition status inducers signal, which only penetrate through vacant nonspecifically filled cavities. Consequently, signal exclusively originate specific binding target proteins, while is curbed. The RRIM enables reproducible quantitation cyanobacteria-specific model phycocyanin, at level down 2.6 × 10
