Published: June 23, 2022

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.

Chiral molecular imprinting-based SERS detection strategy for absolute enantiomeric discrimination

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Sept. 30, 2022

Abstract Chiral discrimination is critical in environmental and life sciences. However, an ideal chiral strategy has not yet been developed because of the inevitable nonspecific binding entity wrong enantiomers or insufficient intrinsic optical activities molecules. Here, we propose “inspector” recognition mechanism (IRM), which implemented on a imprinted polydopamine (PDA) layer coated surface-enhanced Raman scattering (SERS) tag layer. The IRM works based permeability change PDA after scrutiny by inspector molecule. Good enantiomer can specifically recognize fully fill cavities, whereas cannot. Then linear shape aminothiol molecule, as status introduced, only percolate through vacant nonspecifically occupied inducing SERS signal to decrease. Accordingly, chirality information exclusively stems from good specific binding, while curbed. benefits sensitivity versatility, enabling absolute wide variety molecules regardless size, functional groups, polarities, activities, scattering, number centers.

Published: May 5, 2022

Combating environmental pollution constantly requires new affinity tools to selectively recognize and sensitively detect them. Molecularly imprinted polymers (MIPs) are plastic antibodies that have exhibited great potential as recognition units in optical sensing platforms monitor wide varieties of pollutants, including ionic species, organic compounds, gases, even manufactured nanoparticles. The construction, strategies, applications molecular-imprinting-based sensors (MI-OSs) been discussed recent reviews, thus we deliberately set them aside. This Perspective elaborates on unanswered questions main approaches being taken address the challenges MI-OS technologies, which less considered until now. Specifically, highlight obscure technical aspects fabrication validation impact their practical importantly offer conceivable solutions related problems bridge research gap.

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

Analytical Chemistry, Journal Year: 2024, Volume and Issue: 96(16), P. 6417 - 6425

Published: April 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
