Article Abstract
In this test, the eggshell membrane (ESM) is selected as the support membrane for the biocompatibility and anchors CNTs on the surface to increase the mechanical properties. Then Ag NPs are decorated on CNTs-ESM substrate as SERS substrate by twice in-situ reduction. Finally, a layer of imprinted polymers is coated on the surface of the substrate to synthesize the imprinted membrane for selective detection of spiramycin. It is exhibited from the characteristic results that the CNTs significantly increase the mechanical properties and the detection sensitivity, simultaneously. When the concentration of SP changes between 10 ∼ 10 M, there is a linear relationship between SERS intensity and SP concentration. The detection limit is 10 M, and the correlation coefficient R is 0.9864. The SERS imprinted membrane can be applied into the detection of antibiotics in practical sample, which broadens the research field of antibiotics detection.

Osteopontin (OPN), a multifunctional milk protein essential for bioactive functions, remains challenging to isolate efficiently due to the limited specificity of conventional methods. We developed hydrogel-based molecularly imprinted membranes (MIMs) for selective OPN recognition. Dimethylaminopropyl methacrylamide (DMAPMA) and N-isopropylacrylamide (NIPAM) were selected as functional monomers based on molecular docking and molecular dynamics (MD) simulations, ensuring optimized binding interactions.

The quest to develop energy-efficient and fast optoelectronic control of memory devices is essential. In this respect, ferroelectric materials are gaining tremendous importance in information and communication technology. Here, we demonstrate light-controlled polarisation switching on a subsecond timescale ( <500 ms) in a freestanding BaTiO membrane, which is nearly 1200 times faster than the previously reported response using a BaTiO thin film.

This study presents the first application of a graphene/cobalt hexacyanoferrate composite as an ion-to-electron transducer interlayer for the selective electrochemical determination of bupropion. The composite was prepared by homogeneously dispersing graphene with tween 80 and then decorating it with cobalt-hexacyanoferrate nanoparticles. Modifying glassy carbon electrodes with this interlayer improved and stabilized the measured potential by preventing the formation of an aqueous layer beneath the sensing membrane and enhancing charge transfer.

Virus sensing and removal are critical for public health, particularly in preventing the spread of infectious diseases and ensuring safe water, air, and clinical environments. Current virus detection tools utilize recognition elements suffering from high cost, low stability, and specificity, and time-consuming production methods. Meanwhile, conventional virus removal techniques are often hindered by inefficiency, complexity, and the potential for harmful byproducts.

When subjected to an alternating current (AC) electric field, the frequency of the field introduces an extra degree of control over electrokinetic phenomena, as well as molecular alignment and structural conformation that facilitate the binding of adsorbate onto the recognition sites to enhance the performance of adsorption. Herein, Nylon-6 fibrous membrane were coated with a CO2-philic layer of molecularly imprinted polyethyleneimines (MIP) for CO capture using coaxial electrospinning. The MIP-coated Nylon6 fibrous membrane (6/MIP) was place in a electric polarization (EP) device consisting of two mesh electrodes.
