Pollution characterization, adsorption, and SERS-based detection of enrofloxacin adsorbed on microplastics in aquaculture water.

This study investigates the pollution of microplastics (MPs) in aquaculture and their adsorption of enrofloxacin (ENR), and develops a SERS detection method for ENR adsorbed on the surface of MPs based on hydrophilic membrane enrichment. Surface water samples from three South American white shrimp (Litopenaeus vannamei) ponds were analyzed for MP abundance, distribution, morphology, particle size, and type. Results revealed that MP pollution was widespread, with fibers smaller than 1 mm being predominant, and polypropylene was the main polymer type.

Bioinspired Turing-Nanoarchitected Needle for Solid Matrices Analysis: A Universal Platform Enabling Dual-Scale SERS Enhancement.

The spontaneous emergence of Turing patterns in biological systems has inspired advanced materials with superior performance, yet their untapped potential in surface-enhanced Raman spectroscopy (SERS) technology offers a transformative frontier.

The electrochemically sculpted fractal framework on silver needles serves dual roles as plasmonic amplifiers and curvature-guided templates for ZIF-8 growth, spatially aligning electromagnetic hotspots with selective-enrichment porous channels.

GPR-TSBiNet: An Information Gradient Enrichment Model for GPR B-Scan Small Target Detection.

Accurate detection of underground grounding lines remains a significant technical challenge due to their deep burial and small cross-sectional dimensions, which cause signal scattering in heterogeneous soil media. This results in blurred features in GPR B-scan images, impeding reliable target identification. To address this limitation, we propose GPR-TSBiNet, an architecture incorporating two key model innovations.

Ginger residue-derived nanocellulose as a sustainable reinforcing agent for composite films.

Nanocellulose extracted from agricultural waste for the development of reinforced sustainable composites is needed, due to a greater environmental responsibility and awareness of environmental pollution. In this work, the extraction of nanocellulose (GNC) from ginger residue was conducted via acid hydrolysis without complicated pretreatments. The potential application of GNC as a reinforcing agent for sustainable composite films was also explored.

Metal-polyphenol Multistage Competitive Coordination System for Colorimetric Monitoring Meat Freshness.

A low-cost, high-precision, and secure real-time system for monitoring food freshness can significantly improve spoilage issues, yet traditional colorimetric sensor arrays often suffer from chemical dyes' high toxicity and limited color changes. Here, a metal-polyphenol network colorimetric sensor array (MPN-CSA) is built for detecting total volatile base nitrogen (TVB-N) markers of meat freshness. The multi-level competitive coordination process between the metal-polyphenol system and amine substances endows the system with color changes far beyond those of traditional dyes (reaching a detection limit of 300 ppb).

Creating and characteristics of a novel biomacromolecules complex of pea protein isolated-tannic acid-magnesium ion.

Pea protein isolate (PPI) was used as a carrier matrix to load tannic acid (TA) due to its multiple cavity structures and reaction sites, after that, magnesium ion (M) was further added to form more stable carrier structures. PPI was covalently bound with TA to form TA-PPI complexes in alkaline conditions, then M induced the aggregation of TA-PPI to produce M-TA-PPI complexes. TA mainly interacted with free amino groups and sulfhydryl groups of PPI, thereby decreasing their content in complexes.
