Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

Advanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

Enhancing Metabolomics Analysis: Performance Evaluation of OPLS‐DA and OPLS‐EP Models

Journal of Chemometrics
ABSTRACT In the analysis of metabolomics data, selecting the appropriate statistical approach is crucial for maximizing model interpretation, predictivity and reliability. This study evaluates the effectiveness of Orthogonal Partial Least Squares (OPLS) models, specifically comparing OPLS‐DA (assuming sample independence) and OPLS‐EP (

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

Advanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Targeted Metabolomics Combined with OPLS-DA to Elucidate Phenolic Differences in Eight Cashew Apples

Agriculture
Phenolic compounds were separated and identified using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) and analyzed with OPLS-DA and metabolomics in eight cashew apples. The results showed that the phenolic compound content in Bra4 was the highest, while Gua had the lowest levels. The content of 39 phenolic compounds (nine types)
