Langmuir Monolayer Studies of Phosphatidylcholine Membranes with Naproxen on the Polysaccharide Subphase

open access: yesMolecules
Natural polysaccharides are biocompatible and biodegradable; therefore, they can be widely used in drug delivery, tissue engineering and wound healing. In this context, the interactions between polysaccharides, drugs and biological membranes are of great

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

open access: yesBMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Triptycene‐Based Tripodal Molecular Platforms: A Comparative Study of Photoswitchable Langmuir–Blodgett Films on Metallic and Nonmetallic Surfaces

open access: yesChemistry – A European Journal, EarlyView.
A modular triptycene‐based platform enables the preparation of Langmuir–Blodgett monolayers of structurally diverse molecular photoswitches on quartz and gold. Surface‐sensitive characterization and optical spectroscopy demonstrate that the intrinsic switching behavior is retained after surface immobilization. ABSTRACT Photoswitchable molecular systems
