AI Article Synopsis

  • This study focused on creating a patch made of cellulose/β-cyclodextrin that can noninvasively monitor glucose levels in interstitial fluid using a technique called reverse iontophoresis.
  • The sensor demonstrated excellent performance with a high diffusion coefficient, strong linear correlation, and a sensitivity that remained unaffected by common interfering substances at physiological levels.
  • The findings suggest that this innovative epidermal sensing approach could be a promising tool for continuous glucose monitoring in diabetes management.

Article Abstract

In this study, we aimed to develop a cellulose/β-cyclodextrin (β-CD) electrospun immobilized GOx enzyme patch with reverse iontophoresis for noninvasive monitoring of interstitial fluid (ISF) glucose levels (0.1-0.6 mM dm). analysis, performed using a sensor attached to flexible substrates, revealed that the high diffusion coefficient (9.0 × 10 cm s), the linear correlation coefficient ( = 0.998), the detection limit (9.35 × 10 M), and the linear range sensitivity (0-1 mM) of the sensor (5.08 μA mM) remained unaffected by the presence of interfering substances (, fructose, sucrose, uric acid, and acetaminophen) at physiological levels. The present results indicate that the new epidermal sensing strategy using nanofibers for continuous glucose monitoring has potential to be applied in diagnosis of diabetes.

Hydrogel-based sensors have been widely studied for perceiving the environment. However, the simplest type of resistive sensors still lacks sensitivity to localized strain and other extractable data. Enhancing their sensitivity and expanding their functionality to perceive multiple stimuli simultaneously are highly beneficial yet require optimal material design and proper testing methods.

In this study, cellulose nanofibers (CNFs) were utilized as a synergistic agent, and combined with phytic acid arginine salt (PaArg) via blending and bonding. The effects of these different binding techniques of CNFs and PaArg on the flame retardant and mechanical properties of poly (butylene succinate) (PBS) were explored. The results indicated that both blended and bonded CNFs and PaArg enabled PBS composites to achieve a UL 94 V-0 rating, with the limiting oxygen index (LOI) value of the composite exceeding 28 %.

The development of an efficient coating with comprehensive antimicrobial and anticorrosion properties for metals is crucial. The present study used a one-pot strategy to fabricate a high-performance nanocomposite coating of carboxylated nitrile butadiene rubber/cellulose nanofibers/zinc oxide (XNBR/CNF-ZnO), demonstrating excellent potential for application in the protection against metal corrosion. Eco-friendly CNF-ZnO nanomaterials, prepared using the in-situ generation method, were used as reinforcing fillers, while XNBR was used as the matrix material.

The uncontrolled dendrite growth and detrimental parasitic reactions of Zn anodes currently impede the large-scale implementation of aqueous zinc ion batteries. Here, we design a versatile quasi-solid-state polymer electrolyte with highly selective ion transport channels via molecular crosslinking of sodium polyacrylate, lithium magnesium silicate and cellulose nanofiber. The abundant negatively charged ionic channels modulate Zn desolvation process and facilitate ion transport.

Water purification has always been a critical yet challenging issue. In this study, an organic-inorganic composite membrane was developed using 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized bacterial cellulose (BC) nanofibers and hydroxyapatite nanowires (HAPNW) with tunable wettability for advanced membrane separation applications. The resulting free-standing TEMPO-BC/HAPNW filter membrane exhibited strong mechanical strength, high flexibility, exceptional deformability, and a high pure water flux of up to 800 L·m·h due to its porous architecture and inherent hydrophilicity.
