A Novel Drug‐Loaded Porous Parylene Electrode for Targeted Anti‐Inflammatory Therapy and Hearing Preservation in Cochlear Implantation

Advanced Healthcare Materials, EarlyView.
A porous parylene‐coated electrode loaded with dexamethasone was developed to reduce inflammation after cochlear implantation. In guinea pigs, the device provided sustained drug release, maintained biocompatibility, improved auditory brainstem response thresholds, and reduced inflammatory cell infiltration and TNF‐α expression.

Solvent effect on carboxymethylation of cellulose [PDF]

Journal of Applied Polymer Science, 1993
The relationship between the composition of the solvent (water/isopropyl alcohol) and the degree of substitution, viscosity and molecular weight of carboxymethylcellulose (CMC) is investigated. It is found that the alcohol facilitates the destruction of cellulose crystalline structure and the diffusion of the small reagent molecules into the cellulose,

Carboxymethyl Cellulose as a Food Emulsifier: Are Its Days Numbered?

Polymers, 2023
Carboxymethyl cellulose use in industry is ubiquitous. Though it is recognized as safe by the EFSA and FDA, newer works have raised concerns related to its safety, as in vivo studies showed evidence of gut dysbiosis associated with CMC’s presence. Herein lies the question, is CMC a gut pro-inflammatory compound?

Operation Limits of Integrated Photo‐Rechargeable Batteries

Advanced Materials, EarlyView.
This study elucidates the operational limitations of integrated photo‐rechargeable batteries. We demonstrate that the photo‐charging process is fundamentally restricted not only by material‐to‐material energy level alignment but also by transient capacitive charge accumulation within the cathode framework.

Modulating superabsorbent polymer properties by adjusting the amphiphilicity

Frontiers in Chemistry, 2022
The role of amphiphilicity in polysaccharide-based superabsorbent polymers is paramount in determining material properties. While the performance of freeze-dried polymers is improved by maximizing hydrophilicity, this may not be the case for evaporative ...
