Expanding the Scope of an Amphoteric Condensed Tannin, Tanfloc, for Antibacterial Coatings [PDF]

Journal of Functional Biomaterials, 2023
Bacterial infections are a common mode of failure for medical implants. This study aims to develop antibacterial polyelectrolyte multilayer (PEM) coatings that contain a plant-derived condensed tannin polymer (Tanfloc, TAN) with inherent antimicrobial ...

Tanfloc/heparin polyelectrolyte multilayers improve osteogenic differentiation of adipose-derived stem cells on titania nanotube surfaces. [PDF]

Carbohydr Polym, 2021
In this study, a surface modification strategy using natural biopolymers on titanium is proposed to improve bone healing and promote rapid and successful osseointegration of orthopedic implants. Titania nanotubes were fabricated via an anodization process and the surfaces were further modified with polyelectrolyte multilayers (PEMs) based on Tanfloc (a

Tanfloc-Modified Titanium Surfaces: Optimizing Blood Coagulant Activity and Stem Cell Compatibility. [PDF]

ACS Biomater Sci Eng
This study explores the synergistic effects of combining titania nanotubes (TiNTs) with the biopolymer Tanfloc (TAN) to enhance the surface properties of TiNTs for biomedical applications. We investigated the interactions of blood components and human adipose-derived stem cells (ADSCs) with TiNT surfaces covalently functionalized with Tanfloc (TAN), an

Enhanced hemocompatibility and antibacterial activity on titania nanotubes with tanfloc/heparin polyelectrolyte multilayers. [PDF]

J Biomed Mater Res A, 2020
AbstractBiomaterial‐associated thrombus formation and bacterial infection remain major challenges for blood‐contacting devices. For decades, titanium‐based implants have been largely used for different medical applications. However, titanium can neither suppress blood coagulation, nor prevent bacterial infections.

Landfill Leachate and Coagulants Addition Effects on Membrane Bioreactor Mixed Liquor: Filterability, Fouling, and Pollutant Removal [PDF]

Membranes
Urban wastewater (UWW) and landfill leachate (LL) co-treatment using membrane bioreactors (MBRs) is a valuable method for managing LL in cities. Coagulants can enhance the filterability of mixed liquor (ML), but the assessment of fouling is still needed.
