Biomimetic Strategy to Enhance Epithelial Cell Viability and Spreading on PEEK Implants
( American Chemical Society , 2022 , Article)Polyetheretherketone (PEEK) is a biocompatible material widely used in spinal and craniofacial implants, with potential use in percutaneous implants. However, its inertness prevents it from forming a tight seal with the ... -
Chiral Tartaric Acid Improves Fracture Toughness of Bioactive Brushite-Collagen Bone Cements
( American Chemical Society , 2020 , Article)Brushite cements are promising bone regeneration materials with limited biological and mechanical properties. Here, we engineer a mechanically improved brushite-collagen type I cement with enhanced biological properties ... -
Disclosing Agent for Resin Composite Based on Adsorption Surface Treatment
( American Chemical Society , 2021 , Article)A composite disclosing agent can help dentists distinguish resin boundaries from the tooth structure and facilitate its complete removal while avoiding damage to the surrounding sound tooth structures. In this study we ... -
Selective Crystal Growth Regulation by Chiral α-Hydroxycarboxylic Acids Improves the Strength and Toughness of Calcium Sulfate Cements
( American Chemical Society , 2020 , Article)Natural biominerals, such as bones and teeth, use acidic matrix biomolecules to control growth, morphology, and organization of the brittle hydroxyapatite crystals. This interplay provides biominerals with outstanding ... -
The Role of Surface Chemistry in the Osseointegration of PEEK Implants
( American Chemical Society , 2022 , Article)Poly(etheretherketone) (PEEK) implants suffer from poor osseointegration because of chronic inflammation. In this study, we hypothesized that adding NH2and COOH groups to the surface of PEEK could modulate macrophage ... -
Titanium-Containing Silicate-Based Sol-Gel Bioactive Glass: Development, Characterization, and Applications
( American Chemical Society , 2021 , Article)Bioactive glasses are surface-reactive glasses that, when placed in physiological fluid, undergo a transformation from glass to hydroxyapatite. Doping the bioactive glass with metallic ions can impart desirable and unique ...
