Surface functionalization of 3D glass–ceramic porous scaffolds for enhanced mineralization in vitro

[Article] SURFACE FUNCTIONALIZATION OF 3D GLASS-CERAMIC POROUS SCAFFOLDS FOR ENHANCED MINERALIZATION IN VITRO

Surface modification of interconnected porous scaffolds.

Surface properties of scaffolds play an important role in cell adhesion and growth. Biodegradable poly(alpha-hydroxy acids) have been widely used as scaffolding materials for tissue engineering; however, the lack of functional groups is a limitation. In this work, gelatin was successfully immobilized onto the surface of poly(alpha-hydroxy acids) films and porous scaffolds by a new entrapment pr...

Nanostructured Porous Silicon Scaffolds for Enhanced Biocompatibility of Multichannel Microelectrodes

Nanostructured Porous Silicon Scaffolds for Enhanced Biocompatibility of Multichannel Microelectrodes Stefanie Joy Hallman Karen Moxon, Ph.D. Many different types of microelectrodes have been developed for use as a direct Brain-Machine Interface (BMI) to chronically record singleneuron action potentials from ensembles of neurons and control an effector. For example, a BMI device designed for hu...

Plasma-induced polymerization as a tool for surface functionalization of polymer scaffolds for bone tissue engineering: an in vitro study.

A commonly applied strategy in the field of tissue engineering (TE) is the use of temporary three-dimensional scaffolds for supporting and guiding tissue formation in various in vitro strategies and in vivo regeneration approaches. The interactions of these scaffolds with highly sensitive bioentities such as living cells and tissues primarily occur through the material surface. Hence, surface c...

Microstructure, in Vitro Corrosion and Mechanical Properties of porous Magnesium-Zinc Nanocomposite Scaffolds

Due to good biocompatibility, corrosion and mechanical properties, magnesium (Mg) is considered promising degradable material for orthopedic applications. In this work, Mg-MgZnx (x= 1, 2, 3 and 4) nanocomposites scaffolds with different porosities were synthesized via powder metallurgy method. The microstructure, composition, in vitro corrosion and mechanical properties of porous magnesium-zinc...
