Surface Passivated Nanocarbon Generates a Phase-Separated Hydrogel Meshwork for Skeletal Muscle Tissue Engineering

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Tissue Engineering

Background:

• Controlling polymeric network orientation is crucial for advanced hydrogel-based tissue engineering.
• Existing methods often rely on extracellular salts, which can have limitations.

Purpose of the Study:

• To investigate the role of smartly passivated carbon nanoparticles (smapCNPs) in forming hydrogel networks.
• To explore an alternative to salt ions for creating functional hydrogel platforms for muscle tissue engineering.

Main Methods:

• Fabrication of PNIPAM hydrogels incorporating smapCNPs.
• Morphological analysis of the resulting phase-separated-meshwork (PhaseDMesh).
• Assessment of myoblast attachment, growth, and differentiation on the PhaseDMesh under simulated salt-imbalanced conditions.

Main Results:

• smapCNPs induced the formation of a temporally efficient PhaseDMesh.
• The PhaseDMesh morphology differed from salt-induced networks (NaCl, KCl).
• The PhaseDMesh effectively supported myoblast functions, including attachment, growth, and differentiation.

Conclusions:

• smapCNPs offer a novel approach to controlling hydrogel network formation.
• PhaseDMesh generated by smapCNPs is a viable alternative to salt ions for muscle tissue engineering.
• This study presents a promising strategy for developing advanced biomaterials for regenerative medicine.
