Summary
Surface modification of electrospun fibers using graft polymerization enhances their functionality. This study demonstrates successful conjugation of bioactive peptides, promoting specific cell adhesion for advanced biomaterials.
Area of Science:
- Biomaterials Engineering
- Surface Chemistry
- Cell Biology
Background:
- Electrospun fibers offer versatile platforms for tissue engineering and regenerative medicine.
- Surface modification is crucial for controlling cell interactions and reducing non-specific protein adsorption.
- Poly(lactide-co-glycolide) (PLGA) and poly(l-lactide) (PLA-Br) are biocompatible polymers suitable for fiber fabrication.
Purpose of the Study:
- To develop a surface-initiated (SI) polymerization method for functionalizing electrospun PLGA/PLA-Br fibers.
- To impart low-fouling properties and specific cell-binding capabilities to the fiber surface.
- To investigate the conjugation of bioactive peptides for enhanced cell adhesion.
Main Methods:
- Surface-initiated Cu(0) mediated polymerization was used to graft copolymers onto electrospun fibers.
- Copolymers incorporated N-acryloxysuccinimide (NAS) for peptide conjugation and low-fouling monomers (DMA, HPA, NAM).
- Surface analysis techniques confirmed peptide conjugation, and cell culture studies assessed cell attachment.
Main Results:
- Successful grafting of copolymers onto the electrospun fiber surface was achieved.
- Conjugation of both nonbioactive (RAD) and bioactive (RGD) peptides was confirmed via amino acid analysis.
- Cell culture experiments demonstrated RGD-mediated specific cell attachment, particularly at high peptide densities.
Conclusions:
- Surface-initiated polymerization is an effective strategy for functionalizing electrospun fibers.
- The developed method allows for the precise control of surface properties, including cell adhesion.
- These functionalized fibers hold potential for applications in tissue engineering and cell-based therapies.

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...
