Advanced Tools for Tissue Regeneration: Role of Bionavis MP-SPR in Wound Healing Research

Wound healing and tissue regeneration involve a tightly regulated sequence of biological processes—cell migration, adhesion, proliferation, matrix remodeling, and immune modulation. To optimize therapeutic strategies, researchers need technologies that can capture these complex interactions in real-time and under physiologically relevant conditions. Multi-Parametric Surface Plasmon Resonance (MP-SPR) from Bionavis stands out as one such tool, offering unparalleled sensitivity and kinetic detail in studying biomolecular interactions and biomaterial performance.

What is Bionavis MP-SPR?

Bionavis MP-SPR systems extend traditional SPR by capturing full angular and spectral SPR curves at multiple wavelengths. This approach allows simultaneous determination of:

• Binding kinetics(association/dissociation rates)
• Refractive index
  
• Layer thickness (0.5–1000 nm)
  
• Conformational changesin biomolecular assemblies

These capabilities are highly relevant to tissue regeneration research, particularly for analyzing biomaterial surfaces, growth factor interactions, and immune-modulatory molecules used in wound healing scaffolds or dressings.

Applications of Bionavis MP-SPR in Tissue Regeneration

1. Biomaterial Surface Characterization

The interaction between cells and scaffolds is governed largely by the surface chemistry and structure of the biomaterial. MP-SPR can:

• Measure protein adsorption profiles(e.g., fibronectin, vitronectin, collagen) on biomaterials.
• Analyze adsorption layer thicknessand surface density, which influence cellular adhesion and migration.
• Evaluate the stability of coating materialssuch as silk fibroin, chitosan, or PEGylated layers.

📊 Example: In a study involving collagen-mimetic hydrogels, MP-SPR was used to evaluate fibrinogen and fibronectin adsorption. Results showed a direct correlation between layer thickness (~10–15 nm) and endothelial cell adhesion potential.

2. Growth Factor and Cytokine Binding

Growth factors such as VEGF, PDGF, and TGF-β play essential roles in angiogenesis and cellular proliferation during wound healing. MP-SPR enables:

• Kinetic profiling of growth factor-receptor binding (e.g., VEGF-VEGFR2).
• Optimization of growth factor immobilization on scaffolds.
• Monitoring real-time release kineticsfrom biomaterial carriers.

📊 Case Study: Researchers used MP-SPR to evaluate VEGF binding affinity to heparin-functionalized collagen. KD values in the range of 10⁻⁸ M confirmed strong, sustained interactions suitable for controlled-release therapies.

3. Monitoring Stem Cell and Immune Cell Interaction Markers

MP-SPR is capable of studying:

• Mesenchymal stem cell adhesionvia integrin binding to ECM ligands.
• Immune response markers, such as the binding of TGF-β or IL-10 to macrophage surface proteins.
• Interaction dynamics of regulatory T cells (Tregs)with therapeutic targets in inflamed tissue environments.

📊 Published Insight: Studies from Monash University on Treg activation involved measuring transcription factor interactions and cytokine release patterns—data that could be complemented by MP-SPR to understand binding events on a functionalized surface.

Integration with Regenerative Material Development

MP-SPR is an ideal analytical platform during early-stage biomaterial screening and preclinical development of wound dressings, injectable scaffolds, and cell delivery matrices:

• Evaluate real-time swelling, degradation, and remodelingof biohydrogels.
• Quantify drug or protein release ratesinto simulated wound environments.
• Track ECM remodeling enzymes(e.g., MMPs) and their inhibitors.

📊 Marine Biopolymers: In a recent review, agarose, alginate, and chitosan were shown to promote tissue regeneration. MP-SPR has been used to assess their protein-binding profiles and immune cell interaction potential, helping researchers optimize formulations.
