Fabrication and Characterization of Biodegradable Polymer Nanocomposites for Bone Tissue Engineering Applications

The project thesis titled “Fabrication and Characterization of Biodegradable Polymer Nanocomposites for Bone Tissue Engineering Applications” aims to develop innovative materials that can be used in the field of bone tissue engineering. Bone tissue engineering is a rapidly growing field that focuses on creating materials that can replace or repair damaged bone tissue. Biodegradable polymer nanocomposites have shown great promise in this field due to their biocompatibility, mechanical properties, and ability to degrade in the body over time.

Objectives

Develop biodegradable polymer nanocomposites with enhanced properties for bone tissue engineering applications.
Characterize the mechanical, thermal, and biological properties of the fabricated nanocomposites.
Evaluate the biocompatibility and degradation behavior of the nanocomposites in vitro and in vivo.
Assess the potential of the fabricated nanocomposites for use in bone tissue engineering applications.

Methodology

The project will involve the following steps:

Selection of biodegradable polymers and nanoparticles for the fabrication of nanocomposites.
Fabrication of biodegradable polymer nanocomposites using techniques such as solvent casting, melt blending, or electrospinning.
Characterization of the mechanical properties of the nanocomposites using techniques such as tensile testing and nanoindentation.
Evaluation of the thermal properties of the nanocomposites using techniques such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
Assessment of the biological properties of the nanocomposites through cell culture studies to determine their biocompatibility and ability to support cell growth.
Investigation of the degradation behavior of the nanocomposites in simulated biological conditions and in vivo studies.
Analysis of the potential of the fabricated nanocomposites for bone tissue engineering applications through scaffold fabrication and testing.

Significance

The development of biodegradable polymer nanocomposites for bone tissue engineering applications has the potential to revolutionize the field by providing materials that can be tailored to meet specific mechanical and biological requirements. These materials could offer a more cost-effective and sustainable alternative to traditional materials used in bone tissue engineering, such as metal implants or autografts. Furthermore, the biodegradable nature of the nanocomposites could eliminate the need for additional surgeries to remove implants, reducing patient discomfort and complications.

Overall, this project has the potential to contribute significantly to the advancement of bone tissue engineering and improve outcomes for patients requiring bone repair or replacement.
