CD BioSciences offers a comprehensive range of biophysical technology services designed to help researchers and companies evaluate and optimize the performance of biomaterials. Our state-of-the-art technology and dedicated team of professionals provide accurate and efficient evaluations to aid in research and development.

Background

Biomaterials are materials used to diagnose and treat diseases of biological systems, repair and replace defective tissues of living organisms and enhance or restore their functions. With the rapid development of biomaterials science, biomaterials are increasingly used in medical devices, drug delivery systems, tissue engineering, and other fields. The performance and properties of materials directly affect their performance and efficacy in biological environments, so accurately evaluating the performance of biomaterials has become a critical part of the research and development process.

The mechanical properties of biomaterials are critical in medical applications such as artificial joints. Key indicators for evaluating their properties include tensile strength, compressive strength, yield strength, modulus of elasticity, fatigue limit, and fracture toughness, especially in comparison with the mechanical properties of human bone. For materials that come into contact with the friction areas of the human body, wear resistance is usually measured by hardness.

Our Main Services

Mechanical Property Evaluation

• Nanoindentation testing. We offer nanoindentation technology to accurately measure mechanical properties such as hardness and modulus of elasticity of biomaterials, especially for soft tissue and other biomaterials.
• Tensile and compression testing. Through standard tensile and compression testing, we can assess the behavior of materials under different stress conditions to ensure their reliability in practical applications.
• Shear testing. Our shear tests accurately measure the strength and deformation properties of materials under shear and are widely used in the study of biomedical adhesives and composites.

Thermal Property Evaluation

• Differential scanning calorimetry (DSC). We support DSC techniques for analyzing thermal transition properties of materials, such as glass transition temperature, melting point, and crystallization behavior, to help optimize the thermal properties of materials.
• Thermogravimetric analysis (TGA). Through TGA technology, our team can determine the thermal stability and decomposition temperatures of materials to understand their thermal degradation properties and support thermal stability studies of materials.

Surface Characterization

• Contact angle measurement. Our experts measure the contact angle of a material's surface to assess its hydrophilicity or hydrophobicity, which is critical for the performance of biomaterials in biological environments.
• Surface energy measurement. Through surface energy measurements, we understand the surface chemistry of materials to help our customers optimize their surface treatment processes.

Electrical Property Evaluation

• Conductivity measurement. We can accurately measure the electrical conductivity of materials, which is particularly applicable to the study of conductive polymers and biosensing materials.
• Dielectric constant measurement. Through dielectric constant measurements, we can further understand the dielectric properties of materials to aid in the design and development of highly efficient electronic devices.

Optical Properties Analysis

• Spectral analysis. We utilize UV-visible and infrared spectral analysis techniques to evaluate the light absorption properties of materials, further supporting the application of biomaterials in optics.
• Fluorescence microscopy. We use fluorescence microscopy to observe the optical properties of materials at the microscopic scale, which is particularly suitable for biomarker and imaging applications.
