What Is Physical Characterization?

Physical Characterization refers to comprehensive analytical studies conducted to determine and evaluate the physical properties of a product, material, or device. These tests are of critical importance in assessing the quality, performance, and safety of medical devices, pharmaceutical products, biomaterials, nanomaterials, biocidal products, and various industrial materials.

A product’s physical properties can directly affect not only its performance but also its biological safety, stability, and suitability for its intended use. For this reason, physical characterization studies are recognized as one of the fundamental components of product development, quality control, and regulatory processes.

At NanoTox, through our Physico-Chemical Test Unit, we offer physical characterization services in compliance with international standards, supported by our advanced analytical instrumentation and team of experts.

The Purpose of Physical Characterization Tests

Physical characterization studies aim to determine the physical properties of products using scientific methods.

Through these studies:

• Product properties are defined in detail,
• Product performance is evaluated,
• Batch-to-batch consistency is verified,
• Quality control processes are supported,
• Regulatory requirements are met.

The data obtained contributes to the scientific demonstration of product safety and performance.

Why Is Physical Characterization Important?

A material’s physical properties can directly influence its area of application and biological interactions. Accurately determining physical properties is particularly important for medical devices and nanomaterials.

Physical characterization studies are

• widely used in:
• product development processes,
• quality control applications,
• regulatory submissions,
• biocompatibility assessments,

and stability studies.

Physical Parameters Evaluated

Within the scope of Physical Characterization, various parameters can be evaluated depending on the product’s structure and intended use.

Key analyses:

• Particle size and distribution,
• Morphological structure analysis,
• Surface properties,
• Density determination,
• Porosity analysis,
• Viscosity measurements,
• Moisture determination,
• Evaluation of mechanical properties,
• Thermal property analyses,
• Solubility and dispersion properties.

These parameters provide comprehensive information about the product’s quality profile.

Analytical Techniques Used

Physical characterization studies at NanoTox laboratories are conducted using various advanced analytical techniques tailored to the product’s properties.

Commonly used methods:

• Dynamic Light Scattering (DLS)
• Laser Diffraction Analysis
• Scanning Electron Microscopy (SEM)
• Differential Scanning Calorimetry (DSC)
• Thermogravimetric Analysis (TGA)
• Zeta Potential Measurements
• Image Analysis Systems
• Rheological Analyses

These techniques ensure high accuracy and reproducibility.
