ISO 10993 15 Chemical Stability of Nanoparticles in Medical Devices
The ISO 10993-15 standard is a critical component of medical device development, ensuring that nanomaterials used in medical devices are chemically stable and do not degrade or leach under expected conditions. This service focuses on the rigorous testing protocols outlined in this international standard to assess chemical stability specifically for nanoparticles incorporated into medical devices.
Nanoparticles within medical devices can significantly alter their performance, biocompatibility, and safety profile depending on their chemical properties and interactions with physiological environments. The primary goal of ISO 10993-15 is to ensure that these nanoparticles remain chemically stable under the anticipated use conditions of the device. This stability ensures that the nanoparticle does not undergo degradation processes such as hydrolysis, oxidation, or reduction, which could lead to the release of toxic substances into the body.
The standard applies to a wide range of medical devices where nanoparticles play a critical role in their functionality, including drug delivery systems, diagnostic tools, and tissue engineering scaffolds. The testing protocols are designed to mimic real-world conditions that these devices might encounter during storage, transportation, and patient use. By adhering to ISO 10993-15, manufacturers can ensure that the nanoparticles within their devices remain chemically stable throughout the product lifecycle.
Chemical stability is particularly important in medical devices because any degradation could result in the release of harmful substances into the body, leading to adverse effects on patient health. The standard provides a framework for testing these nanoparticle-containing devices to ensure that they meet safety and efficacy requirements before being marketed to the public. This service ensures that your company complies with international standards, thus safeguarding the integrity of your medical device.

Applied Standards
The ISO 10993 series of standards is widely recognized for its comprehensive approach to medical device testing and evaluation. ISO 10993-15 specifically addresses the chemical stability of nanoparticles in medical devices, providing a standardized methodology for assessing this critical aspect.
| Standard | Description |
|---|---|
| ISO 10993-15:2017 | Chemical stability of nanomaterials in medical devices, including nanoparticles and their potential for release into the body. |
| ASTM F2084 | Standard practice for characterization of nanoscale materials used in medical devices. |
| IEC 62321 | Guidelines for the design and manufacturing of electrical equipment, which can indirectly impact nanoparticle stability in certain contexts. |
The combination of these standards ensures a holistic approach to evaluating the chemical stability of nanoparticles in medical devices. Our laboratory employs these internationally recognized guidelines to provide accurate and reliable test results that meet regulatory requirements.
Scope and Methodology
| Test Parameter | Description |
|---|---|
| Nanoparticle Sample Preparation | Involves dispersing the nanoparticles in a suitable medium to simulate real-world conditions. |
| Exposure Conditions Simulation | Mimics storage and use conditions, including temperature, humidity, and light exposure. |
| Analytical Methods | Includes XPS, FTIR, DSC, and other techniques to monitor nanoparticle composition over time. |
| Data Analysis | Uses statistical methods to determine the extent of chemical changes in nanoparticles during testing. |
The ISO 10993-15 standard requires thorough preparation and simulation of real-world conditions. This begins with dispersing the nanoparticles into a medium that mimics physiological environments, such as saline or phosphate-buffered solutions. The samples are then exposed to various stressors including temperature cycling between extremes (e.g., -40°C to 85°C), humidity levels up to 93%, and light exposure using xenon lamps.
Throughout the testing period, which can last several weeks depending on the stability of the nanoparticle, we continuously monitor for any chemical changes. This involves regular sampling intervals followed by rigorous analysis using advanced analytical techniques like XPS, FTIR, and DSC to detect subtle shifts in nanoparticle composition or morphology.
Data analysis plays a crucial role in interpreting these results. Statistical methods help determine whether observed changes are significant enough to impact the safety and efficacy of the device. This information is then compiled into detailed reports that provide comprehensive insights into the chemical stability of the nanoparticles under test conditions.
