ISO 29701 Solubility Testing of Nanoparticles in Biological Media
The ISO 29701 standard provides a comprehensive framework to assess the solubility and dissolution behavior of nanoparticles in biological media, which is crucial for understanding their potential impact on human health and the environment. This test is particularly important as nanomaterials are increasingly used across various industries, including pharmaceuticals, cosmetics, and electronics.
The procedure involves dispersing nanoparticles into a range of biological fluids such as water, serum, or cell culture medium under controlled conditions that mimic real-world exposure scenarios. The dissolution rate of the nanoparticles is then measured over time using advanced analytical techniques like inductively coupled plasma mass spectrometry (ICP-MS) and dynamic light scattering (DLS).
The significance of this test lies in its ability to predict whether nanoparticles will remain intact or break down into smaller particles, which can have different biological effects. For instance, certain nanoparticle species may release toxic ions or fragments that could be harmful if they enter the body. By conducting ISO 29701 tests, manufacturers and researchers can ensure that nanomaterials are safe for use in consumer products.
Our testing facility utilizes state-of-the-art equipment to perform these experiments with precision and accuracy. Our team of experts follows strict protocols outlined by the standard to ensure reliable results.
