Nanotoxicology examines how nanomaterials interact with biological and environmental systems, including how nanoparticle size, composition, surface chemistry, and other physicochemical properties influence potential toxicity. Nanosafety focuses on understanding and engineering these characteristics to support the safer use of nanomaterials. Together, these disciplines provide the research foundation needed to develop and use engineered nanoparticles safely and sustainably.

Precisely Engineered Nanoparticles for Nanotoxicology Research
Understanding nanoparticle structure-activity relationships requires well-controlled materials. By comparing highly characterized nanoparticles while changing one parameter at a time, researchers can isolate how individual particle characteristics influence biological or environmental responses.
Key variables include:
- Size and aggregation state: Evaluate size-dependent effects while minimizing aggregation as a confounding variable.
- Shape: Compare how nanoparticle morphology influences interactions with biological or environmental systems.
- Surface chemistry: Investigate the effects of surface charge, coatings, and functional groups.
- Material composition: Compare different core materials and associated behaviors such as dissolution.
These controlled comparisons help researchers identify trends associated with individual nanoparticle properties and apply those findings to more complex or industrially relevant materials. For additional guidance, see our resources on nanoparticle selection for nanotoxicology and experimental use of nanoparticles.
Highly Characterized Nanoparticles for Controlled Studies
nanoComposix has supported nanoparticle research since 2004, providing precisely engineered materials across a broad range of sizes, shapes, compositions, and surface chemistries. Researchers can use these variations to build comparative studies while limiting unnecessary differences between test materials.
Low-endotoxin formulations are available for many gold and silver nanospheres at 1 mg/mL and are filtered through a 0.22 µm membrane. Each lot includes batch-specific characterization data such as TEM, DLS, zeta potential, and UV-Vis, providing a well-defined starting material for biological and environmental studies.
