The Center for Devices and Radiological Health (CDRH) continues to build the Center’s knowledge base and experimental expertise regarding nanotechnology, including through collaborating on research projects with other stakeholders. All research projects related to nanotechnology are currently conducted in the Office of Science and Engineering Laboratories.
CDRH nanotechnology regulatory science research projects are primarily addressing the following:
- Understanding the mechanistic behavior of nanomaterials from physical, chemical and biological aspects including:
Physico-chemical stability/interaction of nanomaterials and their interaction with nanoscale surfaces; Toxicity and behavior of nanomaterials in in-vitro and in-vivo environments; Biocompatibility of nanomaterials exposed to blood elements; and Gene expression models for evaluating adverse reactions to nanomaterials. A number of these studies are being conducted using silver nanomaterials as silver is used in many devices for its antimicrobial properties.
- Advancing knowledge regarding the characterization of nanomaterials including:
Existing methods/technologies for characterization of nanomaterials and their limitations; Characterization of optical coherence tomography-based imaging approaches; and Optical nanobiosensors for minimally invasive intracellular monitoring.
