Glossary of Terms
- Ultrafine particles between 1 and 100 nanometers in size. The size is similar to that of most biological molecules and structures. Nanoparticles can be engineered for a wide variety of biomedical uses including diagnostic devices, contrast agents, physical therapy applications, and drug delivery vehicles. A nanoparticle is approximately 1/10,000 the width of a human hair. Nanoparticles are generally 1000 times smaller than microparticles.
- The manipulation of matter with at least one dimension sized from 1 to 100 nanometers. Research areas include surface science, molecular biology, semiconductor physics, and microfabrication. Applications are diverse and include device physics, molecular self-assembly, and precisely manipulating atoms and molecules.
- A spectroscopic method that uses the near-infrared region of the electromagnetic spectrum for pharmaceutical and medical diagnostics, typically measurements of blood sugar and blood oxygen levels.
- Includes the use of a number of techniques to image the structure and function of the brain, spinal cord, and associated structures.
- A broad discipline of neuroscience and biomedical engineering concerned with developing devices that can substitute a motor, sensory or cognitive function lost due to injury or disease. Examples encompass a wide range including cochlear implants, visual prosthetics, and brain-computer interfaces for conscious control of movement in paralyzed individuals.
- A medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease. Diagnostic nuclear medicine relies heavily on imaging techniques that measure cellular function and physiology.
