Nanomedicine in neuronal trauma and diseases
Nanoparticles have become a major field of exploration for medical applications. Based on their material properties, they can help to treat disease by delivering drugs to a specific area of the body to reduce side effects, diagnose diseases by enhancing detection methods (MRI or CAT scan), or a mixture of both. Regarding treatments, the use of nanoparticles can target diseased areas in the body and therefore enhance drug bioavailability and reduces dosing frequency. We are interested in employing various natural or synthetic polymers for the purpose of diagnosis and treatments in neuronal trauma and diseases. Specifically, we are interested in an effective drug carrier that can have the capability of carrying some effective compounds developed in this lab, such as potassium channel blockers and aldehyde scavengers, to be used in spinal cord and brain injury and chronic neurodegenerative diseases.
