Nanomaterials for Neural Engineering
Jessica Winter, Chemical and Bioengineering
Our group is exploring the interface between neural prostheses and neurons at multiple length scales. In addition to our microscale research to improve biocompatibility of existing prosthetic devies, we are forming new types of neural prostheses using nanomaterials, including semiconductor quantum dots and magnetic nanoparticles. For example, we are exploring the potential of semiconductor quantum dots to act as miniature photo-diodes capable of producing excitatory voltages in the vicinity of neurons. These materials could be used to excite individual ion channels and may ultimately form the basis of therapeutics with unprecedented control. In addition, we are developing technology to physically manipulate neurons using magnetic nanoparticles. These particles could be used to "wire-up" neurons with each other or with electronic materials. Through these investigations we hope to enhance the function of current prosthetic devices and create novel devices that influence neurons at increasingly smaller length scales.
