This imaging textbook covers neuromolecular imaging from in vivo electrochemistry. It discusses how neuromolecular imaging solved the persistent problem of electrocatalysis with LIVE imaging nanotechnology and circuits designed by the author, Prof. Patricia A. Broderick. The BRODERICK PROBE® nanobiosensor is smaller than one strand of human hair, does not scar, nor produces bacterial growth, as clinically demonstrated. It details this sensor's success in clinical and research settings, the biomedical engineering involved in its manufacture, and original, tried, and trusted protocols for use by scientists and practitioners in multiple fields of brain application and sensor design.
