Methods for fabricating new types of micro-devices for biological and medical applications are disclosed. These novel methods employ microelectronics process technologies and novel process flows to fabricate micro-devices that have improved performance, flexibility and the ability for disease detection and treatment at microscopic levels. These micro-devices have reduced costs over the conventional methodologies and vehicles found in current medical treatment modalities. Micro-devices fabricated using the disclosed nano-technological techniques have significant improvements in many areas over the existing, conventional methods. Such. improvements include, but are not limited to reduced overall costs, early disease detection/diagnosis, targeted drug delivery, targeted disease treatment and reduced degree of invasiveness in treatment. Compared with existing, conventional approaches, the said inventive approach disclosed in this patent application is much more microscopic, sensitive, accurate, precise, flexible and effective. This novel approach is able to deliver a superior level of performance in medical treatments over the existing modalities.
