A new and novel method utilizing current nano-technological processes for fabricating a range of micro-devices with significantly expanded capabilities, unique functionalities at microscopic levels, enhanced degree of flexibilities, reduced costs and improved performance in the fields of bioscience and medicine is disclosed in the within patent application. 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, 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. While microelectronic processes have been used for fabricating integrated circuit (&ldquo；IC&rdquo；) devices such as microprocessors, digital signal processors (&ldquo；DSP&rdquo；) and memory chips for the past two to three decades, their use has not been extended to most areas of bioscience and medicine. While there have been some application of micro-chips used in the area of laboratory diagnostic tests such as gene/DNA mapping and potential tests for diseases, their meaningful application in the areas of in-vivo diagnosis, drug delivery and disease treatments have not been utilized and are basically non-existent in the current state of the art. The disclosure herein utilizes these techniques to manufacture micro-devices for use in biological and medical applications as a microscopic way of treating disease.
