Micro-fluidics is a subspecialty or super-specialty of biomedical engineering. It has the potential to grow faster and influence the diagnostic field of medical practice.However, this information and utility of micro-fluidics is sparse among the medical fraternity. User and adviser of application of micro-fluidics and devices based on it is a medical fraternity. Hence, it is difficult for micro-fluidics to grow exponentially without strong demand from doctors and Para-medical personnel. Therefore, awareness among doctors, paramedical, and industrialists manufacturing devices in the diagnostic field is essential. More and more articles ought to be published to create such awareness. Many students and their parents in India; looking for additional fields of career, look upon biomedical engineering with a lot of hopes, but with little information about the super-specialty fields like micro-fluidics. If they get information then the growth of biomedical engineering and super specialties in biomedical engineering would spur in developing countries like India. Hence, written this over view/article to spread awareness among doctors, paramedical, engineers, scientists,industrialists, and aspiring students. This overview throws light on past, present and future scenario of micro-fluidics. It summarizes how and why the growth of micro-fluidics has become complicated. It touches the complexities created by the role of different specialities and its interactions.Mechanical engineering, biological science, genetics, electronics, physical chemistry, a diagnostic field in medical practice, commercial industry, etc. play a significant role in the application of micro-fluidics. Interaction among these fields affects micro-fluidics in general. In the end, the authors express their opinion on how to expedite the growth of the micro-fluidics industry.
