s A Procedural Excursion of Micro Needles for Drug Delivery Systems

Background: MEMS (Micro Electro-Mechanical System) has many applications in various fields. Objective: Development and fabrication of micro needle for biomedical application is one of that area. Method: Application of micro to nano-scale technology in fabrication process, yields wide range of progress and produces micro mechanical devices, which provide easy transport of biological fluids into or away from living body with less effort or pain. Conclusion: This paper presents the excursion of solid to hollow micro needles, considering their shapes, materials, with different fabrication processes. This survey discusses the application on specific body parts and drug delivery systems. Our paper suggests that hollow tubes are most effective design for application.
