| Many micro and nano sensors used in biochemical and medical applications are functionalized by depositing a thin layer of material on the sensor’s surface. These “functional” chemicals must be inefficiently pipetted on a larger than necessary area to ensure an even distribution. Currently there are not any simple methods to functionalize a surface in a user-defined, “on-demand” pattern. If the surface needs to be functionalized by a more complicated pattern, techniques such as micro-contact printing must be employed. However, these techniques require that a preset mold be created that cannot be altered on demand. Researchers at Purdue University have created a unique method to create custom, functionalized surfaces for use in micro/nano sensors. The invention combines water absorbing spores and chemical retaining hydrogel to create a micro-scale “paint brush” that can be grasped and moved by a micromanipulator. Advantages of this system allow the user to control the amount of chemical released, and functionalize multiple areas in close proximity using completely different patterns and chemical concentrations. Advantages: -"On-demand" functionalized surface creation -Efficient, defined, and controlled surface patterns Potential Applications: -User-friendly functionalized micro/nano surfaces |
