Custom Surface Modification for Micro/Nanosensors
- 总结
- Researchers at Purdue University have developed a unique method to create custom, functionalized surfaces for micro/nanosensors. This method combines water-absorbing spores and chemical retaining hydrogel to create a microscale "paintbrush" that can be grasped and moved by a micromanipulator, allowing the user to control the amount of chemical released and functionalize multiple areas in close proximity using completely different patterns and chemical concentrations.

- *Background
- Many micro/nanosensors used in biochemical and medical applications are functionalized by depositing a thin layer of material onto the sensor's surface. These functional chemicals must be inefficiently pipetted onto 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 microcontact printing, must be employed. However, these techniques require the creation of a preset mold that cannot be altered on demand.
