General Conclusions and Future Perspectives
In this thesis, various applications of Soft-Probe-SECM for bio-imaging and bio-sensing of human, animal and plant tissue were demonstrated. Soft probes are easy to prepare and the SECM instrumentation can be kept simple and affordable bringing many advantages for tissue analysis. In Chaps. 1 and 2, the fabrication of different types of soft probes including conventional single soft stylus, stair case shaped single soft probe, conventional soft linear array, and newly developed soft spider probe that contains eight microelectrodes independently can slide over rough surface features. Thanks to advanced laser microfabrication tools, the tips of the soft probes could be made significantly smaller allowing a more independent brushing of rough surfaces, such as thick tissue.
