| Outline of Final Research Achievements |
We aimed to develop bioelectrodes that can be disassembled at arbitrary timing. We focused on cellulose to realize this. Cellulose has no decomposing enzymes in the human body and can exist stably. Also it has biocompatibility as it is used as a dialysis membrane. Moreover, it is decomposed by cellulase derived from microorganisms. Therefore, we have developed a cellulose-based electrode which is easily decomposed by injecting cellulase. First, we developed a method to make cellulose tubes of various diameters. Then an electrode composed of a plurality of cellulose tubes (imparting conductivity by injecting an electrolyte into the inside) was prepared. It was confirmed that this electrode was decomposed by implanting it into the model biogel and injecting cellulase halfway.
