Prof. Yasuaki Einaga's group (Keio Univ.) has successfully demonstrated in vivo pH monitoring using boron doped diamond and silver needles, which is jointly done with Prof. Hideyuki Saya's group (Keio Univ.). Potential applications for stomach cancer diagnosis or other stomach disorders was used as a typical example to illustrate the capabilities of this new system for in vivo pH monitoring.
