Advances in H2 sensors for bioanalytical applications

H-2 sensors have been receiving more attention, especially with the development of H-2 medicine and biodegradable alloys that produce H-2. The H-2 sensors discussed in this review are primarily the electrochemical, chemochromic metal oxide, and color indicator sensors. This review focuses on the bioanalytical application of these existing H-2 sensors. The performance parameters of these sensors are reviewed to aid in identifying and selecting appropriate sensors for practical applications. (C) 2016 Elsevier B.V. All rights reserved.
