Oxygen-Sensing Paramagnetic Probes for Clinical Oximetry

Adv Exp Med Biol. 2021:1269:259-263. doi: 10.1007/978-3-030-48238-1_41.

Abstract

Electron paramagnetic resonance (EPR) oximetry based on lithium naphthalocyanine paramagnetic crystals as oxygen sensors enables direct measurement of the partial pressure of oxygen (pO2) in tissues. The method uses topical or implantable forms of these oxygen-sensing crystals embedded in a biocompatible siloxane elastomer. This article presents a summary of these sensors for EPR oximetry and their applicability for tissue oxygen measurement in the clinic.

Keywords: Electron paramagnetic resonance (EPR); MicroChip; Oximetry; OxyChip; Partial pressure of oxygen (pO2); SPOTChip.
