Abstract

Abstract : We demonstrate the feasibility of subcutaneously implanted fluorescent diamond microparticles as a temperature probe for the non-contact measurement of internal body temperature using a homemade wide-field optically detected magnetic resonance imager. Abstract : We constructed a highly sensitive fluorescence wide-field imaging system with a microwave source, implanted fluorescent diamond microparticles ("microdiamonds") subcutaneously into the dorsal skin of a mouse after sacrifice, and demonstrated the feasibility of using optically detected magnetic resonance (ODMR) to measure internal body temperature in a mammal.
