Abstract
The present disclosure describes an imaging composition including porous silicon microparticles, and more particularly, to a biological tissue imaging composition including a composite in which oxidized porous silicon microparticles and silver nanoparticles are combined. Since a biological tissue imaging agent of the present invention, which includes a composite of oxidized porous silicon microparticles and silver nanoparticles, continuously provides an image signal without spreading in the body as compared to conventional imaging agents, it is possible to increase surgical stability by accurately identifying target tissues in vivo in an affected area.
