In this work, a new imaging method employs the light scattering property of environmentally friendly TiO2 spheres, also known as Mie scattering, and can overcome these issues. TiO2 is known to be harmless to humans and has been widely used in environmental engineering to deal with waste and in bioapplications because of its excellent photocatalytic property and nontoxicity. There are some advantages in using TiO2 scattering as a detection source.
