Renal‐Clearable PEGylated Porphyrin Nanoparticles for Image‐Guided Photodynamic Cancer Therapy

Nanomaterials with renal clearance from the body within a reasonable timescale have shown great promises in the area of nanomedicine recently. However, the integration of theranostic and renal clearance properties into a single ultrasmall nanostructure remains a great challenge. Herein, meso ‐tetra(4‐carboxyphenyl)porphyrin (TCPP) structure is utilized as a model, for the first time using noninvasive dynamic positron emission tomography (PET)...
