Porphyrin compounds take on vibrant shades of color thanks to their π electrons. The network of double bonds—also known as a ...

These porphyrins accumulate in the skin and other organs before being excreted in feces and urine (which may turn a port-wine color). Exposed to light, the porphyrins can turn caustic and destroy ...

A huge molecular wheel has set a new record as the largest aromatic ring (Nat. Chem. 2020, DOI: 10.1038/s41557-019-0398-3). The molecule could be a step toward making even bigger rings that serve ...

Porphyrin-based nanosheet filters capture nanoparticles as small as viruses (~100 nm) while maintaining high air flow. The filter, constructed from ordered porphyrin meshes on nanofiber-modified ...

THE average physician confronted with the subject of porphyrin metabolism pictures either a bewilderingly complex group of strange pigments obtained from stools and ...

Porphyrins are interesting drug delivery vehicles that can specifically accumulate in cancer cells. However, how the structure of the drug-conjugated porphyrin affects its ability to penetrate and ...
