This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Scientists from Fuzhou University obtained a set of nanocarbons through self-assembling guanine molecules. Besides exhibiting intriguing properties, including relatively stable surface oxygen groups ...

Biogenic guanine crystals are naturally occurring photonic structures that underpin a range of optical phenomena in the biological world. These crystals, formed within specialised cells, exhibit ...
