Carbon dots (CDs) are fluorescent nanomaterials used extensively in bioimaging, biosensing and biomedicine. This is due in large part to their biocompatibility, photostability, lower toxicity, and lower cost, compared to inorganic quantum dots or organic

Functional and structural mimics of superoxide dismutase enzymes [PDF]
Superoxide dismutase (SOD) enzymes form important defence line in living organisms. Through a dismutation reaction they transform the highly reactive superoxide radical ion to oxygen and hydrogen peroxide.

ABSTRACT Plants have evolved highly efficient strategies to maintain iron (Fe) homeostasis. In this study, we investigate the impact of arbuscular mycorrhizal (AM) symbiosis on the Fe‐deficiency response and ionomic profile of tomato plants, as well as how Fe availability affects AM symbiosis.

ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.

Radiation damage in sub‐Ångström resolution macromolecular crystallography: a low‐dose study
This first systematic radiation‐damage study at 0.55 Å resolution reveals extensive small conformational changes in response to dose. The findings demonstrate the benefits of using large crystals fully bathed in a large `top‐hat' beam with a uniform fluence profile, together with low‐dose data‐collection protocols, for sub‐Ångström structure ...
