Time evolution of nanoparticle-protein corona in human plasma: relevance for targeted drug delivery.

When nanoparticles (NPs) enter a biological fluid (e.g., human plasma (HP)), proteins and other biomolecules adsorb on the surface leading to formation of a rich protein shell, referred to as "protein corona".

Free Ca2+ as an early intracellular biomarker of exposure of cyanobacteria to environmental pollution.

Calcium functions as a versatile messenger in a wide variety of eukaryotic and prokaryotic cells. Cyanobacteria are photoautotrophs which have a great ecological impact as primary producers. Our research group has presented solid evidence of a role of calcium in the perception of environmental changes by cyanobacteria and their acclimation to these changes.
