Kinetics and mechanism of mineral respiration: how iron hemes synchronize electron transfer rates

Chabert, Valentin ; Babel, Lucille ; Füeg, Michael P. ; Karamash, Maksym ; Madivoli, Edwin S. ; Herault, Nelly ; Dantas, Joana M. ; Salgueiro, Carlos A. ; Giese, Bernd ; Fromm, Katharina M.

In: Angewandte Chemie International Edition, 2020, vol. 59, no. 30, p. 12331-12336

Anaerobic microorganisms of the Geobacter genus are effective electron sources for the synthesis of nanoparticles, for bioremediation of polluted water, and for the production of electricity in fuel cells. In multistep reactions, electrons are transferred via iron/heme cofactors of c‐type cytochromes from the inner cell membrane to extracellular metal ions, which are bound to outer membrane...

Opening study on the development of a new biosensor for metal toxicity based on pseudomonas fluorescens pyoverdine

Chiadò, Alessandro ; Varani, Luca ; Bosco, Francesco ; Marmo, Luca

In: Biosensors, 2013, vol. 3, no. 4, p. 385-399

To date, different kinds of biosensing elements have been used effectively for environmental monitoring. Microbial cells seem to be well-suited for this task: they are cheap, adaptable to variable field conditions and give a measurable response to a broad number of chemicals. Among different pollutants, heavy metals are still a major problem for the environment. A reasonable starting point...

Effect of clustering on the heat generated by superparamagnetic iron oxide nanoparticles

Lattuada, Marco

In: CHIMIA International Journal for Chemistry, 2019, vol. 73, no. 1, p. 39–42

Magnetic nanoparticles have been the subject of enormous investigations for their potential use as cancer treatment via hyperthermia. This is due to their ability to generate heat when exposed to an external magnetic field oscillating at sufficiently high frequency. There are many different parameters that need to be considered when designing the optimal nanoparticle formulation for...
