Fluoxetine Determination by PVC membrane and Nano-Composite Carbon Paste Electrodes

open access: yesInternational Journal of Electrochemical Science, 2011
Fluoxetine is one of the most prescribed antidepressant drug. Two kinds of potentiometric sensor were made for determination of fluoxetine. Both sensors respond based on ion-exchange mechanism.

Quantum Zeno Effect Explains Magnetic-Sensitive Radical-Ion-Pair Reactions

open access: yes, 2009
Chemical reactions involving radical-ion pairs are ubiquitous in biology, since not only are they at the basis of the photosynthetic reaction chain, but are also assumed to underlie the biochemical magnetic compass used by avian species for navigation ...
