Turkevich in New Robes: Key Questions Answered for the Most Common Gold Nanoparticle Synthesis

Turkevich method for gold nanoparticle synthesis revisited.

The growth of gold nanoparticles by reduction by citrate and ascorbic acid has been examined in detail to explore the parameter space of reaction conditions. It is found that gold particles can be produced in a wide range of sizes, from 9 to 120 nm, with defined size distribution, following the earlier work of Turkevich and Frens. The reaction is initiated thermally or in comparison by UV irrad...

AMPK, MAPK and Bax in the heart: some questions answered.

The question of how Bax is activated during apoptosis to perform its role in permeabilization of mitochondrial membranes is intriguing for investigators in the wide field of cell death research. In their paper published in the Biochemical Journal in 2006, Capano and Crompton presented their discovery that simulated ischaemia causes rapid activation of AMPK (AMP-activated protein kinase) which p...
