IBEC researchers have found a way to measure the rate of electron transfer

IBEC researchers have found a way to measure the rate of electron transfer (ET) – an important process which is essential in many chemical and biological processes such as cellular respiration and photosynthesis – at the single-molecule level.

In a study published in ACS Nano () members of BEC’s Nanoprobes and Nanoswitches group describe how they used an electrochemical tunneling microscope to measure the ‘distance decay constant’ that characterises the rate of ET in redox proteins (proteins in which ET occurs). Analysis of decay constant measurements reveals differences between the reduced and oxidized states of a protein, that may be relevant to the control of ET rates in enzymes and biological electron transport chains.
