Allen Hill

Professor Allen Hill FRS

Fellow


Elected: 1990

Biography

Allen Hill’s revolutionary research across the areas of inorganic biochemistry and protein electrochemistry has enabled the development of electronic biosensors that can make an accurate diagnosis from a tiny sample of blood. Most notably, Allen’s work led to the glucose sensor, which has transformed the ability of diabetics to manage their condition.

When glucose enters the sensor, it is broken down by an enzyme in a process that produces electrons in proportion to the total glucose present. Thus, to detect the glucose, these electrons must be collected and transferred to an electrode, through which current then flows. Allen was able to provide a stable way to transfer these electrons using the iron-containing compound ferrocene, ensuring the reliability of the device.

His earlier research centred on the role of metal-containing proteins and complexes in biochemistry. This includes work to investigate the chemistry of vitamin B12, which contains a central cobalt ion and plays an important role in the synthesis and regulation of DNA and the metabolism of fats and protein in cells.
