In celebration of the 2015 Nobel Prize in Chemistry

27 Oct 2015

The 2015 Nobel Prize in Chemistry was jointly awarded to Tomas Lindahl, former director of Cancer Research UK’s Clare Hall Laboratories, Paul Modrich from Duke University in the US and Aziz Sancar from the University of North Carolina in the US for their “mechanistic studies of DNA repair”.

Tomas Lindahl’s research pieced together a molecular image of how base excision repairs DNA when a base of a nucleotide is damaged and subsequently managed to recreate the human repair process in vitro. The mechanism known as nucleotide excision repair, which excises damage from UV and carcinogenic substances, was then mapped by Aziz Sancar – the molecular details of this process changed the entire research field. Paul Modrich also studied the human version of the repair system. His work focused on DNA mismatch repair, a natural process which corrects mismatches that occur when DNA is copied during cell division.

The research carried out by the three 2015 Nobel Laureates in Chemistry has not only revolutionised our knowledge of how we function but also lead to the development of life – saving treatments. To celebrate these remarkable achievements, we are delighted to present a collection of recent Chemical Communications, Chemical Science and Chemical Society Reviews articles on DNA repair, FREE to read until 1 December 2015!

We invite you to submit your best research related to DNA repair mechanisms to Chemical Communications, Chemical Science and Chemical Society Reviews!

Incorporating DNA hydrogels into enzymatic biofuel cells

12 Oct 2015

I remember a time when mobile phones weren’t so power hungry, and when my phone could go a week on one charge. Admittedly, that was before it had a colour screen, internet connectivity and a hundred other bells and whistles. Increased device connectivity, in particular, has led to a huge increase in power demands and the need for better battery technology.

Wouldn’t it be marvellous if your phone battery generated its power from a wide selection of renewable sources? Khiem Van Nguyen and Shelly Minteer from the University of Utah look toward this possibility in their most recent ChemComm, which describes the use of DNA hydrogels in the production of an enzymatic biofuel cell.

The authors describe how they used the self-assembly of DNA monomers under physiological conditions to form a DNA hydrogel capable of trapping glucose oxidase, the most widely used enzyme in enzymatic biofuel cells. This DNA hydrogel remains permeable to small molecules, such as the battery fuel, whilst successfully trapping the enzyme close to the electrode surface. Enzyme immobilization on the electrode surface is critical to achieve an effective enzymatic biofuel cell, and this model biobattery was shown to have a similar performance to previously reported^ⱡglucose oxidase biofuel cells.

Entrapment of glucose oxidase in DNA hydrogel

With enzymes capable of oxidising a wide range of fuels, from alcohols and carbohydrates to amino acids, it may not be too long until a multi-enzyme biobattery is created that can be powered by the sweat from your skin. Then you’ll be able to browse the internet wherever and whenever you want…provided you have signal, of course.

To read the details, check out the ChemComm article in full:
