Hot Article: Electrochemically assisted bacteria encapsulation in thin hybrid sol–gel films

12 Jul 2013

By James Serginson, web writer.

Electrochemically assisted bacteria encapsulation in thin hybrid sol–gel films

Bacteria are typically cast in one of two roles: either vile, disease-causing microkillers evolving faster than science can keep up or as benevolent, yoghurt-borne wardens of the digestive system. An increasingly important third job is that of efficient, microscopic machines capable of producing complex biomolecules such as DNA or insulin, working as biosensors or acting as highly-specific catalysts.

A recent paper by Ghach et al. focuses on encapsulating bacteria in thin silica films in order to make them more practical for use in bioelectronic sensors. They developed two methods of preparing films. Firstly, a two-step process where bacteria were immobilised on an indium tin oxide (ITO) electrode before a silica-based sol was deposited over them. The second method was a one-step where the sol and the bacteria were deposited at the same time (shown above). Trehalose, poly(ethylene glycol) (PEG) and chitosan were also present in the sol to improve cell viability.

Using the two-step process, the researchers found that by varying deposition times it was possible to prepare films with a thickness between 82 nm and 2 μm. With optimum conditions, 95% cell viability was observed after one month. For the one-step process, which resulted in a composite film containing homogeneously dispersed bacteria, it was shown that encapsulated luminescent E. coli still exhibited 50% luminescence after storage for four weeks.

*The Impact Factor provides an indication of the average number of citations per paper. Produced annually, Impact Factors are calculated by dividing the number of citations in a year by the number of citeable articles published in the preceding two years. Data based on 2012 Journal Citation Reports®, (Thomson Reuters, 2013). There will be an impact factor for either Journal of Materials Chemistry, or Journal of Materials Chemistry A, B and C, every year. The 2014 Journal Citation Reports® will include the last impact factor for Journal of Materials Chemistry, and the first impact factors for the three new journals.

^#Immediacy Index is the numbers of citations in a given year to papers published in that year.

Themed Issue on Nanotechnology of Multifunctional Materials

23 May 2013

By Sam Keltie, Executive Editor.

Journal of Materials Chemistry C is planning to produce a themed issue on Nanotechnology of Multifunctional Materials in 2013. Please e-mail the editorial office at materialsC-rsc@rsc.org, if you are interested in contributing an article.

The Guest Editors of the issue will be Professor Fabio Biscarini (University of Modena and Reggio Emilia, Italy) and Dr Massimiliano Cavallini (Institute of Nanostructured Materials, CNR Bologna, Italy).

Molecular and polymeric multifunctional materials are relevant to many fields of technology, from optoelectronics, spintronics, information storage, magnetism, biosensing and energy production. They are designed to combine multiple properties and functional groups to control their self-organisation into a variety of supramolecular architectures. The technological control should not be limited to either the molecular level or in bulk, instead should span the different length scales. Devices require the control of size and position, and the integration of different materials.

The deadline for the receipt of manuscripts for this themed issue is 1 July 2013

Manuscripts can be submitted using the RSC’s online submissions service. Please clearly mark that the manuscript is submitted for the themed issue on ‘Nanotechnology of Multifunctional Materials’.

Please would you inform the editorial office by e-mail at materialsC-rsc@rsc.org as soon as possible if you plan to submit to the issue and whether your contribution will be original research or a review-type article. We would like to have a list of authors who intend to contribute as soon as possible.

Taking the shine off: Journal of Materials Chemistry A article in Chemistry World

Painting used to test method with a white dot to show test area (left). Test area before (middle) and after (right) cleaning

Painting restoration could be yet another application for ionic liquids, new research shows. The work paves the way to safer procedures for cleaning paintings.

Over time, varnish applied to the top of oil paintings tends to yellow and accumulate dirt. Current conservation methods involve cleaning paintings with organic solvents but these pose environmental and health risks. Now, researchers in Portugal have demonstrated that using ionic liquids is a less toxic way to remove varnishes from paintings.

Hot Article: The reaction between Nafion sulfonyl fluoride precursor membrane and 1,4-dimethylpiperazine does not yield reliable anion-exchange membranes

13 May 2013

By Katie Bayliss, Development Editor.

This article has been made free to access for a short time!

Alkaline polymer electrolyte fuel cells (APEFCs) have received much attention as next generation, platinum free fuel cells for future energy applications. A significant challenge to the development of APEFCs is the fabrication of suitable anion-exchange membranes (AEMs) for use within the fuel cells. Recently, a synthesis based on the reaction of Nafion® sulfonyl fluoride membranes with diamine 1, 4-dimethylpiperazine has been proposed as a method for making AEMs.

In this Hot Article, Varcoe and co-workers investigate the Nafion-based systems using a combination of vibration spectroscopy, solid state NMR and measurement of ion exchange capabilities. They find strong evidence that membranes synthesised by the reported procedure are predominantly in the cation-exchange form. These findings suggest that, contrary to previous reports, the membranes are not suitable for use in electrochemical devices requiring anion exchange polymer electrolytes, such as APEFCs.
