Analyst Issue 2 now online!

The latest issue of Analyst is now online: take a look at these beautiful covers and read all about the research behind them.

Analyst Issue 2

Front cover: Liu and Boyd, Analyst, 2013,138, 391-409

Our outside front cover features the work of Qingtao Liu and Ben J. Boyd from the Monash University, Parkville, Australia. In their critical review, the authors offer a detailed overview on the recent use of liposomes in the field of biosensors and bioanalysis.

Liposome surface structures can be modified in a way that they recognise a wide range of analytes. Thus, the possibility to translate liposomes into commercial devices for biosensing is discussed.

The inside front cover gives a snapshot of a study from the Republic of Korea. Jong Kyu Kim and colleagues present a high performance gas sensor based on near single crystalline TiO2 array nanohelices fabricated by rotating oblique angle deposition (OAD). This new OAD method can be used to fabricate a functional electronic nose and multifunctional smart chips for in situ environmental monitoring.

On a similar subject, our inside front cover is from Stephen O’ Hagan featuring the work of  Roystone Goodacre and co-workers from the University of Manchester. This study shows how silver deposited onto copper surfaces, such as the British 2 pence coins, can be used for detection of legal or illegal substances present in solution at low concentration. The researchers used the highly fluorescent Rhodamine 6G probe to demonstrate that silver application to copper coins leads to production of substrates capable of promoting Surface Enhanced Raman Scattering (SERS). The application of different drugs to the obtained substrates was then carried out using

Analyst Issue 21 now online!

The latest issue of Analyst is online with three cover articles for you to enjoy.

Outside front cover, Analyst, Issue 21, 2012

Chung et al., Analyst, 2012, 137, 4921

The very informative front cover comes from Yu-Chang Tyan and Tze-Wen Chung from the National Yunlin University of Science and Technology and Kaohsiung Medical University, respectively, and colleagues from Taiwan. In their study they proposed a new approach for the detection of proteins to assess the response of fibroblasts to a material surface. Biomaterials play an important role in regenerative medicine and drug delivery, therefore the interactions between biomaterial surfaces and cells are important to characterize cell proliferation, differentiation and regeneration of tissues.

Kaminskyj et al., Analyst, 2012, 137, 4934

We head to Canada for our inside front cover. Kathleen M. Gough and Susan G. W. Kaminskyj from the University of Manitoba and the University of Saskatchewan, together with colleagues have been studying the filamentous fungi Aspergillus. This fungi can can affect humans through their roles in biotechnology and recycling, and can also be responsible for disease.

What they have discovered is that Surface Enhanced Raman Scattering (SERS) can provide chemical information on materials that are in close contact with appropriate metal substrates, in this case nanopatterned gold surfaces and gold nanoparticles (AuNPs). They have created conditions for AuNP formation within and on the surface of Aspergillus nidulans hyphae in order to explore their potential for SERS analysis.

Issue 20 now online

Analyst 2012, Issue 20, front cover

Front cover: Konorov et al., Analyst, 2012, 137, 4662-4668

The latest issue of Analyst is online, with three cover articles for you to enjoy.

Our stunning front cover comes from the groups of Professor Robin Turner and Professor Michael Blades at the University of British Columbia, Vancouver, Canada. Their study establishes the utility of Raman spectroscopy to non-invasively detect biologically relevant changes in live cells exposed to conditions known to trigger autophagy.

The centre image is a differential interference contrast image of two MCF-7 cells, a human breast cancer cell line, after being starved of glutamine for two days.

The surrounding four images are chemical maps based on Raman microspectroscopy of the same two cells rendered from chemically-selective band intensities that indicate the spatial distributions of DNA and RNA (upper-left); RNA only (upper-right); phospholipid (lower-left) mapped relative to nucleic acid; and hydroxyapatite (lower-right), which is a common marker for breast cancers and strongly associated with malignancy.

In each image, the red intensity indicates the highest concentration, blue the lowest.  The advantage of this type of chemical imaging, according to the authors, is that it is non-destructive and label-free.

Analyst, 2012, Issue 20, inside front cover

Inside front cover, Salter et al., Analyst, 2012, 137, 4669-4676

On the inside front cover, Dr Michael Hippler and colleagues from Sheffield University, UK, introduce a variant of cavity-enhanced Raman spectroscopy (CERS) in which diode laser radiation at 635 nm is coupled into an external linear optical cavity composed of two highly reflective mirrors. Using optical feedback stabilisation, build-up of circulating laser power by three orders of magnitude occurs. Strong Raman signals are collected in forward scattering geometry.

The authors say CERS has the potential to become a new standard method to monitor Raman active species, in particular important homonuclear gases like nitrogen, oxygen or hydrogen that can not be easily detected by alternative spectroscopic techniques.

Issue 19 now online

Analyst, 2012, Vol. 137, Issue 19, front cover

Front cover: Hopkins et al., Analyst, 2012, 137, 4408-4410

The latest issue of Analyst has landed, and as usual there are some interesting cover images and articles for you to enjoy.

On the front cover is a Communication from Rebecca Hopkins and colleagues from DSTL Porton Down, UK. They demonstrate spatially offset Raman spectroscopy (SORS) using 1064 nm excitation to detect chemicals through a physical barrier such as a container. This excitation wavelength overcomes the issue of fluorescence from the target chemical, whilst retaining the benefits of the SORS technique for through-barrier detection. The authors say these advantages have a wide range of applications in both civilian and military environments.

Issue 17 now online

Analyst 2012, Vol. 136, Issue 17, front cover

Front cover: Branagan & Bohn, Analyst, 2012, 137, 3932-3939

Take a look at the latest issue of Analyst, with two great covers and host of HOT articles for you to enjoy.

The front cover features a HOT paper from our Editorial Board Chair, Paul Bohn, and his post-doc Sean Branagan. Paul and Sean demonstrate electrochemical imaging using enhanced optical transmission (EC-EOT) by applying it to several categories of electrochemical processes, using a spectral mapping technique that can be miniaturized. They say that in future applications, the enhanced spectral information offered by EOT may be useful for separating faradaic- and non-faradaic electrochemical signals as well as spatially resolving phenomena occurring at different locations relative to the electrified interface.
