Joe Wang receiving the Spiers Memorial Award from Faraday Division President Graham Hutchings

Professor Joseph Wang is the 2013 winner of the Spiers Memorial Award announced at Faraday Discussion 164 last week in Durham, UK.

Faraday Discussions are unique international discussion meetings which focus on rapidly developing areas of physical chemistry and its interfaces with other scientific disciplines, with the aim to provide a forum with academic experts and users. A number of meetings are organised each year by the Faraday Division , the most recent in association with the Analytical Division of the RSC, with the meeting having an analytical chemistry component.

The meeting was held at Durham University and focused on Electroanalysis at the Nanoscale, a growing area of interest which finds applications in various disciplines including biology, fuel cells, material science and sensing. The Spiers Memorial Award was presented by Faraday Division President Graham Hutchings to to the introductory lecturer who provided a most stimulating and wide-ranging introduction to the discussion.

Joe Wang is a Distinguished Professor and Vice Chair of Nanoengineering at the University of California, San Diego (UCSD), USA, is an Honorary Professor from 6 different universities and recipient of two National American Society Awards for Electrochemistry and Instrumentation. Research in his laboratory is focused on nanobioelectronics, an emerging field aimed at integrating nano- and biomaterials with electronic transducers. His highly multidisciplinary research combines fundamental studies with forward-looking engineering efforts.

With his work, Professor Wang has provided great contributions to the areas of electroanalytical chemistry and nanobiotechnology and highlighted the most recent advances in the development of nanomotors, nanoactuators, electrochemical biosensors and wearable sensor systems.

An new aptasensing platform for detection of multiple analytes

Jennifer A. Dougan is a guest web-writer for Analyst. She is currently a Post-Doctoral Research Associate at Imperial College London, UK.

Detecting multiple target species simultaneously via a single detection mechanism remains an attractive goal for biologically relevant studies. 

Ruo Yuan and Jingdong Peng from the College of Chemistry and Chemical Engineering, Southwest University, China, have successfully developed a multiplexed electrochemical sensor for two biological targets.

Multiplexed electrochemical sensor for two biological targets

In the study, gold nanoparticles were electrochemically deposted on a highly polished glass carbon electrode and functionalised by thrombin- and ochratoxin A-binding apatmers. In the presence of the targets, an exonuclease digestion occurred allowing the target molecules to be recycled. The single stranded product of the exonuclease digestions were then used as initiation sequences for concatamer reaction designed to introduce two distinct electrochemically active species in a sequence specific manner. Only by the initial presence of either target would the related concatamer and, by extention, the electroactive species be present.

By this elaborate system of aptamer binding, exonuclease digestion, concatamer reaction and electrochemical detection the researchers were able to simultaneously detect thrombin, a blood-clotting protein, over the range 0.1 pM – 40 nM and ochratoxin A, a nephrotic toxin, over the range 0.4 pM – 35 nM.

Analyzing Century Old Blood Samples with DART-MS

Laura Ruvuna is guest web writer for Analyst. She is currently a PhD student at Northwestern University, Evanston, Illinois, USA.

Typically dried or degraded blood samples at crime scenes are positively identified via a catalytic reaction with the haem protein, which produces a colored signal or interacts uniquely with light. In addition to blood, other proteins can undergo the same reaction, yielding inaccurate results. This high failure rate makes these tests unreliable and requires further analysis in a laboratory.

Conservators at the Detroit Art Institute in collaboration with chemistry researchers in the US used direct real time mass spectrometry (DART-MS) for the detection of degraded blood samples. This required little sample preparation, when compared to other standard conservation techniques such as HPLC and GC-MS, and identified the haem protein in the coating of an African Komo mask. In addition to cultural artifacts, this methodology can potentially be applied in forensic investigations. The authors detected haem peaks from both myoglobin and haemoglobin quickly and with greater specificity than the simple techniques described previously.

What does it mean to be an “Analyst”?

Pui Sai Lau is a guest web writer for Analyst and Analytical Methods. She is currently a PhD student at McMaster University, Hamilton, ON, Canada.

The Thinker

The Thinker (from The Bubble Chamber blog)

There appears to be many journal titles that contain the word “analyst” in some form. Examples include Analytical Biochemistry, Analytical Chemistry, Analytica Chimica Acta, Analytica, Journal of Analytical Toxicology, Analytical Methods, and of course, Analyst.

With so many variations of analytical journals available, some effort is needed to determine the best fit when submitting a manuscript for publication. This process requires classification of your own area(s) of research, which can be surprisingly challenging.

Take for instance, the areas of biochemistry, chemical biology, and biological chemistry. The prefix of each word appears to form the suffix of the next, and vice versa. In fact, if all of these words are to be read one after another, the whole phrase sounds more like a tongue-twister! While each of these respective scientific fields is specialized in its own right, some ambiguity still remains upon deeper contemplation of what exactly each field encompasses and what it does not. Differences among the fields can become more difficult to discern, the boundaries that separate them become less defined, and these multi-disciplinary approaches begin to converge into common research goals.

An underlying factor that unifies various scientific areas is the requirement of high quality analysis.

So, what does it mean exactly to be an analyst? Perhaps it is someone who can decipher the fine details of chemical reactions, molecular structures, computational algorithms, and biochemical mechanisms; then piece together these components into an overall composite for scientific understanding. Perhaps it is someone who is well-attuned with his/her surroundings, and inspired to find answers to everyday peculiarities. It may be someone who foresees the raw potential in new discoveries, even before direct applications are demonstrated. Or simply someone who loves scientific questioning and appreciates the sake of learning for what it is worth in and of itself. Whatever the precise definition is, frequent publications and updates on the latest scientific breakthroughs by journals like Analyst continue to ignite the passion of those who are motivated to discover and to know more.

So what does being an Analyst mean to you? Share your thoughts with us by commenting below.
