Analytical Sciences in Brazil – web themed issue

Analyst and Analytical Methods recently joined forces to produce a web themed issue on Analytical Sciences in Brazil, highlighting the growth of the field of analytical science in Brazil with the aim to provide a showcase for some of the best researchers in this area.

As an extra special feature of this issue, please read below the introductory Editorial from Guest Editors, Professor Ivo M. Raimundo Jr and Professor Boris Mizaikoff, translated into Portuguese.

Analytical Sciences in Brazil – Editorial

 The use of EEM fluorescence data and OPLS/UPLS-DA algorithm to discriminate between normal and cancer cell lines: a feasibility studyÉ uma honra apresentar este número temático virtual dos periódicos Analyst e Analytical Methods dedicado à Ciências Analíticas no Brasil. Esta iniciativa oportuna da Royal Society of Chemistry acontece em um período particularmente especial e importante para os pesquisadores brasileiros, visto que recentemente as agências de financiamento nacionais e estaduais têm feito esforços excepcionais objetivando uma melhora consistente na qualidade das pesquisas, desenvolvimentos e inovações desenvolvidas no Brasil, que são expressos de forma significativa nos programas “Institutos Nacionais de Ciência e Tecnologia” e “Ciência sem Fronteiras”. O programa “Institutos Nacionais de Ciência e Tecnologia” tem a finalidade de agregar grupos de pesquisa de todo o Brasil em Centros Virtuais para realizar pesquisas colaborativas nas fronteiras da ciência em áreas estratégicas nacionais, para dar suporte ao desenvolvimento sustentável do país e estimular a inovação em ciência. “Ciência sem Fronteiras” é um programa de mobilidade e intercâmbio internacional com o objetivo de expandir e consolidar ainda mais a ciência, tecnologia e inovação, encorajando e apoiando os processos de internacionalização das universidades e centros de pesquisa. Além disso, são criadas oportunidades para a implementação de projetos de colaboração de longa duração entre pesquisadores brasileiros e pesquisadores internacionais com elevada experiência, promovendo também o intercâmbio de estudantes de graduação e pós-graduação, além de pós-doutorandos, com instituições internacionais de alto nível. Enquanto estes programas certamente melhorarão a competitividade da pesquisa brasileira, é a ciência conduzida pelos pesquisadores envolvidos que darão vida a estes programas.

O tópico deste número temático é extremamente significativo, uma vez que enfatiza a importância da química analítica em um cenário científico global. Por um bom período, a química analítica foi considerada uma área periférica da química e os químicos analíticos eram vistos apenas como provedores de dispositivos e métodos para análises qualitativas e quantitativas demandadas, por exemplo, pelas indústrias (controle de qualidade e de processos), laboratórios clínicos e monitoramento ambiental. Entretanto, durante as últimas décadas a “química analítica convencional” sofreu uma notável evolução, transformando-se em “ciências analíticas modernas”, que pode ser, não totalmente, mas em parte certamente atribuída aos avanços da microeletrônica, microfabricação, nanomateriais/nanotecnologia e quimiometria. Atualmente, as ciências analíticas modernas amadureceram, tornando-se uma disciplina de pesquisa altamente interdisciplinar, ágil e transformadora, abordando, por exemplo, de tecnologia analítica de processos à análise de uma única célula, de monitoramento ambiental à química verde, de diagnósticos clínicos/médicos ao sensoriamento (bio)químico e de análise de composição de materiais à quantificação de contaminantes em alimentos. Adicionalmente, além de determinar “o que” e “quanto” existe de um constituinte-alvo, a química analítica contemporânea adicionou os domínios espaciais, temporais e de especiação à estes parâmetros, isto é, “onde”, “quando” e “como” um analito está presente dentro de uma determinada matriz. Em outras palavras, a Química Analítica evoluiu para uma disciplina chave da química moderna, movendo-se de sua periferia para o seu núcleo central.

Qual a situação das Ciências Analíticas no Brasil? Esta foi a questão que fizemos quando foi lançada a ideia de um número especial neste tema. O Brasil está ainda focando em “química analítica” ou está contribuindo ativamente com desenvolvimentos inovadores em “ciências analíticas”? Enquanto esta questão pode ser certamente respondida sob diferentes aspectos e considerações, a resposta da comunidade de química analítica brasileira fala por si mesma: dois meses após a data limite para submissão de artigos para este número especial, 38 manuscritos haviam sido aceitos para publicação, os quais documentam de forma notável a relevância, a vitalidade e a inovação das ciências analíticas no Brasil. Mais importante e para particular satisfação dos Editores, em vez de regiões específicas – e provavelmente favorecidas financeiramente – dentro do Brasil, as contribuições têm sido submetidas de norte a sul e de leste a oeste do país. Por exemplo, enquanto as regiões ao norte e à oeste eram certamente consideradas “distantes” dos epicentros da ciência, isto mudou dramaticamente durante os últimos trinta anos, assim como a química analítica. De uns poucos Programas de Pós-Graduação em universidades no sul e sudeste, o cenário científico expandiu-se para proporcionar uma ampla multiplicidade, espalhada por todo o país. Este imenso esforço de pesquisadores de diferentes estados, que foram as sementes destes novos programas, hoje reflete na diversidade e força do ensino de química por todo o Brasil. Portanto, a resposta é claramente “sim”. O Brasil dedica-se e contribui para as ciências analíticas modernas, acima e além das contribuições publicadas neste número especial!

Finalmente, os Editores deste número temático – Prof. Ivo M. Raimundo Jr. (Universidade Estadual de Campinas, Brasil) e Prof. Boris Mizaikoff (Universidade de Ulm, Alemanha) – gostariam de agradecer profundamente May Copsey (Editora) e Rebecca Brodie (vice-editora) por tratar de todos os detalhes referentes à esta edição, a qual não seria possível sem suas generosas assistências. Além disso, gostariam também de agradecer o Instituto Nacional de Ciências e Tecnologias Analíticas Avançadas, que forneceu as bases para esta iniciativa. Por fim, mas não menos importante, gostariam de agradecer todos os pesquisadores brasileiros que contribuíram para este número, possibilitando que o Analyst e o Analytical Methods proporcionem aos seus leitores um sabor especial das Ciências Analíticas atualmente produzidas no Brasil!

Chemistry and Art

Will there be blood? - by Caroline Grainger

2014 is the Royal Society of Chemistry year of Chemistry and Art! There have been a number of initiatives around this, and we are pleased to promote some recent work the Analyst and Analytical Methods has been involved in.

50 Shades of Green - by Paul Jackson

Founded by Yalda Javadi, Ionic Magazine aims to bridge the gap between science and art and is published as an online magazine four times a year. Javadi says ‘The two subject matters are often considered to be poles apart and from two very different worlds. Science is about truth, about following rules and laws that help answer fundamental rational questions, whereas art invokes emotional connections through expression, impressions, concepts and creations. Yet both create a sense of mystery, both are matched when it comes to skill, creativity, imagination and impact.’

She created Ionic Magazine as a way to visually express modern day scientific breakthroughs. The ultimate goal: a stunning and stimulating collaboration of two traditionally contrasting worlds.

Fishing for isinglass - by Angie Brown

In collaboration with the Royal Society of Chemistry, Issue 6 of Ionic Magazine has a selection of papers from the Molecular Analysis for Art, Archaeometry and Conservation themed collection. This collection of papers across Analyst and Analytical Methods highlighted cutting edge analytical research from academia, national laboratories and museums showing the most recent analytical breakthroughs in the field of cultural heritage. The articles described those techniques recently employed to study art and cultural objects at the molecular level, characterising their structure, properties and chemistry.

Why not take a look at the beautifual and fascinating collection of artwork inspired by this selection of research papers?

As Javadi asks -Right side or left side brain, which way do you swing?

A selection of these papers will be free to read until Aug 3rd.

You may also be interested to read the lates issue of Chemistry World, a special issue of Chemistry and Art.

175 Faces of Chemistry – Martha Whiteley

Martha Whiteley

Martha Whiteley

“There is a long-established and inveterate prejudice… that girls are less capable of mental cultivation, and less in need of it, than boys” reported the 1868 Schools Inquiry Commission.

Analyst, and the historic J. Chem. Soc., Trans. contributor Martha Whiteley did much to reverse this prejudice, for which she has been nominated as an “175 Face of Chemistry”.

This Friday, why not take some time out to explore our journal archives, discover her research, and read about her campaigning for women fellows’ admission to the Royal Society – and the problems along the way (why should men be preferred simply because ‘they wear a distinctive dress and are privileged to grow a moustache?’ – Nature editor, 1909).

Identifying DNA stucture using SERS

Detecting G-quadruplexes using SERS of silver nanoparticles

Differentiating quadruplexes from duplexes using silver nanoparticles and SERS

A promising drug target and ligand-binding site, G-quadruplexes form via Hoogsteen hydrogen bonding in guanine bases. These quartets are rich in guanine and are stabilized through π-π stacking interactions and a cation such as potassium or sodium. As researchers explore new compounds to target this region to treat diseases such as cancer, the structure of these quadruplexes and their response to ligands compared to standard DNA remains understudied. 

Researchers at the University of Strathclyde have used the sensitivity of surface-enhanced Raman spectroscopy (SERS) to detect the formation of G-quadruplexes in the presence of stabilizing ligands and silver nanoparticles. They successfully differentiated the quadruplex DNA structure from the duplex based on the SERS signal, and demonstrated the capability of SERS in identifying higher order DNA structures. To read more about the qualitative detection of these structures, click the link below. It will be free to read until June 30.

Graphene Hybrids Join the Hunt for Mercury

Graphene-polyfuran hybrids for Hg sensing

Graphene-polyfuran hybrids for Hg sensing

Commonly associated with dental fillings, mercury has a wide range of industrial and domestic applications. However, it can be toxic to humans and the environment even in small concentrations, and has been linked to a number of fatal diseases including pulmonary edema and cyanosis.

Previously developed methods of mercury detection include photochemical, colorimetric and oligonucleotide-based approaches. However, these methods can be slow, expensive and associated with low sensitivity and selectivity for the analyte. Graphene composite materials, with their unusual and enhanced conductivity properties, are an attractive prospect for metal ion analysis.

Researchers led by Professor Jyongsik Jang at the Seoul National University, Korea, have developed a new class of graphene oxide-polyfuran nanotube hybrids. In this “HOT” Analyst paper, the authors test the potential of their graphene-based materials as high performance sensors for mercury ion detection. This method has proved to be highly selective for Hg2+ over other metal ions and has excellent sensitivity even at low mercury concentrations.

This article will be free to read until 30th June.
