Metals in health & nutrition

Vitamin pills with different metals indicated on eachMetals play an important role in human health and nutrition. Some, such as zinc, copper and iron have vital roles within the body and therefore regular intake is essential. However, an excess of these metals, or consumption of metal contaminants such as cadmium or arsenic, can have significant detrimental effects on our health.

The collection of articles below encompasses all aspects of metals in health from their dietary sources and quantitative analysis to the impact these metals can have on our health. Enjoy these articles from Analytical Methods, Food & Function and Metallomics for free*

Chemometrics in analytical science

Used particularly heavily in analytical chemistry and metabolomics, ‘chemometrics’ is the science of using mathematical or statistical methods to extract information from a chemical system. Beginning in the 1970s with the emergence of computer driven scientific investigation, chemometrics frequently uses methods found in applied mathematics, computer science and statistics.

Analytical Methods presents an excellent forum for such work, and below is a sample of the high-quality work we have published in this area.  These articles are free to access until 21st June 2012 so make the most of this opportunity and take a look!

Analytical methods for forensic science

Forensic kitBy definition, forensic science is the use of science to answer questions that are of interest to a legal system. Today the average person is far more familiar with forensics thanks to popular televisions series, books and films where the pivotal clue is usually discovered by the scientist. Forensic science has also been in the headlines a lot lately in the UK with the recent closure of the Forensic Science Service.

Specialties in forensics can include the analysis of blood, DNA, drugs, arson residues, documents, fibres, hair and explosives, just to name a few.

Analytical Methods presents an excellent forum for such work, and below is a sample of the high-quality work we have published in this area.  These articles are free to access until the 30th May 2012 so make the most of this and take a look!

Developments and applications of electrophoresis

Electrophoresis is a very useful separation method employed in a great variety of applications, including the separation and analysis of biological samples (e.g. DNA and proteins) and environmental samples (e.g. pesticide or pollutant analysis).  Electrophoresis comes in various different forms (capillary or gel electrophoresis for example) making it a very versatile and adaptable technique.

Analytical Methods presents an excellent forum for advances and applications of this technique, and below is a sample of the high-quality work we have published in this area.  These articles are free to access until the 13th February 2012 so make the most of this and take a look!
