Nanoparticle-Based Microextraction Techniques in Bioanalysis
Bioanalysis, 2011Nanoparticles (NPs) have attracted a great deal of attention in the last decade due to their exceptional mechanical, optical and electronic properties. This article deals with the use of NPs as probes for the extraction of biomolecules from biological samples. In this context, NPs present some advantages compared with conventional sorbents.

Microextraction techniques in therapeutic drug monitoring
Biomedical Chromatography, 2012ABSTRACTTherapeutic drug monitoring (TDM), as part of clinical process of medical treatments, is commonly used to maintain ‘therapeutic’ drug concentrations. TDM is useful to identify the causes of unwanted or unexpected responses, to prevent unnecessary diagnostic testing, to improve clinical outcomes, and even to save lives. The determination of drug

Microextraction Techniques in Breath Biomarker Analysis
Bioanalysis, 2014Breath volatile organic compound analysis may open a non-invasive window onto (patho)physiological and metabolic processes in the body. Breath tests require controlled sampling with respect to different breath phases and on-site and point-of-care applicability.

Hollow fiber microextraction: a new hybrid microextraction technique for trace analysis
Analytical and Bioanalytical Chemistry, 2018A new hybrid microextraction technique (hollow fiber microextraction) is presented that uses the main concepts and advantages of the modern miniaturized devices used for trace analysis. This novel analytical approach uses devices made of polypropylene membranes (10.0 mm long and 0.6 mm internal diameter) in which convenient organic solvents are ...
