In the past decade a large amount of analysis techniques have been scaled down to the microfluidic level. However, in many cases the necessary sample preparation, such as separation, mixing and concentration, remains to be performed off-chip. This represents a major hurdle for the introduction of miniaturized sample-in/answer-out systems, preventing the exploitation of microfluidic’s potential ...

Revered-phase LC-electrospray ionization mass spectrometry was used to selectively determine enalapril from plasma with minimal sample preparation. Detection limit of the method was 1 ng/mL. Precision (within day and between days) and accuracy of the method at various concentrations were acceptable. The analytical technique was used for pharmacokinetic studies after administration of enalapril ...

This report demonstrates a colorimetric, non-enzymatic glucose assay with a low detection limit of 0.07 μM based on negatively charged gold nanorod-enhanced redox reaction. This glucose assay could generate silver nanoparticles as the readout that can be visualized by the naked eye, and only 4 femtomoles of nanorods are needed for glucose determination in one human plasma sample.

Boyacigiller et al (2006 p81) have stated that ‘A key difference between domestic and global managers is the need for global managers to deal with significantly greater complexity and to be open to the outside world.’ However, Baruch (2002 p36) has made the point that ‘although the concept of globalization reflects true business reality, the idea that there is a certain template-a “gingerbread ...

Jordan Stubleski (2018): Assessing the longitudinal trend of POP concentrations in humans using high-throughput sample preparation methods developed for low-volume samples. Örebro Studies in Chemistry 21. Human exposure to anthropogenic persistent organic pollutants (POPs) and their related effects on human health widely vary from person to person, making population-based risk assessment diffic...
