Manifesting the unique properties of carbon nanotubes (CNTs), increasing attention has been paid to the use of single-walled CNTs as a promising electrode material. Therefore, CNT paste electrodes prepared by thoroughly mixing single-walled CNTs and minerals have been seen in a number of instances. Modified with a proper mediator, the resulting electrodes have shown good electrocatalytic activity toward oxidation of reduced nicotinamide adenine dinucleotide (NADH).

Toxic pollutants have always been a source of concern to the health of aquatic bodies. Ranging from the release of chemicals to oil spills, the effect of such events, particularly in terms of their impact on the population of aquatic species, have alerted us of the degree of harm they can have on the overall ecosystems. As a result, the capability to detect the presence of such pollutants has been a key concern for various government and nongovernment organizations.

Many current devices for a continuous monitoring of blood glucose levels are based on direct analysis of blood withdrawn from the tip of a finger. This is disliked by many patients since the finger sticks are painful. Therefore, the goal of more advanced glucose sensing approaches is to minimize the pain associated with monitoring blood glucose levels.

A minuscule yet ultrasensitive sensor, developed by Merlijn Hajenius for Delft University of Technology's Kavli Institute of Nanoscience, in close cooperation with the SRON Netherlands Institute for Space Research, could help further our understanding of the cosmos and outer space. Hajenius received a PhD from Delft University of Technology in January 2007 based on this research subject.
