Cellular metal ion sensing using DNAzymes
"Metal ions are important elements in biology and are involved in numerous reactions essential for maintaining life on earth. Most commonly, metal ions confer their role as structural elements or catalytic cofactors within metalloproteins. Metalloproteins comprise more than half of all known …

The insulated gate field effect transistor (IGFET) as a microluminometer
… sensitivity relates to its electrical operation, and explores its usefulness as a microluminometer for a chemisensor and biosensor. Although the experiments performed for this dissertation show that the IGFET's light sensitivity does not involve the standard operation of the FET, i.e., the …

Synthesis, functionalisation and characterisation of germanium nanocrystals & their applications
… about how to control their size, shape, composition and surface chemistry, allowing fine control of their photophysical and electronic properties. However, genuine concerns have been raised regarding the heavy metal content of these materials, which is toxic even at relatively low concentrations …

Sensing in biological systems
Metal ions are critical to a range of mammalian cell functions, including cell signalling, proliferation, differentiation and death. As such, changes in metal ion homeostasis can have a significant effect on cell health. Fluorescent chemosensors, in combination with specialised imaging …

A Novel Use for Ionic Polymer Transducers for Ionic Sensing in Liquid
Ionic electroactive polymers have been developed as mechanical sensors or actuators, taking advantage of the electromechanical coupling of the materials. This research attempts to take advantage of the chemomechanical and chemoelectrical coupling by characterizing the transient response as the …

In vitro selection of DNAzymes selective for monovalent metal ions and their development as sensors in living cells and organisms
Beyond the function of carrying genetic information, the recognition function (DNA aptamers), the structural function (DNA origami and DNA nanodevices), and most interestingly, the catalytic function (deoxyribozymes or DNAzymes) of DNAs have been explored since 1990s, which attract widespread …
