Structure Induced Ion Recognition of Self-Assembled Monolayers on Gold

Jiang Z., Liu S., Gao Z., Institute of Bioengineering and Nanotechnology, SG

The construction and characteristics of self-assembled monolayers(SAMs) anthraquinone-polyether compounds on gold were described. Surprisingly and in contrast to the behavior of the in solution, the SAMs show very high affinity towards alkali metal ions, as [...]

Electrocatalysis at a Thin Multi-Wall Carbon Nanotube Film Modified Glassy Carbon Electrode

Fei J., Sun Y., Hu S., Gao Z., Institute of Bioengineering and Nanotechnology, SG

Sensitive and selective ascorbic acid biosensors were developed for the determination of ascorbic acid (AA) based on glassy carbon electrode (GCE) coated with a thin multi-wall carbon nanotube (MWNT) film. The MWNT film showed excellent [...]

A Disposable Glucose Biosensor Based on Diffusional Mediator Dispersed in Nanoparticulate Membrane on Screen-Printed Carbon Electrode

Gao Z., Xie F., Shariff M., Arshad M., Ying J.Y., Institute of Bioengineering and Nanotechnology, SG

In this paper, we described a disposable glucose biosensor based on co-dispersion of a diffusional polymeric mediator and glucose oxidase (GOX) in nanoparticulate membrane on screen-printed carbon electrode. The biosensor exhibited classical features of a [...]
