1. Whole Cell Biosensor
A screen-printing algal biosensor was fabricated for evaluation of toxicity of chemicals. An algal ink was prepared by mixing unicellular microalga Chlorella vulgaris cells, carbon nanotubes and sodium alginate solution. The algal ink was immobilized directly on a screen-printed carbon electrode surface using screen printing technique. The responses to the toxic compounds were faster than those of conventional electrochemical algal sensors. The present algal biosensor may serve as compact and disposable sensors.

2. Microelectrochemical Cell
A totally screen-printed micro-electrochemical cell was developed by using a glass ink. The electrochemical cell can be applied for many electroanalytical devices.

Applications:
Envitonmental Toxic Analysis Systems
Advantages:
Low Cost, High Reproducibility, Fast Response
