Amplification and Filtering of Chemical Signals

Amplification and Filtering of Chemical Signals 777 Table 14-9. Substrate recycling in biosensors. 

Fig. 141. Coupling of molecular recognition and internal signal processing, e.g. amplification and chemical filtering, by coupled enzyme reactions in biosensors.

Yager and his group at the University of Washington have developed 2D paper networks for implementing Y or T sensor and H filter (Fig. 5.19) [107] chemical signal amplification [108], controlled reagent transport by modification of the channel strac-ture, width and position of source [109], malaria antigen detection [110], etc.
