Today’s Talk
Purpose of the Paper– Why L-Malic acid Biosensor?
Characteristics of the Sensor– Electrode Composition– Performance– Inhibitors
Results from Real Testing

Purpose of the Paper
Want a quick, simple and cheap way to detect if apples are ripe
Current Methods:– LC, GC– Capillary Isotachophoresis– FTIR Spectrometry– Enzymatic assay with Photometric Detection
L-Malic Acid amounts decrease as fruit ripens

Conclusion
Linear Range less than Test Kit:– 0.028-0.7mM vs 0.0038-2.5mM
Faster than Test Kit:– 6min vs 24min
