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
