Figure 5From: Preparation of α-mannoside hydrogel and electrical detection of saccharide-protein interactions using the smart gel-modified gate field effect transistorDetection of Con A using α-man gel-modified FET. (a) Time course changes of threshold voltage [VT] of 4DS20-modified FET for additions of buffer with and without 5 μM Con A investigated at 25°C (pH = 6.9, I = 0.3 M). (b) VT shifts as a function of Con A concentration on the 4DS50-modified FET investigated at 25°C (pH = 6.9, I = 0.3 M) (n = 3).Back to article page
