Figure 1From: Preparation of α-mannoside hydrogel and electrical detection of saccharide-protein interactions using the smart gel-modified gate field effect transistorConceptual scheme for a lectin-responsive gel-mediated signal transduction enabling a 'Debye-length-free' FET-based Con A detection. (a) Mechanism of detection of saccharide-protein interaction capitalizing on the gel-modified FET. (b) Chemical structures of the components of lectin-responsive gel.Back to article page
