title: Visual detection of glucose using conformational switch of i-Motif DNA and non-crosslinking gold nanoparticles.
abstract: i-Motif tuned: glucose is a ubiquitous fuel for metabolic pathways; its oxidation can trigger i-motif DNA formation. Using this unique conformational switch and non-crosslinking gold nanoparticles, a label-free colorimetric glucose sensor has been developed.
