We introduce a novel colloidal glucose sensing platform from a bottom-up approach. The essence of our approach is to detect conductance changes resulting from the adsorption of glucose onto silver nanowires on the elastomer microparticles. For this, we decorate the surface of polyurethane (PU) microparticles with silver nanowires whose surface is decorated with 4-mercaptophenylboronic acid. The conductive PU microparticles were exactly 2-dimensionally positioned in a stencil. Then, deformation of the particles under constantly applied pressure is correlated with the change of conductance, thus enabling accurate detection of glucose concentration in the given solution. These results highlight that our colloidal glucose sensor plays an important role in achieving high sensitivity over a wide range of glucose concentrations while displaying reversible sensing performance. |
