Dual function hollow structured mesoporous Prussian blue mesocrystals for glucose biosensors

Dual function hollow structured mesoporous Prussian blue mesocrystals (HMPB) serve both as a scaffold carrier matrix to load the enzyme glucose oxidase and as a redox mediator of H₂O₂, the by-product of glucose oxidase catalyzed glucose reaction. The red and blue symbols represent glucose oxidase and HMPB, respectively.
