Recent Advances of Prussian Blue-Based Wearable Biosensors for Healthcare

“…Because PB/PBAs can be used for a representative biosensing process with excellent redox and electrochemical behavior, PB/PBAs as a kind of low-cost ideal electrocatalysts for wearable sensors have rapidly grown. The research strategies have mainly focused on the exploitation of PB active inks for direct or indirect analysis − and preparation of sensing layers by using 3D skeleton structure of PB/PBAs. , For example, our groups creatively reported a wearable biomolecule smartsensor based on highly electrocatalytic Berlin green nanoparticles (BGNPs) as active printing inks prepared in one step . As shown in Figure a, typical redox peaks corresponding to PB–BG circulation of BG ink-based sensor can be observed, demonstrating high electrocatalysis activity.…”
