Recent Advances of Prussian Blue-Based Wearable Biosensors for Healthcare

Tissue-like Conductive Ti3C2/Sodium Alginate Hybrid Hydrogel for Electrochemical Sensing

“…To experimentally testify the anti-interference capacity of the PB@Ti 3 C 2 /SA sensor, several common interferences existing in tissue fluids, including H + , OH – , glucose, urea, uric acid (UA), ascorbic acid (AA), and dopamine (DA), were added during the amperometric detection of hydrogen peroxide (Figure c). Regarded as an “artificial enzyme”, the strong selectivity of PB particles not only enabled the sensor with an accurate detection ability toward hydrogen peroxide but also endowed the sensor with a strong ability to resist interference. , Although the addition of interferences introduced fluctuations in the signal, the current response generated by these interferences is normally less than 10% of the target response, indicating the potential of the PB@Ti 3 C 2 /SA sensor in practical sensing (Figure d). Moreover, the sensing repeatability of the PB@Ti 3 C 2 /SA sensor was also investigated.…”

Beyond Nonactin: Potentiometric Ammonium Ion Sensing Based on Ion-selective Membrane-free Prussian Blue Analogue Transducers

“…PBAs could store ions in crystal sites and meanwhile have excellent electron transfer reversibility. 39,40 Moreover, the facile synthesis, low toxicity, and low-cost make PBAs suitable for largescale applications.…”

“…Prussian blue analogues (PBAs) are a sort of representative redox and ion intercalation materials that have been focused in battery fields − because they are characteristic of both electronic and ionic conductor (Figure c). PBAs could store ions in crystal sites and meanwhile have excellent electron transfer reversibility. , Moreover, the facile synthesis, low toxicity, and low-cost make PBAs suitable for large-scale applications.…”

Disruptive Strategy To Fabricate Three-Dimensional Ultrawide Interlayer Porous Carbon Framework-Supported Prussian Blue Nanocubes: A Carrier for NiFe-Layered Double-Hydroxide toward Oxygen Evolution

“…With the burgeoning focus on the potential applications of metal–organic frameworks (MOFs) in multifarious fields recently, Prussian blue (PB) and Prussian blue analogues (PBAs), an extremely easily available subcategory among 20,000 MOFs, re-enter into people’s horizons. − Despite the span of PB over three centuries, just over the past one and a half years from 2021 to October 2022, there have been 29 published reviews recorded in Web of Science on the synthesis techniques and applications of PB/PBAs mainly related to energy storage and conversion, − catalysis, − and electrochemical sensors. , In particular, because of their advantageous features including the low-cost, environmental benignity, open framework, compositional control, excellent redox activity, high cycling stability, and highly reversible phase transitions of PB/PBAs-based electrodes, PB/PBAs have been extensively explored as promising active materials in electrochemical applications such as energy storage devices, electrocatalysis, and sensors in the last decade. ,,,− Nevertheless, the poor conductivity of PB/PBAs with cyanide bridges frequently frustrates their practicability in the electrochemistry-related applications, and compositing highly conductive materials such as carbon materials is the simplest way for facilitating electron transfer and enhancing electrochemical kinetics. , …”
