“…This suggests that the rate of incorporation of potassium ions is faster than its release. Thus, the reduction of Fe 4 III [Fe II (CN) 6 ] 3 is more facile than the oxidation of K 4 Fe 4 II [Fe II (CN) 6 ] 3 …”

“…[Fe II (CN) 6 ] 3 is more facile than the oxidation of K 4 Fe 4 II [Fe II (CN) 6 ] 3 . 69 The much more poorly defined redox couple in Figure 4c implies that Na + ions cannot as readily enter the PB lattice during the reduction process. 70 Despite the difficulty of inserting Na + ions into the PB lattice during the potential scan, a mass change is still evident in Figure 4c.…”

Mass loadings and mechanistic insights into the stepwise formation of Prussian blue (PB) in a carbon nanotube nanocomposite electrode,formed by an in situ electrochemical reaction between iron species filling the carbon nanotubes cavities and ferricyanide ions in solution, have been probed by electrochemical quartz crystal microbalance (EQCM), electrochemical surface plasmon resonance (SPR), and scanning electrochemical microscopy (SECM). Changes to the interfacial nanotube “electrode/electrolyte” (aqueous KCl) region during PB oxidation and reduction and the influence of the applied potential also have been assessed by EQCM mass and SPR refractive angle changes that reflect the local redox activity. The data obtained confirm that KCl present as the supporting electrolyte participates in PB formation, and SECM studies reveal that redox activity takes place at both metallic centers in PB. Large changes in the SPR angle with variation in applied potential and electrolyte cation in the carbon nanotube/PB film suggest that the nanocomposite material represents a promising material for the development of nanostructured optical devices.

“…The emergence of nanomedicine has given PBNPs new significance in the field of DDS. PBNPs are iron based nanoparticles and can be prepared in large quantities by simple methods at low temperatures [ 93 ]. Similar to iron oxide nanoparticles, PBNPs have proven to be a powerful contrast agent for MRI with the application of DDS, and their chemical stability, cytotoxicity and cell penetration have also been demonstrated [ 94 ].…”

In recent years, Prussian blue nanoparticles (PBNPs), also named Prussian blue nano-enzymes, have been shown to demonstrate excellent multi-enzyme simulation activity and anti-inflammatory properties, and can be used as reactive oxygen scavengers. Their good biocompatibility and biodegradability mean that they are ideal candidates for in vivo use. PBNPs are highly efficient electron transporters with oxidation and reduction activities. PBNPs also show considerable promise as nano-drug carriers and biological detection sensors owing to their huge specific surface area, good chemical characteristics, and changeable qualities, which might considerably increase the therapeutic impact. More crucially, PBNPs, as therapeutic and diagnostic agents, have made significant advances in biological nanomedicine. This review begins with a brief description of the synthesis methods of PBNPs, then focuses on the applications of PBNPs in tissue regeneration and inflammation according to the different properties of PBNPs. This article will provide a timely reference for further study of PBNPs as therapeutic agents.

This manuscript presents in-situ electrochemical synthesis of Prussian Blue-gold nanoparticles (PB-AuNPs) composite for application in hydrogen peroxide (H 2 O 2) biosensor. The SEM image clearly showed the presence of AuNPs of size in range of 50 to 200 nm spread on PB matrix. UV-Visible spectra showed absorbance peak at 530 nm corresponding to AuNPs and a hump in 690-740 nm region for PB, confirming the synthesis of composite. The cyclic voltammetry (CV) showed the surface coverage of 3.65 x 10-9 mol/cm 2 for pure PB film and 4.33 x 10-9 mol/cm 2 for PB-AuNPs film, with diffusion coefficient of 1.19 x 10-9 cm 2 /s, and 5.64 x 10-9 cm 2 /s respectively. The film thickness is found to be 2.4 x 10-12 cm for PB and 2.9 x 10-12 cm for PB-AuNPs composite. The concentration of redox active centers (Fe +3/+2) is 3.5 moles/cm 3 for ITO/PB and 4.1 moles/cm 3 for ITO/PB-AuNPs respectively. The CV of ITO/PB showed one redox couple at 0.118 V and 0.215 V, whereas with ITO/PB-AuNPs electrode, two sets of well-defined redox peaks; (i) 0.095 V & 0.135 V and (ii) 0.74 V & 0.78 V were obtained. The faradic current obtained with ITO/PB was 3.6 x 10-3 A and 7.3 x 10-3 A for ITO/PB-AuNPs composite film, respectively. The faradic current was almost double in presence of gold nanoparticles, as compared to pure PB. For H 2 O 2 biosensor, the horse radish peroxidase (HRP) was immobilized on composite film and was used for H 2 O 2 detection. The linearity was obtained from 10 to 90 nM, with sensitivity of 0.73µA/nM and the apparent K m value was 45 nM. The response time of reported biosensor is 20 sec and is stable for about three months.
