“…The recoveries of the samples were found to be in the range of 93.7-105.6% with the RSD within 5.0%. The recoveries of the samples and the RSD values were satisfactory compared with some reports [57][58][59][60][61], which proved the reliability of the proposed sensing platform for Glu determination in real samples.…”

a b s t r a c tPoly(9-fluorenecarboxylic acid) (PFCA) thin film was successfully fabricated onto the surface of indium tin oxide glass by one-step electropolymerization of commercially available 9-fluorenecarboxylic acid in boron trifluoride diethyl etherate. Meanwhile, PFCA thin film could specifically recognize Fe 3+ . Fe 3+ was generated by the oxidization of Fe 2+ in the presence of H 2 O 2 that was produced by biochemical reactions and resulted in fluorescence quenching of PFCA thin film. Furthermore, a sensing platform was designed for highly selective fluorescent detection of glucose. The qualitative and quantitative analysis of Fe 3+ , H 2 O 2 and glucose with detection limits of 1 M, 2.9 M and 3.4 M respectively could be implemented by a simple, cost-effective, reusable, practical and multi-functional PFCA thin film. The fabricated PFCA-based chemo/bio sensing film for fluorescent detection of Fe 3+ in rice sample or glucose in serum sample was assessed. Satisfactory results indicate that this work will provide not only a new strategy for fluorescent detection of important substances in agricultural science, but also significant theoretical guidance and important reference value for the practical application and development of multi-functional sensing device.

“…Cu 2 O and CuO nanomaterials are known to exhibit excellent catalytic performance in various reactions [39][40][41][42]. After oxidation of the TBA 29 -T n -Cu NPs to TBA 29 -T n -CuO/Cu 2 O NPs, we observed unique catalytic activity for H 2 O 2 -mediated AR redox reaction (Fig.…”

“…Therefore, T 30 and/or TBA 29 may have been involved in substrate binding. Hence, the catalytic The peroxidase-like activity of the TBA 29 -T 30 -CuO/Cu 2 O NPs could presumably be attributed to acceleration of their electron transfer process and, consequently, facilitation of •OH radical generation [40,44]. Electrochemical Impedance Spectroscopy (EIS) was used to investigate the electrochemical behavior of an electrode modified with the TBA 29 …”

“…However, the wide potential applications of the peroxidase-like activity of iron oxide nanoparticles in medicine and biotechnology remain to be understood yet. A recent study, performed by Gao et al, found that the Fe 3 O 4 magnetic nanoparticles (MNPs) were intrinsically active catalyst for some oxidation reactions, being similar to natural horseradish peroxidase (HRP) [57]. The peroxidase-like nature of Fe 3 O 4 MNPs was employed to replace the enzyme HRP used in H 2 O 2 detection and immune-absorbent assay and was also explored for the applications in the degradation of phenolic and aniline compounds [58].…”

Nanozymes, in nature, are artificial enzymes. Innovated by Ronald Breslow to mimic enzymes. Nanozymes have widespread applications including targeted cancer therapy, diagnostic medicine and bio-sensing even environmental toxicology. However, these applications are a novel research field in biomedicine, but are growing fast. Enzyme-based applications such as immune-absorbent assay (ELIZA) are expensive because of the complexity of producing enzymes and antibodies. Not only, some nanoparticles can mimic these enzymes such as superoxides, but also they can manipulate biological pathways directly like autophagy. These abilities make them a suitable alternative for both therapy and diagnosis. In this review, we opted on metal nanoparticles and application of this cutting edged technology into modern medicine.
