“…Based on the previous reports, the blue color product should be due to the oxidation of TMB by OH·5455. Cu(II) on the surface of Cu 9 S 5 nanocrystals might produce OH· by the Fenton reaction between Cu(II) and H 2 O 2 30.…”

“…As shown in Figure 4c, when PANI was coupled with a narrow band gap semiconductor such as Cu 9 S 5 under visible light irradiation, the photogenerated electrons excited by Cu 9 S 5 will transfer from Cu 9 S 5 to PANI, which effectively prevent the recombination of the electron-hole pairs. And H 2 O 2 is a good electron scavenger to form OH· on the surface of composite nanowires, which largely enhanced the oxidation ability of TMB55. As a result, the PANI/Cu 9 S 5 composite nanowires exhibited an enhanced catalytic activity compared to the individual Cu 9 S 5 nanocrystals and PANI nanowires alone.…”

Here, we demonstrated a novel method to decorate Cu9S5 nanocrystals on polyaniline (PANI) nanowires using the dopant of mercaptoacetic acid (MAA) in the PANI matrix as the sulfur source under a hydrothermal reaction. TEM images showed that Cu9S5 nanocrystals with a size in the range of 5–20 nm were uniformly formed on the surface of PANI nanowires. Significantly, the as-prepared PANI/Cu9S5 composite nanowires have been proven to be novel peroxidase mimics toward the oxidation of the peroxidase substrate 3,3′,5,5′-tetramethylbenzidine (TMB) in the presence of H2O2. Due to the synergetic effects between polyaniline nanowires and Cu9S5 nanocrystals, the obtained PANI/Cu9S5 composite nanowires exhibit superior catalytic activity over the independent components. This work not only presents a simple and versatile method to decorate semiconductor nanocrystals on the surface of conducting polymer nanostructures, but also provides fundamental guidelines for further investigations into the synergetic effect between conducting polymers and other materials.

has a direct bandgap of 1.8 eV due to the 2D structure. [ 11 ] This unique feature brings few layer MoS 2 signifi cant improvement in optical, electronic, and mechanical properties. And the few layer MoS 2 nanosheets have been attracted great interest and applications in catalysis, [ 12 ] phototransistors, [ 13 ] solar cells, [ 14 ] lithium ion batteries, [ 15 ] electrocapacitor, [ 16 ] and fi eld emission, [ 17 ] etc. Polypyrrole (PPy) is one of the most frequently studied conducting polymers in the past few decades due to its high conductivity, high storage ability, good thermal and environmental stability, high redox and capacitive current, and excellent biocompatibility. [ 18 ] Furthermore, the synthesis and purifi cation of PPy are relatively easy. It has been reported that PPy and its derivatives could be synthesized through both chemical and electrochemical polymerization approaches in either organic or aqueous acid media. [ 19 ] Recently, PPy nanoparticles have been reported to exhibit intrinsic peroxidase-like activity, which could be employed for quantitative detection of H 2 O 2 generated by macrophages. [ 20 ] In addition, PPy and other types of conducting polymers have also be found to participate in the peroxidase-like reaction and enhance the catalytic performance. [ 21 ] In this work, we for the fi rst time prepared algae-like MoS 2 / PPy nanocomposite in a one-pot reaction. The MoS 2 /PPy nanocomposite was prepared using a hydrothermal route to have direct oxidation polymerization of pyrrole in the presence of ammonium tetrathiomolybdate, which of the obtained PPy could in situ well-distributed grown on the surface of MoS 2 sheets. We also show the peroxidase-like activity of MoS 2 /PPy nanocomposite toward the oxidation of peroxidase substrate 3,3,5,5-tetramethylbenzidine (TMB) in the presence of H 2 O 2 to produce a blue color. In addition, a comparative catalytic activity has been made with that of the independent MoS 2 and PPy nanomaterial, which revealed that the synergistic coupling effect between few layer MoS 2 nanosheets and PPy component contributed the enhanced catalytic activities.

In modern conditions, nanomaterials, especially nanoparticles of metals and nonmetals, are increasingly used in various industries. Due to their unique properties, in particular, the ability of nanoparticles to exhibit an enzyme-like effect they are widely used in biology, medicine, biotechnology, the food industry and agriculture. Important advantages of nanoparticles are their size, which enables specific properties to be present: their large surface area, the ability to transfer molecules and the ability to protect them from degradation and release over a long time, the location of action and the specificity of interaction with biological structures. Nanoparticles play a special role in the processes of neutralizing the active forms of oxygen. It has been established that a number of nanoparticles, in particular, Fe, Mn, Zn, Ce, Si and Se oxides, have an enzyme-like activity mimicking that of some enzymes. By changing the degree of oxidation, these particles can regenerate and continuously catalyze the reaction of neutralizing superoxide anion radicals, thus fulfilling the function of SOD and being the first link in protecting tissues and cells from oxidative stress in physiological and pathological conditions. It is proved that nanoparticles Mn3O4, Fe3O4, Co3O4, CeO2, LaCoO3 and other elements can effectively dispose of hydrogen peroxide and other peroxides, showing catalase-like and peroxidase-like activity. Nanozymes are characterized that exhibit the activity of oxidases, peroxidases and phosphatase. The prospect of using mimetics for complex in vitro analyzes of high-sensitivity biomarker disease detection is shown. The possibility of effective multi-use of nanoparticles as antioxidants is indicated. There are good prospects for further research on properties and the use of polyfunctional particles that are easily synthesized, reliable and inexpensive. More work is needed to determine the interaction of enzymomimetics with biological molecules such as proteins, carbohydrates and lipids, and also to take into account the peculiarities of their metabolism, clearance, degradation, biocompatibility and side effects, since individual nanoparticles have the potential to be deposited in separate organs.
