Nanozyme haben spezifische Vorteile gegenüber natürlichen Enzymen, wie ihre einfache Produktion in großen Mengen, lange Lagerzeiten, niedrige Kosten und hohe Stabilität unter harschen Umgebungen. Kohlenstoffnanomaterialien (CNMs), einschließlich Fullerenen, Kohlenstoffnanoröhren, Graphen, Kohlenstoffquantenpunkten und Graphenquantenpunkten, sind zu einer herausragenden Substanzfamilie in den Materialwissenschaften geworden. Über die katalytischen Aktivitäten von CNMs und ihren Hybridverbindungen als eine neue Klasse von Nanozymen wurde ausführlich berichtet. In diesem Kurzaufsatz werden die jüngsten Fortschritte bei CNM‐basierten künstlichen Enzymen zusammengefasst, mit einem Schwerpunkt auf ihrer Peroxidase‐artigen Aktivität. Die enzymatischen Eigenschaften, Katalysemechanismen und neuartige Anwendungen von CNM‐Nanozymen in der Sensorik, der Therapie und der Umwelttechnologie werden diskutiert. Darüber hinaus thematisieren wir die verbleibenden Herausforderungen und ungelöste Probleme. Einhergehend mit dem raschen Voranschreiten der Bionanotechnologie haben die einzigartigen enzymatischen Eigenschaften der CNM‐Nanozyme viel Aufmerksamkeit erfahren, und sie werden auch in Zukunft ein aktives Forschungsfeld darstellen.

“…For example, CDs have been used in drug delivery [6,7], bioimaging [8,9], optical imaging, and sensing [10,11]. Of note, an increasing trend has been observed in research on the self-activities of CDs such as haemostatic [12][13][14], hypoglycaemic [15], peroxidase-like [16], and bacteriostatic [17] activities. However, in-depth investigations of CDs may be necessary, especially those used in medical-and technologyrelated fields.…”

Mulberry silkworm cocoon (MSC) carbonisata has been used for the treatment of inflammatory diseases for hundreds of years; however, after years of research efforts, little information is available on its antiinflammatory components and underlying mechanism. We developed novel carbon dots (CDs) derived from MSC carbonisata (MSC-CDs), for the first time, with an average diameter of 2.26-9.35 nm and a quantum yield (QY) of 6.32%. The MSC-CDs were prepared using a modified pyrolysis method, and no further modification and external surface passivation agent was required. With abundant surface groups, MSC-CDs showed distinct solubility and bioactivity. In this study, we innovatively used three classical experimental models of inflammation to evaluate the anti-inflammatory bioactivity of MSC-CDs. The results indicated that MSC-CDs exhibited marked anti-inflammatory bioactivity which was likely mediated by inhibition of the expression of interleukin-6 and tumour necrosis factor-a. These results suggest that MSC-CDs possess a remarkable anti-inflammatory property, which provides evidence to support further investigation of the considerable potential and effective material basis of this traditional Chinese medicine.

“…Therefore, many scientists have focused on the development of a new method for simple, fast, cheap, selective, sensitive accurate and reliable detection of H 2 O 2 [11‐45]. For this, various useful methods such as spectrophotometric , fluorimetric , chemiluminometric and electroanalytical methods have been proposed for H 2 O 2 determination. Among those, electroanalytical methods have found great attention due to its high sensitivity, ease of operation, and low cost .…”

A Pt nanoparticle modified Pencil Graphite Electrode (PGE) was proposed for the electrocatalytic oxidation and non‐enzymatic determination of H2O2 in Flow Injection Analysis (FIA) system. Platinum nanoparticles (PtNPs) electrochemically deposited on pretreated PGE (p.PGE) surface by recording cyclic voltammograms of 1.0 mM of H2PtCl6 solution in 0.10 M KCl at scan rate of 50 mV s−1 for 30 cycles. Cyclic voltammograms show that the oxidation peak potential of H2O2 shifts from about +700 mV at bare PGE to +50 mV at PtNPs/p.PGE vs. Ag/AgCl /KCl (sat.). It can be concluded that PtNPs/p.PGE exhibits a good electrocatalytic activity towards oxidation of H2O2. Then, FI amperometric analysis of H2O2 was performed under optimized conditions using a new homemade electrochemical flow cell which was constructed for PGE. Linear range was found as 2.5 μM to 750.0 μM H2O2 with a detection limit of 0.73 μM (based on Sb/m of 3). As a result, this study shows the first study on the FI amperometric determination of H2O2 at PtNPs/p.PGE which exhibits a simple, low cost, commercially available, disposable sensor for H2O2 detection. The proposed electrode was successfully applied to determination of H2O2 in real sample.
