The fast-growing consumer demand drives industrial process intensification, which
subsequently creates a significant amount of waste. These products are discharged into the …

Peroxidases, one of the key antioxidant enzymes, are widely distributed in nature and
catalyze oxidation of various electron donor substrates concomitant with the decomposition …

Studies on plant peroxidases are reviewed in this paper, including enzyme types and
localization, molecular structure, purification and identification and gene expression and …

Electron microscopy (EM) is the standard method for imaging cellular structures with
nanometer resolution, but existing genetic tags are inactive in most cellular compartments or …

Metalloporphyrins are widely used throughout the biosphere, and of these heme (iron
protoporphyrin IX, Figure 1) is one of the most abundant and widely used. Heme shuttles …

Nanoparticles containing magnetic materials, such as magnetite (Fe 3 O 4), are particularly
useful for imaging and separation techniques. As these nanoparticles are generally …

In recent years, colorimetric biosensing has attracted much attention because of its low cost,
simplicity, and practicality. Since color changes can be read out by the naked eye …

Horseradish peroxidase is an important heme-containing enzyme that has been studied for
more than a century. In recent years new information has become available on the three …

Over the past ten years, considerable progress has been achieved in the field of
nanomaterials-based enzymes (nanozymes). In comparison with natural enzymes …

A molecular description of oxygen and peroxide activation in biological systems is difficult,
because electrons liberated during X-ray data collection reduce the active centres of redox …
