Protein‐inorganic hybrid nanoflowers are new multifunctional materials shown enhanced catalytic performance. Specially, they are used as catalyst and dye decolorizer via Fenton reaction. In this study, the Myoglobin‐Zn (II) assisted hybrid nanoflowers (MbNFs@Zn) were fabricated by using myoglobin and zinc (II) ions in different synthesis conditions. The optimum morphology was characterized SEM, TEM, EDX, XRD, and FT‐IR. The hemisphere and uniform morphology was obtained at pH 6 and 0.1 mg mL−1. The size of MbNFs@Zn are 5–6 μm. The encapsulation yield was ∼95 %. In the presence of H2O2, the peroxidase mimic activity of MbNFs@Zn was spectrophotometrically investigated in the different pH values (4–9). The highest peroxidase mimic activity was found as 3.378 EU/mg at pH 4. MbNFs@Zn was exhibited 0.28 EU/mg after eight cycles. MbNFs@Zn has lost about 92 % of its activity. The usability of MbNFs@Zn for decolorization of azo dyes such as Congo red (CR), and Evans blue (EB) was researched at different times, temperatures and concentrations. The decolorization efficiency was found maximum as 92.3 % and 88.4 % for EB and CR dyes, respectively. MbNFs@Zn has perfect properties such as enhanced catalytic performance, high decolorization efficiency, stability and reusability, and can be excellent potential materials for many industrial applications.

“…In this article, we investigate the performance of 11 proteins from common food materials including pulses (pea and mung bean), oil seeds (soy bean and peanut), cereals (oat, rice, and brown rice), root (potato), algae (chlorella), and milk (whey protein and casein) in forming HNFs and the role of enzymatic hydrolysis in improving such capabilities. Optical microscopy and scanning electron microscopy (SEM) were used to characterize the morphologies of HNFs; , energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FTIR), and X-ray diffraction (XRD) were used to determine the hybridization of the protein and metal phosphate to confirm the formation of HNFs. , We demonstrate that these proteins indeed have poor ability to form HNFs. However, decomposition of these food proteins by enzymatic hydrolysis can markedly promote the formation of highly hierarchical HNFs with different morphologies.…”

Protein−inorganic hybrid nanoflowers (HNFs) possess unique properties in promoting surface reactions and have attracted wide-spread attention as a newly developed nanomaterial. However, the availability of protein sources has been mostly limited to enzymes, which narrows the application of HNFs. This study first investigated the HNF formation ability of soy protein, which shows poor performance in its native state. We show that treatment of the protein by enzymatical hydrolysis can significantly promote its ability to form HNFs, by enhancing its flexibility and mobility and increasing the nucleation sites of HNFs. The hydrolyzed soy protein also showed broad ability to form HNFs with many types of metal ions including Cu 2+ , Mn 2+ , Fe 2+ , and Ca 2+ indicated by both optical microscopy and scanning electron microscopy (SEM). Furthermore, the hydrolyzed soy protein-based HNFs display high encapsulation capacity of natural water-soluble Monascus red pigment (550 mg/(g HNF)) and oil-soluble curcumin pigment (21.9 mg/(g HNF)), while effectively improving the thermal stability and ultraviolet (UV) light stability of these pigments. Finally, 10 more food proteins were subjected to enzymatic hydrolysis, and all of them demonstrate pronounced improvement in their HNF formation ability. This research demonstrates that enzymatic hydrolysis is an effective tool for utilizing abundant food proteins to fabricate HNFs, and these food protein-based HNFs have high potential as novel delivery systems�especially for sensitive natural pigments�for food, cosmetic, and medicinal applications.

In this study, the extract of one of the red algae, Gigartina skottsbergii was used for synthesis of organic@inorganic hybrid nanoflower (hNFs) for the first time. hNFs were sytematically synthesized with different concentrations of algal extract (from 0.5 to 1.65 ml) and Cu2+ in different pHs (7.4 and 9) of PBS. Hierarchical synthesis of hNFs in the PBS buffer did not occur in the acidic medium (pH: 5). The morphological structures of hNFs were detailed with FE-SEM images. hNFs synthesized in morphology closest to the ideal flower structure with variable algal extract concentrations and pH were determined by FE-SEM. Organic and inorganic groups (structural components of hNFs), crystallinity of optimum synthesized hNFs were detailed by FT-IR, EDX and XRD analysis, respectively. It has been recorded that synthesized hNFs have antioxidant properties. hNFs have captured catalytic dyes with peroxidase-like activity. The ability of hNFs in destroying the dye in the presence of H2O2 has been attributed to the Fenton reaction. As a result, an easily applicable, inexpensive, one-step catalyst was synthesized using the Fenton mechanism. It is foreseen that the study data can be applied for nanotechnology field and basic sciences.
