Rechargeable Zn-air batteries (ZAB) have drawn extensive attention due to their eco-friendliness and safety. However, the lack of high-performance low-cost oxygen redox reactions (OER ORR) catalysts has become one main stumbling blocks in development. Herein, we successfully fabricate a CoFe nanobubble encapsulated nitrogen-doped carbon nanocage on wood support ([email protected]/WC) via pyroly...
F erritin is a protein whose principal role within cells is the storage of iron in a nontoxic, but bioavailable, form. The assembled ferritin molecule, often referred to as a nanocage, can store up to 4,500 atoms of iron (for review see ref. 1). In contrast to cytosolic ferritin, serum ferritin is relatively iron-poor and may contain only a few atoms of iron. Ferritin does not have an obvious l...
Protein nanostructures have been gaining in interest, along with developments in new methods for construction of novel nanostructures. We have previously shown that c-type cytochromes and myoglobin form oligomers by domain swapping. Herein, we show that a four-helix bundle protein cyt cb562, with the cyt b562 heme attached to the protein moiety by two Cys residues insertion, forms a domain-swap...
We demonstrate temperature-controlled encapsulation and release of the enzyme horseradish peroxidase using a preassembled and covalently closed three-dimensional DNA cage structure as a controllable encapsulation device. The utilized cage structure was covalently closed and composed of 12 double-stranded B-DNA helices that constituted the edges of the structure. The double stranded helices were...
Ferritin is a nanocage protein made of 24 subunits. Its major role is to manage intracellular concentrations of free Fe(ii) and Fe(iii) ions, which is pivotal for iron homeostasis across all domains of life. This function of the protein is regulated by a conserved di-iron catalytic center and has been the subject of extensive studies over the past 50 years. Yet, it has not been fully understood...
This work investigated the preparation of chitosan nanoparticles used as carriers for doxorubicin for targeted cancer delivery. Prepared nanocarriers were stabilized and functionalized via zinc ions incorporated into the chitosan nanoparticle backbone. We took the advantage of high expression of sarcosine in the prostate cancer cells. The prostate cancer targeting was mediated by the AntiSar an...
Objective(s): Nanocarriers are drug delivery vehicles, which have attracted the attention of researchers in recent years, particularly in cancer treatment. The encapsulation of anticancer drugs using protein nanocages is considered to be an optimal approach to reducing drug side-effects and increasing the bioavailability of anticancer drugs. Epirubicin (EPR) is an active chemotherapeutic medica...
