Metal Oxide Nanoparticles as Biomedical Materials.

The development of new nanomaterials with high biomedical performance and low toxicity is essential to obtain more efficient therapy and precise diagnostic tools and devices. Recently, scientists often face issues of balancing between positive therapeutic effects of metal oxide nanoparticles and their toxic side effects. In this review, considering metal oxide nanoparticles as important technological and biomedical materials, the authors provide a comprehensive review of researches on metal oxide nanoparticles, their nanoscale physicochemical properties, defining specific applications in the various fields of nanomedicine.

Recent advances in biomaterials for 3D scaffolds: A review.

Considering the advantages and disadvantages of biomaterials used for the production of 3D scaffolds for tissue engineering, new strategies for designing advanced functional biomimetic structures have been reviewed. We offer a comprehensive summary of recent trends in development of single- (metal, ceramics and polymers), composite-type and cell-laden scaffolds that in addition to mechanical support, promote simultaneous tissue growth, and deliver different molecules (growth factors, cytokines, bioactive ions, genes, drugs, antibiotics, etc.) or cells with therapeutic or facilitating regeneration effect.

A Novel Co₃O₄-BiPO₄ Nanoarchitectonics Material Preparation for the Electrocatalytic Detection of Epinephrine.

A novel sensing material of cobalt oxide-bismuth phosphate (Co₃O₄-BiPO₄) was prepared by the hydrothermal method. Thus prepared sensing material was characterized by X-ray diffraction analysis (XRD) and transmission electron microscopy (TEM). The sensor was used for the determination of epinephrine by using modified Co₃O₄-BiPO₄ on glassy carbon electrode (GCE).
