The nanostructures were prepared in crystallite size, ranging 8–16 nm, in one pot addition setup and further washing steps, using only iron precursors and above-mentioned antibiotics as stabilizers. Nanostructures were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis methods, Fourier transform infrared (FTIR) and ultraviolet (UV) spectroscopy methods. It was found that they have well-shaped spherical form and are homogeneous in size. The quantitative analysis of nanostructured antibiotics was performed by atom absorbance spectroscopy (AAS) as well as on the basis of Lambert–Beer law. Prepared nanostructures were tested on Staphylococcus aureus and Pseudomonas aeruginosa. Obtained results demonstrated that these nanostructures are able to improve antimicrobial properties and decrease the minimal inhibitory concentration (MIC) of pristine kanamycin and ciprofloxacin antibiotics.","PeriodicalId":73845,"journal":{"name":"Journal of nanotechnology in engineering and medicine","volume":"6 1","pages":"041006"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1115/1.4033126","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63496054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a major limitation in translation of ESCs technology to pharmaceutical and clinical applications is how to induce their differentiation into tailored lineage commitment with satisfactory efficiency. Many studies indicate that this lineage commitment is precisely controlled by the ESC microenvironment in vivo. Engineering and biomaterial-based approaches to recreate a biomimetic cellular microenvironment provide valuable strategies for directing ESCs differentiation to specific lineages in vitro. In this review, we summarize and examine the recent advances in application of engineering and biomaterial-based approaches to control ESC differentiation. We focus on physical strategies (e.g., geometrical constraint, mechanical stimulation, extracellular matrix (ECM) stiffness, and topography) and biochemical approaches (e.g., genetic engineering, soluble bioactive factors, coculture, and synthetic small molecules), and highlight the three-dimensional (3D) hydrogel-based microenvironment for directed ESC differentiation. Finally, future perspectives in ESCs engineering are provided for the subsequent advancement of this promising research direction.","PeriodicalId":73845,"journal":{"name":"Journal of nanotechnology in engineering and medicine","volume":"6 1","pages":"040801"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1115/1.4033193","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63496335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
