Abstract
Polyurethane (PU) nanofibers possess large specific surface area and excellent mechanical properties which have been used as the matrix for many applications. Phytic acid is the biocompatible and environment-friendly organic acid with excellent chelating ability of heavy metal ions due to it contains 6 phosphate groups. In this study, the PU/phytic acid nanofibrous membrane has been successfully produced by electrospinning which was used for Pb2+ removal. Though phytic acid would improve the hydrophilicity and reduce the mechanical properties to a certain extent, the phytic acid-modified PU nanofibrous membrane still possessed excellent mechanical properties. The PU/phytic acid nanofibrous membrane achieved the highest adsorption capacity (136.52 mg/g) of Pb2+ under the condition of the pH of Pb2+ solution was 6 and the adsorption temperature and time were 20°C and 10 h which was over 6 times higher the unmodified one's (21.06 mg/g). These results demonstrated that the electrospun PU/phytic acid nanofibrous membrane could obtain high adsorption capacity of Pb2+ and it would achieve the potential application in the fields of the removal of heavy metal ions.

Synthesis and characterization of antibacterial drug loaded β-tricalcium phosphate powders for bone engineering applications. JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2020; 31:16. [PMID: 31965360 DOI: 10.1007/s10856-019-6356-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 12/28/2019] [Indexed: 06/10/2023]
Abstract
Powders of β-tricalcium phosphate [β-TCP, β-Ca3(PO4)2] and composite powders of β-TCP and polyvinyl alcohol (PVA) were synthesized by using wet precipitation methods. First, the conditions for the preparation of single phase β-TCP have been delineated. In the co-precipitation procedure, calcium nitrate and diammonium hydrogen phosphate were used as calcium and phosphorous precursors, respectively. The pH of the system was varied in the range 7-11 by adding designed amounts of ammonia solution. The filtered cakes were desiccated at 80 °C and subsequently calcined at different temperatures in the range between 700-1100 °C. Later on, rifampicin form II was used to produce drug-loaded β-TCP and PVA/β-TCP powders. All the synthesized materials have been characterized from morphological (by scanning electron microscopy) and structural-chemical (by X-ray diffraction and Fourier transform infrared spectroscopy) point of view. The drug loading capacity of the selected pure β-TCP powder has been assessed. The biological performance (cytocompatibility in fibroblast cell culture and antibacterial efficacy against Escherichia coli and Staphylococcus aureus) has been tested with promising results. Application perspectives of the designed drug-bioceramic-polymer blends are advanced and discussed.

Abstract
A comprehensive review of the publications about rosin-based chemicals has been compiled. Rosin, or colophony, is a natural, abundant, cheap and non-toxic raw material which can be easily modified to obtain numerous useful products, which makes it an excellent subject of innovative research, attracting growing interest in recent years. The last extensive review in this research area was published in 2008, so the current article contains the most promising, repeatable achievements in synthesis of rosin-derived chemicals, published in scientific literature from 2008 to 2018. The first part of the review includes low/medium molecule weight compounds: Especially intermediates, resins, monomers, curing agents, surfactants, medications and biocides. The second part is about macromolecules: mainly elastomers, polymers for biomedical applications, coatings, adhesives, surfactants, sorbents, organosilicons and polysaccharides. In conclusion, a critical evaluation of the publications in terms of data completeness has been carried out with an indication of the most promising directions of rosin-based chemicals development.

Abstract
Biocompatible nanocomposite electrospun fibers containing Polyurethane/Chitosan/ $\beta $ -Tri calcium phosphate with diverse concentrations were designed and produced through the electrospinning process for bone tissue engineering applications. After the production process, density measurement, viscosity, electrical conductivity, and tensile strength measurement tests were carried out as physical analyses of blended solutions. The chemical structural characterization was scrutinized using Fourier transform infrared spectrometer (FTIR), and scanning electron microscopy (SEM) was used to observe the morphological details of developed electrospun scaffolds. Cell viability, attachment, and proliferation were performed using a L929 fibroblast cell line. Based on the physical, SEM, FTIR analysis, and cell culture studies, preferable nanofiber composition was selected for further studies. Amoxicillin (AMX) was loaded to that selected nanofiber composition for examination of the drug release. In comparison with other studies on similar AMX controlled products, higher drug loading and encapsulation efficiencies were obtained. It has been clearly found that the developed nanofiber composites have potential for bone tissue engineering applications.

Investigation of Industrial Polyurethane Foams Modified with Antimicrobial Copper Nanoparticles. MATERIALS 2016; 9:ma9070544. [PMID: 28773665 PMCID: PMC5456853 DOI: 10.3390/ma9070544] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/22/2016] [Revised: 06/17/2016] [Accepted: 06/29/2016] [Indexed: 11/22/2022]
Abstract
Antimicrobial copper nanoparticles (CuNPs) were electrosynthetized and applied to the controlled impregnation of industrial polyurethane foams used as padding in the textile production or as filters for air conditioning systems. CuNP-modified materials were investigated and characterized morphologically and spectroscopically, by means of Transmission Electron Microscopy (TEM), and X-ray Photoelectron Spectroscopy (XPS). The release of copper ions in solution was studied by Electro-Thermal Atomic Absorption Spectroscopy (ETAAS). Finally, the antimicrobial activity of freshly prepared, as well as aged samples—stored for two months—was demonstrated towards different target microorganisms.
