In situ green synthesis of antibacterial copper nanocomposite cotton fabrics using Achyranthes aspera leaf extract

Nanomaterials are finding the diversity of application at the leading edge in emerging field of nanotechnology. Coppernanoparticles (CuNPs) were in situ generated on the surface of cotton fabrics, using Achyranthes aspera leaf extract byenvironmentally benign green synthesis. The structural and morphological properties of synthesized nanocompositecotton fabrics (NCFs) were characterized by different spectral studies such as Fourier-transformation infrared (FTIR),scanning electron microscopy (SEM) coupled with energy-dispersive X-ray primary and derivative thermogravimetric(TG-DTG), differential scanning calorimetry (DSC), and X-ray diffractometer (XRD). The molecular functionalitiesof hydroxyl groups in polyphenols of A. aspera leaf extract were identified from FTIR absorption spectrum, and theyare responsible for the bioreduction of Cu+2 into Cu0 for the formation of CuNPs. The average size of the formedCuNPs from SEM studies was found to be 95 nm. The formed CuNPs were exhibited Face centered cubic (FCC)crystalline structure, and it was confirmed by XRD studies. TG-DTG analysis publicized the thermal stability ofNCFs. The tensile strength of NCFs was higher than normal cotton fabrics. These NCFs exhibited good antibacterialproperties which considered for making aprons and wound dressing materials in medicine and for packing materials

Production of anticandidal cotton textiles treated with oak gall extract / Producción de tejidos de algodón con actividad anticandidiásica tratados con extracto de agallas de roble

Candida albicans, one of the most dreadful fungal pathogens threatening humans, could not be easily prevented. The anticandidal activity of oak gall extract, Quercus infectoria (QIE), was investigated as a potential natural alternative to synthetic and chemical fungicides. QIE anticandidal potentiality was confirmed using both qualitative and quantitative assays. Cotton textiles were treated with QIE and then evaluated as anticandidal fabrics. QIE-treated textiles had a potent anticandidal activity, which could completely inhibit the inoculated C. albicans cells. The durability of anticandidal activity in QIE-treated textiles almost completely disappeared after the fourth laundering cycle. QIE could be recommended, however, as a potent anticandidal agent for preparing antiseptic solutions and emulsions and as a finishing agent for manufacturing anticandidal disposable diapers and hygienic clothes.

Candida albicans es uno de los patógenos fúngicos más terribles que amenazan la salud humana, y su prevención no resulta sencilla. En este trabajo se investigó la actividad anticandidiásica del extracto de agallas de roble (Quercus infectoria extract; QIE) como una posible alternativa natural a los fungicidas sintéticos y químicos. El potencial anticandidiásico del QIE se confirmó mediante análisis cualitativos y cuantitativos. Se trató tejido de algodón de uso textil con QIE y se lo evaluó como tela anticandidiásica. Se verificó que dichos tejidos exhibían una potente actividad anticandidiásica y que podían inhibir completamente a células de C. albicans inoculadas. La actividad anticandidiásica, sin embargo, desapareció por completo después del cuarto ciclo de lavado. Se concluye que se podría recomendar QIE como un agente anticandidiásico potente para la preparación de soluciones antisépticas y emulsiones, y como un agente de acabado para fabricar pañales desechables y ropa de higiene con propiedades anticandidiásicas.
