“…With the obtained results, the inhibition percentage (I%) was calculated according to equation (1), where C and E correspond to the average diameter of each fungus in the control plate and on the plate with the tested solids, respectively. 11,34 Three measurements of the fungal growth diameter were made in each plate and the standard deviation was determined…”

“…[6][7][8][9][10] Several methods have been used to produce Ag nanoparticles, which are incorporated into matrices for specific applications. 11,12 Cotton fabric modification by nanostructured coatings allows obtaining new materials, in which the properties of the bioactive particles are transferred to the fabric surface. Chitin, for instance, is a high molecular weight biopolymer whose poor water solubility represents its main drawback when applied in textile finishing (which is performed usually from aqueous media).…”

In this work, the one-pot sol-gel synthesis of novel siliceous matrixes doped with carbon from spent batteries is reported. The obtained solids with silver nitrate were characterized by their antifungal activity against Aspergillus sp., Cladosporium sp. and Chaetomium globosum, three well-known cellulolytic microorganisms responsible for the deterioration of cotton fabric. In this research it was possible to develop a methodology for the impregnation of cotton fabrics (brin type) and to evaluate the antifungal efficacy. Cotton fabric containing the highest amount of carbon showed the highest antifungal activity against C. globosum and Aspergillus sp. This may be because as the amount of carbon in the silica increases, there is an increase in the surface area that facilitates an effective distribution of the active phase to act, inhibiting the fungal growth.

RESUMEN La gran cantidad de pilas que se descartan y el impacto ambiental que la inadecuada disposición de los residuos de las mismas produce impulsó a su reciclado. Tanto las pilas alcalinas como las de cinc-carbón tienen como componentes principales cinc y carbón mezclado con otros óxidos, en su relleno interno. En este trabajo se realizó la síntesis de sílice a través del método sol-gel a partir del precursor tetraetilortosilicato y del catalizador hidróxido de amonio, incorporando carbón proveniente del reciclado de las pilas en desuso en 0,1, 1,0 y 10,0 C % (p/p), respectivamente. Este soporte fue funcionalizado con el 3-aminopropiltrietoxisilano, con una relación 1:1 y, posteriormente, fue impregnado mediante la técnica de humedad incipiente con nitrato de plata, dando como resultado 1 y 2 Ag % (p/v) adsorbido. Estos sólidos se caracterizaron mediante las técnicas de SBET, DRX, titulación potenciométrica, SEM-EDX y TEM. Se evaluó la actividad antifúngica de los sólidos obtenidos frente a los hongos Chaetomium globosum, Aspergillus sp. y Cladosporium sp., mediante el test de inhibición en placa. Los mejores resultados obtenidos mostraron un grado de inhibición cercano al 100% frente a Cladosporium sp. con ambas concentraciones de Ag. En una siguiente etapa se realizarán modificaciones en la síntesis del material silíceo para aumentar su efectividad como antifúngico.
