“…One of the most prominent research fields in recent years is nanotechnology. Since the 1970s, when the development of nanoscience began, this branch of science has been attracting a lot of attention from scientists and taking on ever-greater dimensions of research [ 1 ]. Nanotechnology implies a multidisciplinary type of research related to particles whose size is expressed in parts per billion (10 9 ), hence from 1 to 100 nm [ 2 ].…”

The study’s objective was to obtain silver nanoparticles (SVAgNP and FUAgNP) using aqueous extracts of Salvia verticillata and Filipendula ulmaria. The optimal conditions for nanoparticle synthesis were determined and obtained; nanoparticles were then characterized using UV-Vis, Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), Dynamic Light Scattering (DLS), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM/EDS). SVAgNP and FUAgNP possessed a crystalline structure with 48.42% and 60.41% silver weight, respectively. The highest percentage of nanoparticles in the solution had a diameter between 40 and 70 nm. In DPPH˙ and ABTS˙+ methods, FUAgNP (IC50 15.82 and 59.85 µg/mL, respectively) demonstrated a higher antioxidant capacity than SVAgNP (IC50 73.47 and 79.49 µg/mL, respectively). Obtained nanoparticles also showed pronounced antibacterial activity (MIC ˂ 39.1 µg/mL for most of the tested bacteria), as well as high biocompatibility with the human fibroblast cell line MRC-5 and significant cytotoxicity on some cancer cell lines, especially on the human colon cancer HCT-116 cells (IC50 31.50 and 66.51 µg/mL for SVAgNP and FUAgNP, respectively). The nanoparticles demonstrated high catalytic effectiveness in degrading Congo red dye with NaBH4. The results showed a rapid and low-cost methodology for the synthesis of AgNPs using S. verticillata and F. ulmaria with promising biological potential.

“…The AgNPs’ preparation methodology consists of three stages: (i) reduction reaction, which is possible thanks to the functional groups present in the compounds of the WEOP, and follows by chelation of the Ag + , subsequent reduction to Ag 0 and consequently, change of these functional groups to their oxidized form; (ii) growth of the size of AgNPs; and stabilization step, where the phytocompounds create an envelope around the AgNPs [ 40 ].…”

Green Synthesis of Silver Nanoparticles and Its Combination with Pyropia columbina (Rhodophyta) Extracts for a Cosmeceutical Application

We report the green synthesis of silver nanoparticles (AgNPs) by using daisy petals (Bellis perennis), leek (Allium porrum) and garlic skin (Allium sativum) as reducing agents and water as solvent. AgNPs are obtained with high monodispersity, spherical shapes and size ranging from 5 to 35 nm and characterized by UV-Vis and TEM techniques. The obtained yields in AgNPs are in concordance with the total phenolic content of each plant. We also study the incorporation of AgNPs in combination with the red algae Pyropia columbina extracts (PCE) into cosmetic formulations and analyze their combined effect as photoprotective agents. Moreover, we carry out the inclusion of the PCE containing mycosporine-like amino acids (MAAs), which are strong UV-absorbing and antioxidant compounds, into β-cyclodextrin (βCD) and pNIPAM nanoparticles and analyze stability and release. The thermoresponsive polymer is grown by free radical polymerization using N-isopropylacrylamide (NIPAM) as the monomer, N,N′-methylenebisacrylamide (BIS) as the cross-linker, and 2,2′-azobis(2-methylpropionamidene) (V50) as the initiator, while βCD complex is prepared by heating in water. We evaluate the nanoparticle and βCD complex formation by UV-Vis and FT-IR, and NMR spectroscopies, respectively, and the nanoparticles’ morphology, including particle size, by TEM. The cosmetic formulations are subsequently subjected to accelerated stability tests and photoprotective analyses: a synergistic effect in the combination of AgNPs and PCE in photoprotection was found. It is not related to a UV screen effect but to the antioxidant activity, having potential against photoaging.

La preocupación creciente por el control de la colonización y crecimiento de hongos y bacterias en los interiores edilicios ha impulsado distintas líneas investigativas que comprenden el desarrollo de nuevas pinturas y recubrimientos con propiedades antimicrobianas que eviten el asentamiento de los microorganismos. Estas formulaciones contienen uno o más aditivos antimicrobianos llamados biocidas. Entre los productos investigados se destacan las nanopartículas de ciertos materiales metálicos (plata, cobre, selenio y oro) que han mostrado algún grado de bioactividad. Las nanopartículas se caracterizan por contar con propiedades dependientes del tamaño y la forma, a su vez, éstas son afectadas por el método y las condiciones de síntesis. Existe un creciente interés en desarrollar procesos de obtención de nanopartículas que sean amigables con el ambiente, es decir que eviten el uso de productos químicos cuestionados desde el punto de vista de su toxicidad. Esta tendencia enmarcada en la denominada química verde tiene como objetivos principales reducir los desechos, minimizar el uso de productos no seguros y beneficiar el uso de solventes y reactivos amigables con el ambiente. La síntesis verde de nanopartículas basada en el uso de extractos vegetales acuosos resulta promisoria por ser accesible, efectiva, segura, de bajo costo, no contaminante y por ofrecer vastas posibilidades. El objetivo de esta investigación fue desarrollar nuevos aditivos antimicrobianos de base nanotecnológica obtenidos por síntesis verde, aplicables en forma eficiente en la formulación de pinturas antimicrobianas que prevengan el biodeterioro. Para lograr este objetivo se trabajó en primer lugar en la obtención, caracterización y selección de las nanopartículas con mayor actividad tanto antibacteriana como antifúngica. En una siguiente etapa, se formularon y prepararon pinturas con los aditivos antimicrobianos desarrollados reemplazando los biocidas tradicionales que se usan en las pinturas comerciales fuertemente cuestionados desde el punto de vista de la salud y el impacto ambiental.
