PlomBOX: a low cost bioassay for the sensitive detection of lead in drinking water por Dias, A, Alvarez, M, Gándola, Y, Deisting, A, Alba Posse, E, Arnaldi, H, Asorey, H, Bertou, X, Colque, A, Favela-Pérez, F, Gasulla, J, Gómez Berisso, M, Guerra-Pulido, JO, Lipovetzky, J, Lobera, J, Lovino, MB, Marpegan, L, Martín, D, Mejía Muñoz, S, Monroe, J, Nadra, AD, Pregliasco, R, Rumi, G, Rossen, A

“...The biosensor uses a genetically-modified strain of Escherichia coli, which serves as both signal amplifier and reporter of lead in water, measured via colour change. We developed the PlomBOX measurement platform to image this colour change and we demonstrate its capability to detect concentrations as low as the World Health Organisation upper limit for drinking water of 10 ppb. ...”

The crystal growth in homopolymer polyvinylidene flouride (PVDF) and copolymer polyvinylidene flouride-triflouroethylene (PVDF-TrFE) / Dzuraiezhar Ismail por Ismail, Dzuraiezhar

“...The crystalline structures were analyzed using Differential scanning calorimetry (DSC) and polarized light microscopy (PLOM). Samples were annealed to enhance crystal growth and observed using PLOM....”
