“…The fabrication process allows enough flexibility to control the microfilter characteristics like pore size and density in order to have higher flow rate, lower clogging ratio, and better recovery rate. 8,9 In recent years, different methods have been proposed to create membranes with cylindrical pores like laser interference lithography and silicon micro machining technology, 8 aperture array lithography, 10 nanoimprinting using alumina template, 11 excimer laser, 12 phase separation micromolding, 13 and more recently dissolving mold technique. 14 However, some major a) Author to whom correspondence should be addressed.…”
