This chapter discusses membrane filter techniques in microbiology. Membrane filters are thin porous sheet structures composed of cellulose esters or similar polymeric materials. They act essentially as two-dimensional screens and as such, all particles, both biological and non-biological, which exceed ...

a highly efficient selectivity filter achieving both size exclusion and charge repulsion. They are abundant among all living organisms from prokaryotes to mammals and responsible for fast water transport rates of red blood cells and renal tubules. Along with their conventional roles in water transport,...
