asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Isolation and separation of specific molecules is used in almost all areas of biosciences and biotechnology. Diverse procedures can be used to achieve this goal. Recently, increased attention has been paid to the development and application of magnetic separation techniques, which employ small magnetic particles. The purpose of this review paper is to summarize various methodologies, strategies...
Phase formation of manganese ferrite prepared by co-precipitation method is studied at different annealing temperatures. It is shown that the spinel phase is formed by quenching only in inert gas. XRD patterns show that the background picks fall in intensity by increasing annealing temperature and the single phase is achieved by magnetic separation.
The generation of single-stranded DNA (ssDNA) from double-stranded PCR products is an essential step in the selection of aptamers by systematic evolution of ligands by exponential enrichment (SELEX). Magnetic separation with streptavidin-coated beads is always the most commonly used method. Recently, two size separation methods derived from unequal primers with chemical or structural modificati...
