aqueous two

The interaction of bacterial cells with surrounding environment depends on its surface characteristics such as hydrophobicity, hydrophilicity balance and net charge. In this paper, aqueous two-phase system partitioning of Escherichia coli strains based on their difference in surface properties is introduced in a microfluidic system. While aqueous two-phase system is widely use to separate biomo...

Preparation of cationic polyacrylamide by aqueous two-phase polymerization

2010

J. Xu W. P. Zhao C. X. Wang Y. M. Wu

Cationic polyacrylamide (CPAM) was synthesized by aqueous two-phase polymerization technique using acrylamide (AM) and dimethylaminoethyl methacrylate methyl chloride (DMC) as raw materials, aqueous polyethylene glycol 20000 (PEG 20000) solution as dispersant, 2,2′-azobis(2-amidinopropane) dihydrochloride (V-50) as initiator and poly(dimethylaminoethyl methacrylate methyl chloride) (PDMC) as st...
