Materials and methods for the immobilization of bioactive species onto polymeric substrates
TL;DR: In this paper, the authors proposed a method to support members having surfaces that are rendered hydrophilic for use as a substrate for the immobilization of bioactive species thereon, where polymeric surfactants are attached onto the surfaces of a support member and covalently cross-linked thereon to form a first layer.

Immobilization of enzyme biocatalyst on natural halloysite nanotubes
TL;DR: The immobilized enzymes exhibited thermal stability, good storage stability and reusability, which indicate that halloysite is a promising support material for enzyme immobilization.

Modification of polysulfone membranes 1. CO2 plasma treatment
TL;DR: In this paper, polysulfone membranes were modified with plasma of CO2 to obtain highly hydrophilic surfaces of acidic character, and it was shown that prolonged treatment caused severe surface degradation, increase of pore size and widening of their distribution.

Ureases. II. Properties and their customizing by enzyme immobilizations: A review
TL;DR: This article offers a review of reports on immobilizations of ureases covering the last two decades and surveys the immobilization techniques and support materials applied, in addition to the resulting properties of the enzymes, to provide useful guidance through the wealth of available immobilization data.

Replacement of renal function by dialysis
Gerhard Lonnemann,Karl M. Koch +1 more
TL;DR: Recent investigations suggesting that bacterial contamination of dialysate may cause repeated stimulation of immuno-competent cells including monocytes, lymphocytes and neutrophils, resulting in increased production of inflammatory mediators in end-stage renal disease (ESRD) patients are discussed.
