Membranes Containing Sorbents for Blood Detoxification

On-Chip Fabrication of Carbon Nanoparticle–Chitosan Composite Membrane

“…The second method is to embed adsorbents into the membranes during the microfabrication process. In the late 1970s, sorbent membranes were developed for heavy blood purification systems [35,36] ; however, due to manufacturing difficulties and a lack of high purity adsorbents, these membranes were not widely used [37,38] . Recently, sorbent membranes have attracted attention again with the development of science and technology [39][40][41][42] .…”

A novel approach for blood purification: Mixed-matrix membranes combining diffusion and adsorption in one step

“…In fact, in the late 1970s so-called sorbent membranes were developed. These membranes were even on the market for a certain period, produced by Enka [9][10][11][12][13][14][15]. However, due to their quick saturation, manufacturing difficulties, reduced patient convenience and lack of adsorbents with high purity [16][17][18][19], they were quickly abandoned.…”
