Human protein shown to remove E coli from drinking water

Researchers in Japan have shown that they can remove Escherichia coli from drinking water using tiny tubes made of human serum albumin. Practical application of this finding is not obvious and is yet to come.

Graphical abstract: An Escherichia coli trap in human serum albumin microtubes

We describe the template synthesis of human serum albumin microtubes (MTs) and highlight their Escherichia coli (E. coli) trapping capability with extremely high efficiency. The E. coli was loaded into the one-dimensional pore space interior of the tubule. Similar MTs including an Fe3O4 layer also captured E. coli and were manipulated by exposure to a magnetic field.
