Abstract: The invention relates to a method for obtaining porous hollow fibres having molecularly imprinted spheres embedded therein, said method comprising the steps of: simultaneously and independently injecting a doping solution and a pore forming solution into an extrusion die; extruding or spinning porous hollow fibres; coagulating the porous hollow fibres that leave step (b) in an aqueous solution with an aqueous solution having a temperature between 15 DEG C -25 DEG C; winding the flexible porous hollow fibres coagulated in step (c); leaving them to dry and storing same under vacuum conditions. The resulting porous hollow fibres are used to form filtration modules in which a plurality of fibres are disposed longitudinally and in parallel. The filtration modules can be assembled together to form filtering devices intended, in a preferred example, for gradual blood purification and the subsequent qualitative and/or quantitative identification of the molecules retained in the first filter o f each filtering module. The invention also relates to the operating method of the filtering device.
