Dialysis is a therapy that reproduces the activity of the kidneys by purifying the blood of all waste substances. It has been estimated that there are currently 50,000 Italian dialysis patients, representing 2% of health service spending. The therapy must be practiced regularly and requires adequate preparation, but it can also lead to side effects such as the loss of useful substances from the blood, such as albumin, at the same time as toxins. The aim of this study is therefore to identify a material with a high adsorption capacity and with a structure such that it is possible to obtain the winning compromise between the removal of waste substances and the loss of albumin. For this reason, three materials were chosen: polyacrylonitrile (PAN), polysulfone (PSU) and polyacrylamide with acrylic acid (PAAM-co-AA). With these materials, as many structures were then prepared: electrospun membranes, aerogels and yarn.
La dialisi è una terapia che riproduce l' attività dei reni depurando il sangue da tutte le sostanze di scarto. È stato stimato che attualmente sono 50000 i pazienti dialitici italiani, che rappresentano il 2% della spesa del servizio sanitario. La terapia va praticata con regolarità e richiede una preparazione adeguata, ma può anche comportare effetti collaterali quali la perdita di sostanze utili dal sangue, come l' albumina, contemporaneamente alle tossine. Lo scopo che tale studio si prepone è dunque quello di individuare un materiale ad elevata capacità di adsorbimento e con una struttura tale per cui sia possibile ottenere il compromesso vincente tra la rimozione di sostanze di scarto e la perdita di albumina. Per questo motivo sono, dunque, stati scelti tre materiali: poliacrilonitrile (PAN), polisulfone (PSU) e poliacrilammide con acido acrilico (PAAM-co-AA). Con tali materiali sono poi state preparate altrettante strutture: membrana elettrofilate, aerogeli e yarn.

Abstract
Dialysis is a therapy that reproduces the activity of the kidneys by purifying the blood of all waste substances. It has been estimated that there are currently 50,000 Italian dialysis patients, representing 2% of health service spending. The therapy must be practiced regularly and requires adequate preparation, but it can also lead to side effects such as the loss of useful substances from the blood, such as albumin, at the same time as toxins. The aim of this study is therefore to identify a material with a high adsorption capacity and with a structure such that it is possible to obtain the winning compromise between the removal of waste substances and the loss of albumin. For this reason, three materials were chosen: polyacrylonitrile (PAN), polysulfone (PSU) and polyacrylamide with acrylic acid (PAAM-co-AA). With these materials, as many structures were then prepared: electrospun membranes, aerogels and yarn.File | Dimensione | Formato | |
