“…Para obtenção das esferas de QT e GCCM foi utilizado o método de coagulação [24,28,29] . A solução de QT 3% (m/v) foi preparada em ácido acético 1% (v/v), sob agitação, durante 24 h. Essa foi gotejada em uma solução de GCCM 1% (m/v) em NaOH 1 mol/L através de um sistema com seringa hipodérmica comercial acoplado a uma bomba dosadora peristáltica (Milan -modelo 202) para a formação das esferas.…”
