Ultrafiltração de fluxo tangencial (TFU) é um método de recirculação utilizado para a separação baseada no peso de biosamples. TFU foi adaptada ao tamanho de seleção (1-20 nm de diâmetro) e altamente concentrar uma grande quantidade de nanopartículas de prata polidispersos (4 L de 15,2 ml ug<sup> -1</sup> Até 4 ml de 8,539.9 ml ug<sup> -1</sup>) Com agregação mínima.
