The results show that free flow acoustophoresis can be used to perform complex separation tasks, thereby offering an alternative to expensive and time-consuming methods currently in use. Although separation of suspended micrometer-sized or smaller 2019-06-19 Acoustic separation. Free Flow Acoustophoresis (FFA) can be considered as one of the most efficient approaches for high-throughput separation of microparticles or cells from complex suspensions such as blood samples. 31,173,174 A dedicated review series has been written on the subject. 175–177 FFA uses acoustic forces generated by high-frequency acoustic resonators to separate particles or cells based … 2015-05-07 Att separera celler i mikrochip med hjälp av ultraljud är även en skonsam metod så cellerna klarar sig bra efteråt, vilket är en av anledningarna till att den är intressant. Detta arbete var en start i att försöka sortera ut vissa celler från upplöst och utspädd vävnad och har visat lovande resultat som kommer att forskas vidare på i gruppen.
