Maja Vuckovac da abokan aiki a Jami'ar Aalto ta Finland ne suka yi wannan binciken mai ban mamaki da sauri fiye da ruwa a cikin capillaries na musamman.
Filin microfluidics ya haɗa da sarrafa kwararar ruwa ta cikin yankuna masu ƙarfi na capillaries-yawanci don kera na'urori don aikace-aikacen likita. Ruwan ɗanɗano kaɗan shine mafi kyau ga microfluidics saboda suna gudana cikin sauri da sauri.
A madadin haka, ana iya haɓaka kwararar ruwa ta amfani da murfin superhydrophobic wanda ya ƙunshi micro- da nanostructures waɗanda ke rikitar da matattarar iska.Wadannan matattarar sun rage girman yanki tsakanin ruwa da farfajiya, wanda hakan ya rage juzu'i - ƙara kwarara ta 65% Duk da haka, bisa ga ka'idar yanzu, waɗannan matakan kwarara suna ci gaba da raguwa tare da haɓaka danko.
