Thread based analytical device as an analytical platform with mobile phone has been developed as green chemical analysis for the assay of anionic surfactant. The platform involves microfluidic behavior. The thread composing a bunch of cotton fibers could serve as channel that allows anionic surfactant to move along. The part of the thread containing anionic surfactant could be seen blue when threated with methylene blue while the part without anionic surfactant showed no blue. The platform could be then photo taken. A plot of log value of concentration of anionic surfactant versus the move distance along the thread exhibits linear: y = 129x+ 371; r2 = 0.999 where x being log (SDS concentration) and y being distance.
