Conformal coating of microparticles by utilization of traveling surface acoustic wave microfluidics

Abstract

In this study surface acoustic wave microchips were used to perform conformal coating of microparticles The reusable chips were constructed where the PDMS channel was bonded to the thin glass slide and n-dodecane was used as a coupling layer between the glass slide and the lithium niobate substrate The results showed that for the fluorescent PS particles the electric charge of the outer layer was affected by the concentration of the coating solution and the residence time of the particles in the coating solution It was also found that the residence time plays an important role in determining the electric charge For the carboxylate conjugated particles the zeta potential of the coated particles and their stability were higher than the coated fluorescent PS particles
