Analysis of bioparticles chaining under electrode-isolated dielectrophoresis towards flexible BioMEMS application

Formation of bioparticle chaining using flexible bioMEMS is highly potential for various applications. Using electrical actuation to form bioparticle chain is established method, however, the effect of direct contact between electrical source and bioparticle in manipulation affects the bioparticles. In this work, we demonstrated the ability to form bioparticle chains in both method, either with direct-contact and non-contact between bioparticles and electrode. We analyzed the feasibility of chaining as well as the effect of isolator thin layer upon the chain length and direction.
