Abstract

In this paper we describe novel magnetically driven polymeric microtool for non-intrusive and no contamination experiments on a chip. The composite is formed by suspending magnetite particles in polydimethylsiloxane. In order to obtain precise and complicated pattern of micromagnetic tools, a photolithography techniques has been applied by making good use of thick KMPR-1050 photoresist as sacrifice-mold. The novelties of these tools are 1. fabrication of any 2D shape, 2.softness, 3. no contact actuation, 4. mass production with low cost. These versatile micromagnetic tools can be applied to various functions such as stirrer and valve. The potential impact of this technology includes sample selection and separation, particle loading and immobilization, genetic operation, tracking, mixing and reaction techniques into portable microfluidic labs-on-a-chip, culture systems.
